Section 1: Introduction
General Description and Intended Use
The Hematek
automated, bench-top instrument designed specifically for the staining of hematology
slides for in vitro diagnostic use. This self-contained precision instrument accepts,
conveys, fixes, stains, and delivers dry blood smear preparations that are spread on
standard thickness 25-mm x 75-mm or 1” x 3” glass slides. The slides are stained at the
rate of one slide per minute.
Two conveyor spirals move the slides along the platen. Three sensing switches are
triggered sequentially as the slide moves along the platen. Each switch activates its
respective solution pump, which meters and delivers the stain, buffer, or rinse into the
capillary space between the slide and platen. After staining and rinsing have been
accomplished, the slide is dried by a flow of air from a low velocity blower and it is then
deposited in a slide drawer.
Optimal results with the Hematek Slide Stainer are obtained by using one of the Hematek
Stain Paks. The Stain Pak consists of one bottle each of stain, buffer, and rinse solutions,
and is designed for easy installation and removal from the instrument.
NOTE:
Only Hematek Stain Paks should be used with the Hematek Slide Stainer. Use of other
stain packs or solutions may void the warranty.

Theory of Operation
The Hematek Slide Stainer is designed to produce stained slides of consistent quality in a
continuous process. This is accomplished by having a fixed length of time in each of the
three phases of stain, buffer, and rinse, as well as a predetermined ratio of stain-to-buffer
volumes in the buffer phase.
A properly stained slide is the result of an interactive process involving the pump
volumes, the mixing process, and the stain-to-buffer ratio. A minimum ratio of 1:2 is
recommended; however, if the platen is filling properly, good mixing is occurring, and the
stained slides are acceptable under the microscope, the stain-to-buffer ratio should not be
adjusted.

Physical Characteristics
Figure 1-2. Circular Bubble Level and Leveling Feet, shows the physical characteristics of
the Hematek Slide Stainer, including the circular bubble level and the leveling feet.
Figure 1-2. Circular Bubble Level and Leveling Feet
1 Circular Bubble Level
2 Leveling Feet
Circular Bubble Level
CAUTION
Do not move the circular bubble level from its location directly behind the operating lever.
Proper leveling is essential for optimal mixing of the stain and buffer.
The circular bubble level is a water bubble gauge with an inscribed circle that can be
observed through the clear plastic lid of the instrument. The level is located on the
instrument panel to the left of the reagent pumps, directly behind the operating lever. It is
used to ensure the Slide Stainer is in a level position.
Levelers
The feet under the front corners of the instrument act as levelers and may be adjusted to
raise or lower the instrument to a level position. Observe the circular bubble level to verify
that the feet have been properly adjusted and the instrument is level.

Slide Transport System
Figure 1-3. Slide Transport System and Figure 1-4. Slide Transport and Staining System
show the slide transport system, including the conveyor spirals, the platen, the platen
guide rails, and the slide drawer.
Figure 1-3. Slide Transport System
1 Conveyor Spirals
2 Platen
3 Platen Guide Rails
4 Slide Drawer
Conveyor Spirals
The conveyor spirals are two parallel spirals with opposing grooves. Slides to be stained
are fitted separately into the opposing grooves, which move the slides across the staining
surface. When loading slides onto the instrument, the side covered by the blood smear is
faced to the left of the operator, with the feathered edge to the back of the instrument.
Slides are moved by the conveyor spirals side by side, from right to left, first at the vertical
plane, then at the horizontal plane with the blood smear facing downward toward the
platen.
Page 1—6, Section 1: Introduction
Page 13
Platen
The platen spans the entire front of the instrument, between the conveyor spirals. The
outside ridges of the platen are elevated guide rails, which give support to the slides as
they are moved along the platen. It is a precision-machined component made from a highperformance plastic polymer material and is designed specifically for two main functions:
1. It maintains the exact volumes of the required solutions within a capillary space between the platen and the slide.
2. It provides a mixing system for the stain and buffer.
The platen also provides the necessary time interval after the rinsing step for proper drying
of the slides before they are deposited in the slide drawer. A trough around the perimeter
of the platen allows for drainage of used solutions into the waste tank below.
