1 Product description
1.1 Features
The Research plus pipettes are piston-stroke pipettes that operate according to the air-cushion
principle.
When the control button is pressed, the piston in the pipette moves in the same direction. If the
1
control button and the piston are moved upwards, the liquid can be aspirated into the pipette tip.
With the downward movement of the piston, the liquid is dispensed (measuring stroke).
Blow-out occurs if the downward piston stroke exceeds the first stop.
Depending on the Research plus pipette it is possible to dispense volumes from 0.1 L to 10 mL.
The Research plus family consists of single-channel and multi-channel pipettes (8 and
12-channels) with variable volume settings, as well as single-channel fixed-volume pipettes. You
can find a list of all available models of the Research plus in the "Technical Data" section.
All Research plus pipettes are fully autoclavable.
You can adjust the Research plus pipettes. The side viewing window displays the change in the
adjustment.
When attaching a pipette tip, the spring-loading action of the tip cone is activated (exceptions
5 mL and 10 mL pipettes).

3.2 Using pipette tips
The liquid to be dosed is aspirated into pipette tips. It is recommended to use epT.I.P.S. The
epT.I.P.S. pipette tips are available in different purities, as tips with and without a filter and as
special tips. When using liquids whose surface tension is lower than that of water (e.g., due to the
presence of a wetting agent in the liquid), the use of the special tips epT.I.P.S. LoRetention is
recommended.
Operation
required value and then back again.
The pipette is only functional if a pipette tip has been
attached. You can either attach the pipette tip by hand or
directly insert the end of the pipette into a tip held in the tip
storage box. If attaching a pipette tip by hand, it must be
handled in such a way to avoid contamination and heating of
the pipette tip.
The color of the control button of the Research plus matches
the color of the epT.I.P.S. tray.
If you are using pipette tips without a filter, insert the
protection filter into the 5 mL and 10 mL pipettes.
If you are using the 5 mL or 10 mL epDualfilter T.I.P.S.,
remove the protection filter in the pipette. This also
applies to 5 mL / 10 mL filter tips of other manufacturers.
The filters can interfere with each other. The
backpressure of the two filters makes it difficult to exactly
identify the first stop (see p. 11).
Fit the suitable pipette tip(s) on the tip cone, applying light
pressure.
The pipette tip is securely attached to the tip cone when
it responds with spring-loaded action (exceptions: no
spring-loading action for 5 mL and 10 mL single-channel
pipettes)
You can deactivate the spring loading action of the tip cone in
the case of single-channel pipettes (see p. 17).

3 Operation
3.3 Aspirating liquid
1. The liquid to be aspirated must be taken from a suitable vessel. For
multi-channel pipettes, we recommend the reagent reservoir "Tip-Tub".
2. Press down the control button to the first stop (measuring stroke).
3. Immerse the pipette tip(s) vertically approx. 4 mm into the liquid.
4. To aspirate liquid, allow the control button to slide back slowly. Maintain the
immersion depth, so that no air is aspirated accidentally.
5. In the case of large volumes: before removing the pipette tip from the liquid,
wait for approx. 3 seconds. To ensure maximum precision and accuracy, we
recommend to wet each new tip initially by aspirating and dispensing the
liquid one to three times. Only then should pipetting commence.
6. Remove the tip(s) slowly from the liquid.
7. Wipe the tip(s) slowly against the tube wall to ensure that no outer wetting
remains on the tip.
3
3.4 Dispensing liquid
1. Place the tip(s) on the tube wall at an angle.
2. Press the control button slowly until the first stop (measuring stroke) and
wait until the flow of liquid stops.
3. To empty the tip(s) completely, press down the control button until the
second stop (blow-out).
4. Hold down the control button and wipe the tip(s) against the tube inner wall.
5. Let the control button slide back slowly outside of the tube.

4 Troubleshooting
To avoid dispensing errors, check the precision and accuracy of the Research plus at regular
intervals. The "PICASO" program (from Version 2.3) is available to determine the permitted
measured systematic and random errors. If the pipette is used at an extremely high location, it
must be adjusted to the ambient air pressure. A SOP (Standard Operation Procedure) for
checking pipettes can be found on the Research plus CD and on our website
www.eppendorf.com

