1. Biohit eLINE electronic pipettors

The Biohit eLINE electronic pipettors offer you the latest technology and innovations in the field of the hand held liquid handling devices. The attractive and ergonomic design of the eLINE pipettors together with electronic tip ejection operation take the effort out of pipetting and reduce the risk of repetitive strain injuries (RSI) that are common in mechanical pipetting.

The microprocessor controlled system and the superior construction of the Biohit eLINE pipettors enables maximum liquid handling performance with high levels of accuracy and precision. The microprocessor controlled piston movements reduces the possibility of human error and thus also contamination of the pipettor interior. The tip cone design of the Biohit eLINE pipettors offer the possibility to use replaceable Safe-Cone Filters to help prevent contamination and damage of the pipettor.

The eLINE electronic pipettors offers a comprehensive range of liquid handling protocols, typically required by laboratories currently. The simple keyboard and easy-to-read display together with user-friendly operation and programming allows these tasks to be performed quickly and effortlessly. The Biohit eLINE pipettors operate on the air displacement principle and use disposable tips.

3.2. Reset Button

To reset the pipettor, press the reset button on the battery cover. The display shows RESET and PRESS TIP in a blinking form and pressing the tip ejector button will reset the pipettor to the first programming level in PIPET mode.

During the reset function the pipettor automatically determines the home position for the piston and tip ejector by running the piston up and down. During the reset function the display shows AUTO TEST and the completed reset function is confirmed by showing the text DONE on the display.

Note: The pipettor must never be reset with the tip attached! The attached tip can induce an error in home position determination. However, if resetting is accidentally done with the tip attached reset the pipettor again without the tip attached.

3.3. Start Button

The start button triggers the aspiration and dispensing operations according to selected operating mode. Only a soft touch is required to operate the button. If the start button is held down during dispensing, the piston will stop in the lowest position until the button is released. In the operating modes with automatic blow-out (P, dd) the piston will automatically return to the home position after the start button is released.

If the start button is held down in the reverse pipetting mode or during the dispensing of the last aliquot in the multi-dispensing modes the piston direction symbol will change within one second and the pipettor will be ready to aspirate the next sample when the start button is released.

3.4. Tip sealing and Electronic tip ejection

The Biohit pipettor tips are recommended for use with Biohit

LINE pipettors. The eLINE multichannel pipettors are provided with a spring loaded OPTILOAD tip cones for optimal sealing.

For easy and effortless tip ejection all Biohit eLINE electronic pipettors are equipped with the new electronic tip ejection feature (Fig. 2). There are two tip ejection buttons conveniently placed on the either side of the start button to ensure easy reach for both right and left handed users. In singlechannel models the tip ejector collar can be adjusted to optimise the tip ejection function when other than manufacturer’s original tips are used (excluding the e5000).

Fig. 2.

Tip ejection: When the pipetting cycle is completed, either of the buttons can be depressed to eject the tip.

Note: The tip ejection function is frozen during the pipetting cycle and can only be activated after the tip is emptied. If needed the pipetting cycle can be interrupted by pressing the enter button. The display will show E (E=empty) and the tip is then emptied by pressing the start button.

Adjusting the tip ejector collar (excluding the e5000): The tip ejector collar can be adjusted by unscrewing the collar anti-clockwise until the collar almost touches the attached tip. The adjustment range is 4 mm.

Note: The e5000 model is equipped with an inner tip ejection mechanism and does not have an adjustable tip ejector collar.

3.5. Biohit Safe-Cone Filters

The tip cone design of the Biohit

LINE pipettors (>10 µl) allows the use of Biohit Safe-Cone Filters in the tip cones. These removable filters prevent liquids and liquid vapours from entering the pipettor and thus protects the pipettor from cross contamination and damage.

The Safe-Cone Filters are available as Standard or Plus versions. It is recommended to use the Standard Filter for general applications and the Plus Filter for more demanding applications. The filters need to be changed regularly. The interval for filter changing is application dependant but the recommendation is to change the filter daily (after 50 – 250 pipetting cycles) and always in case of over-aspiration. The Biohit Filter Forceps should be used to avoid touching the soiled filters by hand (Fig. 3). (See Chapter 1.1. for ordering information.)

9. Pipetting recommendations

The wide selection of different operating modes makes is possible to perform several different liquid handling tasks with BiohiteLINE pipettors. The operating modes P, P+MIXING, P COUNT, dd, dd+MIXING and SA feature an automatic blow-out and others leave an excess liquid in the tip. The user should follow the recommendations below to ensure optimal performance.

9. 1. Dispensing with blow-out

The automatic blow-out function, in different pipetting and diluting modes, is followed by an immediate return of the piston to the home position. To avoid accidental aspiration of the liquid back into the tip, it is recommended that the dispensing is always performed above the liquid surface.