Slide Drying System
The dryer is a blower type fan that runs continuously when the instrument is in operation.
The airflow serves to cool the mechanical components inside the Slide Stainer, as well as
to dry the slides.
Slide Drawer
The slide drawer is located below the left end of the platen. It receives the slides as they
drop from the platen after being stained, rinsed, and dried. The drawer will hold 100
slides. See Figure 1-4. Slide Transport and Staining System .
Waste Tank
The waste tank is located underneath the platen and collects used and overflow staining
solutions. The waste tank should be emptied and rinsed once each day and whenever a
new Stain Pak is installed. Refer to Section 5: Maintenance for more information.

3 Volume Control Panel
Volume Control Panel
The volume control panel tips out from the right front corner of the instrument and
contains three graduated adjustment knobs. The volume of reagent being delivered can be
adjusted by rotating the respective control dial clockwise to increase the volume or
counterclockwise to decrease the volume.
Solution Pumps
The instrument has three pump assemblies, one for each solution. Each assembly consists
of a pump motor, four rollers that are attached to the underside of a pump cap, and a pump
arm. All work together to maintain a constant metering speed to provide consistent
volumes of stain, buffer, and rinse, even though the line voltage may fluctuate. The
amount of solution pumped is electronically adjusted through the use of the volume
control knobs.

Pump Tubing and Cannulas
CAUTION
Use only the Hematek Pump Tube Set with the Hematek Slide Stainer. Use of other tubing
may result in incorrect measurement and improper staining, buffering, and rinsing.
The pump tubing is provided as a set of three separate pieces of tubing. Notice that each
pump tube is identified with a number and symbol, which corresponds to the reagent
carried by the tubing:
1 for stain
•
2 for buffer
•
•
3 for rinse
Each tube has a clear plastic cuff that fits snugly up to the pump arm and holds the tube in
position without slippage. The tubing is a special type of rubber that is resistant to
leaching and brittleness. The special diameters and lengths of the tubing assure precise
measurement of solutions. Each pump tube is connected to a cannula that is inserted into
the appropriate bottle in the Stain Pak. Three cannulas are provided with the Hematek
Slide Stainer. With proper routine cleaning, the cannulas can be used for an extended
period of time.
Section 1: Introduction, Page 1—9
Page 16
Sensing Switches
The sensing switches are three finger-like devices located just above the back edge of the
platen. When contacted, the respective sensing switch is activated, which tells the
instrument that a slide is in position for the pump to run. After a specific time delay, the
pumping motor for the specific reagent is activated. The solution pumps are set so that
precise volumes of stain, buffer, and rinse are delivered to their respective areas on the
platen. Each reagent is delivered through its respective cannula and tubing network to the
platen orifice. The capillary space between the slide and the platen is then filled with the
measured volume of reagent.

Section 3: Operating Instructions
Following initial installation (see Section 2: Installation), the Hematek Slide Stainer is
ready for routine operation. Carefully read this section before beginning any slide staining.
General Guidelines for Optimal Staining
• Use high quality slides. Do not use slides of variable thickness. Bevel-edged slides
should not be used, as they may break in the instrument.
• Make sure the blood smears are thoroughly dry before placing on the instrument for
staining.
• Clean the stain tubing with methanol after each run, especially if the Slide Stainer is not
to be used for one hour or more.
• Keep the staining grooves and guide rails clean, as instructed in Cleaning the Platen on
page 5-3. Use only methanol to clean.
• Change the pump tubing and underplaten tubing on a routine basis. Refer to
Replacement of the Pump Tubing on page 6-7 and Replacement of the Underplaten
Tubing on page 6-11 for recommended frequency.