compatibility and check the manufacturer's instructions about chemical resistance.
Consider also the material of the pipette.
5.2.1 Autoclaving
All Research plus pipettes are completely steam autoclavable.
Before autoclaving
1. Remove any contamination from the exterior and in the lower part (see Research plus
disassembly and assembly on p. 17).
2. If you remove existing grease, slightly relubricate the piston seal using only the grease
specified in the ordering information (see the enclosed CD).
Procedure
Follow the operating manual of the autoclave manufacturer.
1. Autoclave at: 121°C; 20 minutes; 1 bar overpressure
2. When placing the Research plus into the autoclave, make sure that the temperature at the
pipette does not exceed 121°C.
3. You can put the Research plus into the autoclave as a whole unit or with the lower part
removed. Do not disassemble the lower part.
4. For 5 mL and 10 mL pipettes: remove the old protection filter. Add a new protection filter and
install it after autoclaving. Autoclave the protection filter only once.
5. If lower parts have been removed, make sure that no lower parts are confused during
reassembly. (Tip: Use one plastic beaker per pipette).
After autoclaving
Cool the pipette down to room temperature and leave to dry.
For 5 mL / 10 mL pipettes: the protection filter swells during autoclaving. Slightly compress
the protection filter when inserting it into the tip cone.

Deactivating the spring-loading action: installing the locking ring
For the following dispensing tasks it can be helpful to deactivate the spring loading action of the
tip cone.
• A pipette tip is to be used for a long period.
• The pipette tip is slightly bended during dispensing.
Deactivating this action can also be helpful for pipette tips which are not designed for the
Eppendorf pipette tip cone.
The spring loading action of the tip cone can be deactivated by installing
the locking ring. The locking ring is included in the delivery package.
1. Push the black locking ring onto the lower part from the top. Slightly
squeeze the clamps on the lower part when doing so.
2. Insert the lower part into the upper part until it engages audibly.
3. Keep the ejector pressed. The ejector rod protrudes from the upper
part.
4. Fit the ejector sleeve onto the ejector rod. It is fitted correctly if it
engages slightly.

5.5 Adjusting pipettes
NOTICE! Incorrect dispensing volume for special liquids and from temperature
differences.
NOTICE!
Solutions which differ greatly from water in terms of their physical data, or temperature
differences between the pipette, pipette tip and liquid can result in incorrect dispensing
volumes.
Maintenance
Avoid temperature differences between pipette, pipette tip and liquid.
Make sure that the temperature is constant, between 20 and 25°C and at ±0.5°C.
Check the dispensing volume and readjust the pipette in case of deviations.
The systematic and random errors recorded on delivery can be found in the Certificate
Hint!
of Conformity. This certificate is included in the delivery. Changes to the factory
adjustment will render the certificate void.
5.5.1 General notes on user and factory adjustment settings
The Research plus was adjusted, tested and fitted with a gray adjustment seal with the
abbreviation "ADJ" before delivery. The adjustment display on the side reads "0".
Changing the adjustment of the Research plus is sometimes recommended for solutions which
are very different from water with regard to their density, viscosity, surface tension and/or vapor
pressure etc. If the density of an aqueous solution changes by approximately ±10%, for example
because of the salt concentration, the volume changes by approximately ±0.2%. This statement
does not apply if other relevant properties of the liquid also change.
If the pipette is used at extremely high altitudes, it must be calibrated to the ambient air pressure.
At 1 000 m above sea level, the volume error of a 100 L pipette is about –0.3%.
When using special tips, that is, tips that significantly differ from standard tips in their geometry,
changing the adjustment can improve the dispensing accuracy (systematic error). The CD
Research plus contains adjustment tips for epT.I.P.S. long.
Adjustment changes can be reset by simple steps.
In addition to changing the user adjustment, a Research plus with variable volume setting can be
permanently changed by altering the factory adjustment (see Changing the factory adjustment
on p. 25).
Changes made to the user or factory adjustment do not affect dispensing precision (random
error). Precision can be improved by exchanging worn parts. Precision is also considerably
affected by handling.
Before changing the adjustment or factory calibration, you must check the existing dispensing
volume.
The actual volume can be checked by weighing:
22
Page 23
Eppendorf Research® plus — Operating manual
5 Maintenance
The density of distilled water is approx. 0.9982 mg/L at 20°C and 0.9965 mg/L at 27°C.
If the set volume corresponds to the actual volume, no correction is necessary.
If there is a difference between the actual volume and the set volume of distilled water, please
check the following:
• Is there any liquid dripping from the tip?
• Is the pipette tip fitted leak-proof?
• Is the tip cone undamaged?
• Are the piston and the cylinder leak-proof?
Adequate leak tightness is ensured when no drop is formed at the pipette tip after aspiration
of the nominal volume with distilled water and a waiting time of approx. 15 s. Hold the pipette
vertically, making sure not to touch the pipette tip. Prewet the tip several times in the case of
nominal volumes ≤ 20 L.
• Does the temperature of the pipetted liquid correspond to:
– the temperature of the device?
– the ambient air temperature?
• Is the weighing location free from drafts?
• Does the work method and pipetting speed permit complete aspiration and dispensing of the
liquid?
• Has the correct numerical value for "Density liquids at weighing temperature" been used for
the calculation of the actual volume?
• Is the set volume correct?
• For very small volumes (<10 L): is the fine balance sufficiently sensitive (balance resolution:
0.001 mg)?
• Were original epT.I.P.S pipette tips used for testing?
Information as to which pipette tip must be used as a test tip for checking the technical data
can be found in the "Technical Data" chapter of the operating manual.
No adjustment changes are allowed unless you can answer all the questions with "yes". In all
other cases, the problems associated with the questions answered with "no" must be eliminated.
If the problem is remedied by exchanging a complete lower part or other parts that have an effect
on the volume, proper assembly must be verified by carrying out a gravimetric test. Information
on the systematic and random errors to be met can be found in the "Technical Data" chapter.