By holding the START button down during dispensing the piston will stop in the lowest position. This allows the tip to be placed under the liquid surface or against the bottom or the wall of the container during dispensing. Once the liquid is dispensed, the tip can be removed from the container and the START button released.

9.2. Dispensing without blow-out

The pipettor will not perform the blow-out function in modes rP, P MANUAL, d, Ad, and Sd. Therefore it is recommended that dispensing in these modes is

always performed with the tip set against the wall or bottom of the container.

9.3. Other recommendations

- Hold the pipettor vertically when aspirating the liquid and place the tip only a few millimetres into the liquid.

- Pre-rinse the tip before aspirating the liquid by filling and emptying the tip for three to five times. This is important especially when pipetting liquids with a viscosity and density greater than water.

- Check that the pipettor, tip and liquid are at the same temperature.

- To avoid the contamination, do not rest the pipettor on its side especially when the tip attached.

- Change the tip cone filter regularly.

- Always place the pipettor in the charging unit when not in use.

- Never strike the tip cone against the tip tray when mounting the tips as this can damage several internal components.

- Do not use excessive force when mounting the tips as this can hamper the tip ejection.

- Avoid rough handling, light pressure is all that is required when using the keyboard or mounting the tips.

- Do not drop the pipettor or charging unit as this may cause excessive shock.

- Avoid exposing the unit to extreme temperature changes, humidity and dust (operating temperature from 15

C to 40OC and maximum humidity

80%).

10. Maintenance

To ensure trouble-free operation it is recommended to apply regular maintenance and cleaning to Biohit eLINE electronic pipettors.

Note: Remove the battery pack from the pipettor prior to servicing!

It is recommended always to use gloves when cleaning the pipettor. Change the tip cone filter regularly with the tool provided.

10.1. Cleaning the outer surface of the pipettor

To clean and decontaminate the outer surface use Proline

Biocontrol (Cat.no. 724004, 5 litres) and a soft lint-free cloth. Gently clean the surface of the pipettor with moistened cloth and wipe dry. It is also possible to use ethanol (70%) isopropanol (60%) or a mild detergent as a cleaning agent.

holder (3), tip cone (4) and spring (5). Remove the tip cone filter if fitted.

4. Unscrew the exposed piston (6) anti-clockwise and remove it. Cleaning:

To clean the exposed parts use Proline

Biocontrol, ethanol (70%), isopropanol (60%) or mild detergent and soft lint-free cloth. The interior of the tip ejector collar and tip cone can be cleaned with a cotton swab. Rinse with distilled water if needed. Let the parts dry. Grease the piston thinly with the grease provided.

Decontaminate: For complete decontamination place the

tip ejector collar (2), tip cone holder (3), tip cone (4), spring (5) and piston (6) into a beaker containing Biohit Proline

Biocontrol and leave for at least 30 minutes (Fig. 9), rinse the parts with distilled water.

Note: The corresponding parts in the e5000 model are the green tip cone (4), the black tip ejector assembly and the piston (6).

Let the parts dry . Gr ease the piston thinly with the grease provided.

Fig. 9.

Autoclaving: The tip ejector collar (2), tip cone holder (3), tip cone (4), spring (5) and piston

(6) of the

eLINE pipettor can be steam autoclaved (121

C, 1 bar overpressure for 20 minutes), see Fig. 8. These parts can be autoclaved as one unit or separately as individual parts. It is also possible to clean the parts and grease the piston prior to autoclaving.

Note: The autoclavable parts in the e5000 model are the green tip cone (4), the black tip ejector assembly and the piston (6).

Note: Avoid excess grease. Use only the grease provided with the pipettor.

Note: Before reassembling check that no lint or particles are on the surface of the piston.

Reassembling: 1 . Screw the piston (6) clockwise into position.

2. e10, e120, e300, e1000: Place the spring (5) around the piston. e5000: Attach the green tip cone by screwing it clockwise. Place the tip

ejector assembly to the tip cone and attach by turning it clockwise. Replace the tip cone filter with the tool provided and continue from Step

3. Push the tip cone (4) into position and attach it by screwing the tip cone holder (3) back. Replace the tip cone filter with the tool provided.

4. Attach the tip ejector collar (2) by screwing it clockwise.

5. Replace the battery pack (1). Reset the pipettor and press the start button several times to test the movement. Test the tip ejection operation.

Note: When reassembling the pipettor do not over tighten the parts.

Note: It is always necessary to check the performance of the pipettor after inhouse service or maintenance (see paragraph 11).

10.3. Battery replacement

The design of the Biohit

LINE pipettors enables fast and easy battery replacement. The battery replacement pack includes 4 NiMH batteries fixed to the battery cover. If the batteries do not hold a sufficient charge for proper operation follow these steps for replacement of the battery pack.