• Check the alignment of the sensing switch fingers, as instructed in step 5 of Check and
Correct Instrument Operation Prior to Pump Volume Adjustment on page 6-15.

smear toward the back of the instrument.
Figure 3-3. Loading the Blood Smear Slides
Stain the Smears
As the slides move along the platen, first vertically, then horizontally with the blood smear
side down, the instrument performs the following steps.
1. Three sensing switches are triggered sequentially.
Each switch senses the slide and passes the information to another switch, which
activates its respective solution pump as long as a slide is detected. The solution
pumps meter and deliver the stain, buffer, and then rinse into the capillary space
between the slide and platen.
NOTE:
If the reagents overflow, as opposed to filling the capillary space between the platen and
slide, or if you obtain improper staining results, the reagent pumps may need adjustment.
Refer to Pump Volume Adjustment on page 6-14 for more information.
2. After staining and rinsing have been accomplished, the slide is dried by a flow of air from a low velocity blower.
3. The slide is delivered into the slide drawer, ready for examination.
NOTE:
If the instrument is accidentally unplugged or there is a power failure during operation, it
may be necessary to remove the slides on the platen and reprocess them.
Page 3—6, Section 3: Operating Instructions
Page 37
Clean the Tubing after Use
If no slides are to be processed for an extended period (one hour or more), it is
recommended that the stain tubing be cleaned with methanol as described in Cleaning the
Stain Tubing and Cannula on page 5-4. Push the operating lever down to the
position to relieve the pressure against the pump tubing. You must re-prime the tubing and
the platen before processing any more slides.
Turn the Instrument Off at the End of the Day
CAUTION
Always clean the instrument after daily use. See Daily Cleaning on page 5-3. If using
frosted-end slides, it is especially important to clean the front guide rail on a regular and
frequent basis. This is because the stain may spread across the frosted portion of the slide
to the front rail. If allowed to accumulate, slide breakage may occur.

Section 4: Specimens
Overview
The Hematek Slide Stainer is designed specifically for the automatic staining of peripheral
blood smears that have been prepared on standard 25 mm x 75 mm or 1” x 3” glass slides.
Blood smears that are stained according to instructions will provide the examiner with
high quality differential staining characteristics for all cytologic blood components. See
Section 3: Operating Instructions for staining instructions.
Peripheral Blood Smears
BIOHAZARD
Wear personal protective equipment. Use universal precautions. Refer to Appendix A,
page A-1 for recommended precautions when working with biohazardous materials.
It is crucial to start with a properly prepared blood smear in order to obtain the best results
on the stained slide. The following suggestions are recommended:
• Use high quality slides that are new and thoroughly cleaned.
• Slides must be free of oil and grease.
• Do not touch the slide surfaces with the fingers or against the skin of the patient.
• Protect blank slides from moisture and high humidity, as well as contamination by
dust, flies, and other insects.
• Store the slides covered in a cool, dry place.
• Never use oxalated or heparinized blood for making blood smears.
• EDTA is the anticoagulant of choice.
• Protect blood smears from excessive heat (such as radiators and ovens), water
splatters, and high humidity.
Use the following procedure to prepare a blood smear.
1. Remove the cap from a tube of well-mixed anticoagulated whole blood. EDTA is the anticoagulant of choice.
NOTE:
Blood should be kept at room temperature prior to preparing the smear. Adaquate mixing
requires approximately 20 inversions prior to blood film preparation.
2. Place a drop of well-mixed blood near one end of a high quality slide. Hold a second
spreader slide at about a 45 degree angle and approach the drop of blood. Allow the
blood to spread almost to the width of of the slide edge. Then rapidly and smoothly
push the spreader slide to the opposite end of the slide, pulling the blood behind it.
NOTE:
The angle and speed at which the blood drop is spread determines the thickness or thiness,
and length of the blood film.
Section 4: Specimens, Page 4—3
Page 42
3. The ‘feather’ end of the blood film should be at least 1.57 cm (5/8 inch) from the opposite end of the slide to avoid extending beyond the platen surface and contact with the staining reagents.