5.5.2 Changing the user adjustment
If the adjustment is changed, the volume changes by a certain value. Strictly speaking, the
change only applies to the testing volume.
Auxiliary equipment
• Supplied adjustment tool (order no. 3120 633.006)
• Supplied red adjustment seal (ADJ)
Example
You readjust a 10 -100 L pipette with a volume setting of 100 L by 1 L (1 L 1%). If the
Maintenance
volume setting is 10 L, the pipette is also adjusted by 1 L ( 10%).
1. Remove the gray adjustment seal.
2. Keep the ejector pressed.
3. Insert the adjustment tool (from the delivery package).
4. Turn the adjustment tool until the adjustment display shows the desired value.
5. Place the Research plus on a horizontal surface
(table). When completing the adjustment, look
absolutely vertically at the window and read the set
value via the backsight in the viewing window.
6. Carry out weighings to verify accuracy and precision.
7. After the tests, close the opening with the red adjustment seal (from the delivery package).
If the adjustment is meant for a specific liquid, mark the pipette accordingly. Use the labeling area
on the pipette for this purpose and write down the liquid and the volume. Carry out a gravimetric
test for each adjustment change. Follow the test procedures of EN ISO 8655-2 and 8655-6. A
SOP (Standard Operation Procedure) and further information on user and factory adjustment
settings can be found on the Research plus CD and on our website www.eppendorf.com

5.5.3 Changing the factory adjustment
Auxiliary equipment
• Supplied safety plug tool
• Supplied pin to loosen the safety plug
It is possible to change the factory adjustment with the
corresponding accessories for a Research plus with variable
volume setting. If the factory adjustment of the Research plus has
been changed by a user, this can be recognized by a red safety
plug behind the ejector. If the Research plus has been adjusted and
calibrated by Eppendorf AG, this is indicated by a gray safety plug.
The systematic and random errors recorded on delivery can be found in a "Certificate of
Conformity". This certificate is included in the delivery. Changes to the factory adjustment will
render the certificate void.
If the dispensing accuracy is only be to changed temporarily, the correct method is to change the
user adjustment. Before changing the user or factory adjustment, observe the general notes
(see General notes on user and factory adjustment settings on p. 22) and the associated
gravimetric tests.
In the case of Research plus fixed-volume pipettes, modifications are only possible by
Hint!
changing the user adjustment (see Changing the user adjustment on p. 24).
5.5.4 Research plus variable - changing the factory adjustment
If a gravimetric test indicates that an error needs to be corrected and you are required to carry out
a change to the factory adjustment, proceed as follows:
1. Check whether the adjustment display on
the side is set to "0".
If the adjustment display is not set to "0",
you will first need to set it to "0" with the
adjustment tool. In this case, instead of
continuing with the factory adjustment
changes, carry out a gravimetric test of the
Research plus with the adjustment display
set to "0".

The values mentioned are theoretical values and are for orientation purposes only. The
volume changes mentioned apply to each volume setting. For the volume change, you
should first set the optimal value for 10% of the nominal volume and then carry out a
gravimetric test. Afterwards carry out gravimetric tests to check 50% and 100% of the
nominal volume with this setting. Change the selected setting again if necessary to achieve
the best possible correction for all volumes. Use the error limits in accordance with ISO
8655-2 (see p. 31) and the technical data provided by Eppendorf AG (see p. 35) to decide