Note: The battery pack fits in to the compartment one way only. If the pack is inserted incorrectly the battery cover will not close properly.

Note: Only use battery packs supplied by the manufacturer. The use of any other type of battery will immediately invalidate the warranty!

Note: Dispose the used battery pack in accordance of your local regulations.

1. Hold the pipettor in a horizontal position with the display facing up.

2. Press the two charging contacts simultaneously to release the battery pack. (Fig. 10.)

3. Place the new battery pack into the battery compartment and close the battery cover by pressing it lightly.

Fig. 10.

10.4. Storage

When not in use it is recommended that the pipettor is always stored in the

LINE Charging Stand or Carousel. However, during long storage periods (several months) it is recommended to disconnect the Charging Stand and Carousel from the mains outlet.

It is also advisable to remove the battery pack from the pipettor. This protects the batteries against discharging during the long storage period.

11. Performance Testing

It is recommended to check the performance of your Biohit

LINE pipettors regularly (e.g. every 3 months) and always after in-house maintenance. However, users should establish a regular testing routine for their pipettors having regard to the accuracy requirements of the application, frequency of use, number of operators using the pipettor, nature of the liquid dispensed and the acceptable maximum permissible errors established by the user. (ISO 8655-1.)

Performance test should take place in a draught-free room at 15–30

C, constant to ±0.5OC and relative humidity above 50%. The pipettor, tips and the test water should have stood in the test room sufficient time (at least 2 hours) to reach equilibrium with the room conditions. Use distilled or de-ionised water (grade 3). Use an analytical balance with a readability of 0.01 mgs.(ISO 8655-6.)

Weighting:

1. Adjust the desired test volume V

2. Carefully fit the tip onto the tip cone.

3. Fill the tip with test water and expel to waste five times to reach a humidity

equilibrium in the dead air volume.

4. Replace the tip. Pre-wet the tip by filling it once with the test water and

expel to waste.

5. Aspirate the test water, immersing the tip only 2–3 mm below the surface

of the water. Keep the pipettor vertical.

6. Withdraw the pipettor vertically and touch the tip against the side wall of

the test water container.

7. Pipette the water into the weighing vessel, touching the tip against the

inside wall of the vessel just above the liquid surface at an angle of 30

to 45O. Withdraw the pipettor by drawing the tip 8–10 mm along the inner wall of the weighing vessel.

8. Read the weight in mgs (m

9. Repeat the test cycle until 10 measurements have been recorded.

10. Convert the recorded masses (m

) to volumes (Vi) by multiplying the mass with the correction factor Z (Z-values in the table below): Vi= mi*Z

Z-values (µl/mg):

Temp. (

C) Air Pressure (kPa)

95 100 101.3 105

20.0 1.0028 1.0028 1.0029 1.0029

20.5 1.0029 1.0029 1.0030 1.0030

21.0 1.0030 1.0031 1.0031 1.0031

21.5 1.0031 1.0032 1.0032 1.0032

22.0 1.0032 1.0033 1.0033 1.0033

22.5 1.0033 1.0034 1.0034 1.0034

23.0 1.0034 1.0035 1.0035 1.0036

23.5 1.0036 1.0036 1.0036 1.0037

Note: This method is based on ISO 8655.

14. Compare the systematic error (inaccuracy) and random error (imprecision) to the performance specification values in chapter 14., or to the specifications of your own laboratory.

Note: Systematic error is the difference between the dispensed volume and the selected test volume. Random error is the scatter of the dispensed volumes around the mean of the dispensed volume. (ISO 8655-1.)

Note: Biohit specifications are achieved in strictly controlled conditions (ISO 8655-6). Users should establish acceptable maximum permissible errors based on the field of use and the accuracy requirements placed on the pipettor (ISO 8655-1).

13. For conformity evaluation calculate the random error of the measurement: Σ(V

–V)

n = number of measurement (10)

as standard deviation s =

n –1

or as coefficient of variation CV = 100s/V

11. Calculate the mean volume (V) delivered: V = (ΣV

)/10

12. For conformity evaluation calculate the systematic error e

of the

measurement: in µl: e

= V –V

Vs= selected test volume

or in %: e

= 100 (V –Vs)/V

11.1 Recalibration

The Biohit

LINE electronic pipettor’s calibration has been factory checked and certified at 22OC using grade 3 distilled water according to ISO 8655. The pipettor’s specifications are guaranteed only with genuine Biohit tips.

Note: Biohit offers an accredited calibration service. Please contact your local Biohit representative for further information.

The length of the piston stroke is electronically monitored and the pipettor does not normally need recalibration. However, for special applications the Biohit

LINE pipettors can be recalibrated in PIPET modes (excluding P MANUAL) for

one selected volume at a time as follows:

1. Press to display PIPET