Do not allow the smear to touch the edges of the slide as large cells tend to accumulate
there. This may mechanically effect the distribution of the cell types.
Since frosted-end glass slides limit the spreading area, extra care is needed when
preparing a blood film.
Figure 4-1. Making a Blood Smear
4. Allow the smear to dry thoroughly before staining. See Section 3: Operating Instructions for staining instructions.
After staining the slide, take the following precautions.
• Examine stained slides as soon as possible.
• Protect stained slides from direct sunlight and store them in a cool, dry place.
Page 4—4, Section 4: Specimens
Page 43
Bone Marrow Smears
BIOHAZARD
Wear personal protective equipment. Use universal precautions. Refer to Appendix A,
page A-1 for recommended precautions when working with biohazardous materials.
Many laboratories stain bone marrow smears with the same stain as is used for blood
smears. The procedure involves using the “squash” technique for smear preparation and
staining the slide once or twice on the Hematek Slide Stainer. The following procedure has
been verified as giving clinically useful staining results on bone marrow slides; however,
the stain quality is dependent upon the thickness and evenness of the bone marrow smear.
A thick smear is more likely to require a second pass through the instrument than a thinner
smear; an uneven smear will not stain uniformly.
1. Use bone marrow smears that have been prepared using the “squash” technique.
Be sure the smear is thoroughly dry before staining.
2. Place the slide onto the Hematek Slide Stainer and stain according to instructions in Section 3: Operating Instructions.
3. Remove the slide after it has been stained and examine it under high power (dry) for the
staining quality.
Do not use any oil on the slide for this examination.
4. If the slide is under-stained, place it on the slide stainer again and stain it a second time. In rare instances, a third staining may be necessary.
When using the Hematek Modified Wright Stain Pak (#4481), the bone marrow
smears must be stained twice; one pass through the instrument is generally insufficient
to produce distinct nuclear intensity. A third pass generally does not increase or
decrease the quality of the staining.
When using the Hematek Modified Wright-Giemsa Stain Pak (#4405), a single
staining is generally sufficient for most bone marrow smears. The smear may become
over stained, with the appearance of precipitate and nuclear artifacts, on slides stained
two or more times.
5. Thoroughly clean the platen after staining bone marrow slides to remove the greasy residue that can be left on the platen by the fat droplets in the marrow

Section 5: Maintenance
The Hematek Slide Stainer is a precision instrument, designed to provide trouble-free
operation with a minimum of maintenance.
BIOHAZARD
Wear personal protective equipment. Use universal precautions. Refer to Appendix A,
page A-1 for recommended precautions when working with biohazardous materials.
General Cleaning
Keep the exterior surfaces of the instrument free of dust at all times. If needed, the exterior
may be cleaned using a damp cloth and mild detergent. A small amount of methanol may
be used to clean stain from the instrument.
Daily Cleaning
It is vitally important to clean the platen and tubing at least once each day in order to
maintain consistently high quality staining results. It is also important to empty the waste
tank at the end of each day.
Cleaning the Platen
After staining a large number of blood smears, precipitated stain solution tends to
accumulate in the mixing grooves of the platen. This precipitate must be removed at
regular intervals. Daily cleaning of the platen is imperative; after each run is optimal.
Cleaning is especially important if bone marrow slides have been stained because the fat
droplets can leave a greasy residue on the platen. Use the following procedure to clean the
platen:
1. Turn the instrument off.
2. Carefully flood the working area of the platen with methanol.
Avoid splashing the methanol.
CAUTION
Always wipe the platen from right to left. Damage to the position or shape of the sensing
switch fingers may result from not following recommended cleaning practices. Check the
position of the fingers after cleaning as described in step 5 of Check and Correct
Instrument Operation Prior to Pump Volume Adjustment on page 6-15.
Section 5: Maintenance, Page 5—3
Page 48
3. After priming, wipe the platen with a soft, disposable, lint-free absorbent cloth or tissue.
Wipe from right to left only.
Figure 5-1. Cleaning the Platen
CAUTION
If using frosted-end slides, it is especially important that the front guide rail be cleaned on
a regular and frequent basis. This is because the stain may spread across the frosted
portion of the slide to the front rail. If allowed to accumulate, slide breakage may occur.
4. Thoroughly clean the mixing grooves and the front guide rail.
Cleaning the Stain Tubing and Cannula
The tubing carrying the stain should be cleaned at least once daily (or after each run), as
described in the following procedure:
1. Remove the stain, buffer, and rinse cannulas from the Stain Pak bottles.
NOTE:
The buffer and rinse cannulas and tubing do not require cleaning. These cannulas are
removed so the buffer and rinse solutions are not wasted while the stain tubing is being
cleaned.
Page 5—4, Section 5: Maintenance
Page 49
2. Using the prime function, purge the stain from the tubing.
a. Place the stain cannula, with tubing attached, into a small container of methanol
and lift the operating lever to
Figure 5-2. Rinsing the Stain Tubing
PRIME.
b. Holding the lever in this position, continue to pump methanol through the stain
tubing until it is thoroughly rinsed and clear solution appears on the platen.
3. After the stain tubing has been cleaned, remove the cannula from the methanol and continue to prime until the tubing is emptied of all methanol
CAUTION
Always wipe the platen from right to left. Damage to the position or shape of the sensing
switch fingers may result from not following recommended cleaning practices. Check the
position of the fingers after cleaning as described in step 5 of Check and Correct
Instrument Operation Prior to Pump Volume Adjustment on page 6-15.
4. Carefully wipe the platen with a soft, disposable, lint-free absorbent cloth or tissue.
Wipe from right to left only.
Section 5: Maintenance, Page 5—5
Page 50
Emptying the Waste Tank
Empty the waste tank once each day, as well as after installing a new Stain Pak. To avoid
spilling the contents while emptying the waste tank, carefully pull the tank away from the
instrument, supporting the bottom of the tank to hold it level during removal. After
emptying into an appropriate receptacle, rinse the waste tank with water and reinstall it
into the instrument.
Figure 5-3. Removing the Waste Tank
Weekly Cleaning
Clean the drain troughs and the rear guide rail on a weekly basis.
Cleaning Drain Troughs and Rear Guide Rail
The back and front drain troughs of the stainer function as drains for excess stain, and
residues from the reagents that may accumulate and interfere with proper drainage. The
recommended procedure for proper cleaning is as follows:
1. Turn the instrument off and remove the line cord from the AC electrical outlet.
2. Raise the lid of the instrument.

New tubing is sometimes difficult to prime the first time and may need assistance. While
holding the operating lever in the
PRIME position, push the pump arm inwards (toward the
pump) until the reagent fills the tubing, then release the pump arm. It may also be helpful
for you to pinch the tubing several times with your fingers, pinching in the area between
the cannula and the pump arm.
12. Verify the pump timings and reset the volume controls if necessary. See Pump Volume Adjustment on page 6-14.
Replacement of the Underplaten Tubing
The underplaten tubing is the tubing between the spout under the platen and the nipple
behind the circuit board. The buffer and rinse tubing should be replaced after
approximately ten Stain Paks have been used. The stain tubing needs to be changed more
frequently, especially if it is not regularly flushed with methanol. Depending on usage and
cleaning patterns, the stain tubing may need to be changed as often as after every four
Stain Paks. Use the following procedure to replace the underplaten tubing with new tubing
in the Hematek Underplaten Tubing pack (Product No. 4484).

Pump Volume Adjustment
The Hematek Slide Stainer is designed to produce stained slides of consistent quality in a
continuous process. This is accomplished by having a fixed length of time in each of the
three phases of stain, buffer, and rinse, as well as a predetermined ratio of stain-to-buffer
volumes in the buffer phase.
The stain-to-buffer ratio is adjustable to provide ratios of at least 1:2 to 1:3. This feature
allows the user flexibility in obtaining the desired stain results. A small change in the
stain-to-buffer ratio can result in either lighter or darker staining. The amount of
reagent pumped in each of the three phases is adjustable through the use of the volume
control knobs located in the front control panel.
Page 6—14, Section 6: Minor Replacements and Adjustments
Page 69
Check and Correct Instrument Operation Prior to Pump Volume Adjustment
Follow these steps to check and correct instrument operation when slides are not
satisfactory or pump volumes do not appear to be optimum. If any of these steps correct
the situation, you do not need to adjust the pump volumes.
1. Replace both sets of tubing.
Refer to Replacement of the Pump Tubing on page 6-7 and Replacement of the
Underplaten Tubing on page 6-11.
2. Clean the platen, including the front and back drain troughs, and make sure that there is no residue in any mixing groove.
Refer to Cleaning the Platen on page 5-3 for instructions to clean the platen and the
drain troughs.
3. Observe the circular bubble level to make sure the instrument is level to provide optimal buffer mixing.
If leveling is required, follow the Level the Instrument on page 2-4.
4. Make sure the Stain Pak has been vented.
Refer to Install the Stain Pak on page 2-9.
5. Check the adjustment of the sensing switch fingers.
6. Observe several slides as they move across the platen and visually ensure all of the following events occur and they are activating the pumps at the proper time.
• The stain pump should be activated after approximately ½ of the slide width has
passed over the stain orifice.
• The buffer pump should be activated after about 1/8 inch of the slide has crossed
over the buffer orifice.
• The rinse pump should be activated just as the leading edge of the slide crosses over
the rinse orifice.
7. If the starting times for each phase are not correct, follow the procedure in this section.
Adjust the Stain, Buffer, and Rinse Volumes
Optimal staining results are achieved when the Hematek Slide Stainer is properly adjusted.
Normally, proper adjustment of the instrument can be determined by observation of the
amount of stain and buffer required to fill the capillary gap between the slide and the
surface of the platen. If the proper amounts of stain and buffer are being pumped, proper
mixing of the reagents will occur, resulting in uniform staining of blood smears. Use the
following procedure to adjust the pump volumes.
1. Locate the pump volume control knobs, which are located in the control panel on the front-right corner of the instrument.
Each knob contains a centering catch on, which provides a central reference point.
The instrument is manufactured to give a stain-to-buffer ratio of approximately 1:2.5
and a rinse volume of approximately 1.0 mL/slide when each knob is at the centering
catch.
Section 6: Minor Replacements and Adjustments, Page 6—15
Page 70
Volume is lowest when a knob is turned fully counterclockwise and highest when
turned fully clockwise.
Volume increments are marked on each knob:
• Stain and buffer knobs: Each evenly labeled increment changes the volume by
approximately 0.1 mL per 10 slides (0.01 mL/slide).
• Rinse knob: Each evenly labeled increment changes the volume by approximately
0.5 mL per 10 slides (0.05 mL/slide).
2. Prime the instrument by placing the operating lever in the
PRIME position and holding
it there until solution is being pumped at all three stations (stain, buffer, and rinse).
3. Wipe the platen after priming, wiping from right to left only.
4. Prime the platen by loading five priming slides and allowing them to be transported across the platen.
This procedure primes and wets the platen to achieve proper surface tension
characteristics.
5. Adjust the stain volume as follows:
a. Run five blood smear slides across the platen immediately following the priming
slides.
b. Adjust the stain control knob so the stain just fills, but does not overfill, the
capillary space between the platen and the slide.
c. If the slide is receiving an inadequate amount of stain, adjust the control knob
clockwise.
d. If overflow of solution is visible on either side of the slide or an excess of stain is
visible hanging over the front beveled edge of the platen, adjust the stain control
knob counterclockwise.
The adjustment is correct when proper fill has been achieved on two consecutive
slides.
6. Adjust the buffer volume as follows:
a. If there has been a gap of more than two consecutive slides across the platen since
the stain volume adjustment, re-prime the platen with three priming slides.
b. Run five blood smear slides across the platen immediately following the priming
slides.
When the slide passes the buffer section of the platen, mixing of the stain and buffer
occurs because of the mixing grooves. This is where the proper stain-to- buffer ratio is
most important. The slide looks under filled as it travels over the mixing grooves
because the capillary gap is slightly greater.
7. Adjust the buffer control knob so the stain-buffer mixture just fills the capillary space under the slide when the slide is past the mixing grooves and onto the smooth portion of the platen, just before the rinse area.
Ensure that the stain-buffer mix does not extend out from either side of the slide.
Page 6—16, Section 6: Minor Replacements and Adjustments
Page 71
NOTE:
As the slide moves along, the buffer should pulse from the buffer orifice and move around
the two mixing grooves for complete mixing of the stain and buffer. Too much stain and/or
buffer will reduce the pulsing action, causing inconsistent staining across the slide. If
partial flooding occurs, it should quickly re-drain as the slide continues to move across the
grooves. Complete flooding of the second groove may indicate an excessive volume of
either the stain or buffer.
8. Adjust the rinse volume as follows:
a. Examine the slides under a microscope.
b. If adjustment is necessary, use the rinse control knob to make the correction.
c. If excess stain is left on the slide appearing as precipitation under the microscope,
increase the rinse volume.
d. If the staining is pale due to over washing, reduce the rinse volume.
NOTE:
Any change in the rinse setting may cause a slight color change due to the small amount of
methanol in the rinse.
9. Recheck the adjusted pump volumes:
a. Prime the platen with three priming slides.
b. Run at least three blood smears to ensure that the capillary spaces between the
platen and slide fill completely with stain at the stain area and with stain-buffer
mixture just before the rinse area.
NOTE:
Occasional small voids may occur on the slide after proper filling. These voids are
acceptable and will not adversely affect stain quality. Do not try to compensate for small
voids by increasing the stain volume. Doing so may upset the optimum stain-to-buffer
ratio and may affect the stain intensity.
Volume and Ratio Determination
Once adjustments have been made that appear visually to be giving appropriate slide
results, the pump volumes and stain-to-buffer ratio can be measured as follows:
1. Remove the waste tank and disconnect the underplaten tubing leading to the stain, buffer, and rinse spouts on the platen.
2. Place the tubing ends into a beaker or other small container, and prime by using the operating lever.
3. As soon as all three-pump tubes have been primed and are free of air, place the free end of the stain and buffer tubes into separate 10 mL graduated cylinders. Place the free end of the rinse tube into a 25 mL graduated cylinder.
4. Process 10 blank slides and record the volume of stain, buffer, and rinse solution pumped into each cylinder. The following should be noted:
Section 6: Minor Replacements and Adjustments, Page 6—17
Page 72
The stain-to-buffer ratio should be approximately 1:2 to 1:3, (i.e., the volume of buffer
should be about 2 to 3 times that of the stain).
Example:
1.6 mL of stain per 10 slides = 0.16 mL/slide
4.1 mL of buffer per 10 slides = 0.41 mL/slide
0.41 ÷ 0.160 = a ratio of 1:2.56 between stain and buffer
The rinse volume should be approximately 10 mL for the 10 slides.
A properly stained slide is the result of an interactive process involving the pump
volumes, the mixing process, and the stain-to-buffer ratio. A minimum ratio of 1:2 is
recommended; however, if the platen is filling properly, good mixing is occurring, and
the stained slides are acceptable under the microscope, the stain-to-buffer ratio should
not be adjusted.
5. When the determinations are complete, reconnect the three tubes to their appropriate spouts and replace the waste tank.
Sensing Switch Fingers Adjustment
The sensing switch fingers must be properly positioned in order to accurately activate the
reagent pumps. If the reagents are not being dispensed, check the location of the fingers.
Not following recommended cleaning practices may force the sensing switch fingers out
of adjustment. Use the following procedure to adjust the sensing switch fingers.
1. Turn the instrument off and remove the line cord from the AC electrical outlet.
2. Raise the clear plastic lid on the instrument.
3. Loosen the two thumbscrews that are inserted through the notches in the back of the circuit board cover.
Figure 6-17. Location of Thumbscrews
Page 6—18, Section 6: Minor Replacements and Adjustments
Page 73
4. Carefully rotate the panel up and back.
The circuit board cover is connected to the instrument by the two connectors of the
LOW STAIN and POWER lights. Rotate the panel carefully so the connectors are not
pulled loose.
5. Check the location of each of the sensing switch fingers for the following two criteria:
Each finger should point straight down into the center of the back trough of the platen,
without touching the bottom.
If it is not, bend the finger slightly forward or backward as necessary, as directed
below.
The sensing switch should be activated before the finger is lifted over the top surface
of the slide.
6. Lay a slide lengthwise along the back edge of the platen and slowly push the slide from right to left past the sensing switch finger, listening for a slight click as the sensing switch is activated.
If the click is not occurring before the finger has been lifted onto the top of the slide,
bend the finger slightly to the right, as directed below.
Figure 6-18. Checking for Adjustment of Sensing Switch Fingers
Section 6: Minor Replacements and Adjustments, Page 6—19
Page 74
7. If adjustment to a sensing switch finger is necessary, support the wire near the center and carefully bend the lower part of the wire.
If bending to the right, bend the wire no more than 7 mm (1/4 in.) past perpendicular.
Figure 6-19. Adjusting the Sensing Switch Finger
8. Verify the final adjustment of each of the sensing switch fingers by processing several slides across the platen as in Step 5 of Check and Correct Instrument Operation Prior to Pump Volume Adjustment on page 6-15.
If these adjustments do not result in correct timing, contact your local technical support
provider or distributor.

Section 7: Troubleshooting
The Hematek Slide Stainer is designed to give trouble-free operation when the directions
for operating and cleaning the instrument are followed. If a problem occurs, refer to
troubleshooting pointers in this section for help in solving the problem.
Checklist for Quality of Stained Blood Smears
When stained blood smears do not have the desired quality, the first tendency is to assume
the staining reagents or the stainer is at fault. Frequently, however, other factors are the
cause of the poorly stained blood smears. The following checklist can help isolate the
problem when you question the quality of stained blood smears.
Are the pump volumes properly adjusted? Improper settings may lead to poorly
stained blood smears.
Is the blood old or does it contain an incorrect anticoagulant? Use fresh blood
(less than 8 hours old), EDTA is the anticoagulant of choice.
Was the blood thoroughly mixed before making the smear?
Is the blood smear too thick, too thin, or spread unevenly?
Does the feathered edge of the smear end at least 1/8 inch from the end of the
slide?
Was the blood smear thoroughly dry before staining?
Are the slides clean? Even new slides are not necessarily clean.
Are the slides flat? Variable thickness of a given slide may cause uneven staining.
Have the Hematek Stain Pak containers been vented? Venting is necessary for
even delivery of the stain, buffer, and rinse reagents.
Has the reagent tubing on the Hematek Slide Stainer been primed before staining
the slides? Air bubbles in the tubing will cause poorly stained smears.
Has the platen been primed and wetted before running blood smears? Process two
to four blank slides across the platen to wet the platen surface before each run of
blood smears.
Is the stain tubing, cannula, nipples, or orifice plugged? Daily cleaning of the stain
tubing is recommended to prevent plugging.
Are the platen and grooves clean and free of residue? A dirty platen or grooves
will result in uneven, low-quality staining.
Is the microscope clean and adequately illuminated? A dirty microscope or
inadequate lighting may give the impression of a poorly stained blood smear.
