How do I determine the volume values when calibrating gravimetrically?

The measuring values of the analysis scales are multiplied by the correction factor Z (see SOP pipettes). This takes into account the density of the water at the relevant temperature and the relevant air.

What does EN ISO 8655 cover?

ISO 8655 addresses the needs of suppliers, test houses, and users and specifies the general requirements for piston-operated liquid handling devices. It is structured in seven chapters: ISO 8655-1: Terminology, general requirements, and user recommendations ISO 8655-2: Piston pipettes ISO 8655-3: Piston burettes ISO 8655-4: Dilutors ISO 8655-5: Dispensers ISO 8655-6: Gravimetric method for the determination of measurement error ISO 8655-7: Non-gravimetric methods for assessment of equipment performance (titration, photometry)

What do the terms random error and systematic error mean in a pipette calibration?

The systematic error describes the deviation of the dispensed volume from the nominal volume or from the selected volume of the piston stroke device, and is determined by establishing the mean value of (usually) 10 measurements. The random error describes the mean variation of the dispensed volumes from the mean value of the dispensed volumes, and is determined by calculating the repeat standard deviation of (usually) 10 measurements.

Why are the Z factors listed in our SOP different from factors which can be derived from density reference values (of water)?

The Z factor is included in EN ISO 8655-6 and was incorporated into our SOP. As we understand it, it was incorporated in the standard by the Physikalisch Technische Bundesanstalt in Braunschweig. The Z factor describes the density of water at a particular temperature using a 5th degree polynomial. Furthermore, the density of water is corrected by the density of air (derived from air pressure) and a fixed correction value for balances. These corrections are the key reasons for the deviation from density values in various books of tables.

How can the Multipette/Repeater M4 be calibrated?

To calibrate Multipettes/Repeaters in accordance with EN ISO 8655, three different volumes with ten measured values each have to be checked. These three volumes are the nominal volume (= the maximum volume to be dispensed), 50% of the nominal volume and 10% of the nominal volume of the Combitips advanced used. The checking procedure, the test conditions, and the limits in accordance with EN ISO 8655 are described in our "Eppendorf SOP for checking pipettes". The SOP is available on our web page.

Can the M4 Multipette/Repeater M4 be autoclaved?

No, the Multipette/Repeater M4 cannot be autoclaved. We recommend wiping the device with a cloth that has been moistened with a disinfectant (e.g. 60% isopropanol, 12% bleach). Please ensure that no moisture can get into the device during cleaning.

Can Combitips advanced advanced be partially filled as well?

Yes, with the Multipette/Repeater M4, Combitips advanced can be partially filled as well. To ensure accurate dosing, it is mandatory that the pistons of the Combitips advanced are moved to a defined position after aspiration. Discard the steps by pressing the operating lever until the display stops flashing and “steps 0” is displayed. If the selection dial position is below 4, several steps must be discarded.

Why can the Multipette/Repeater M4 only be operated with Combitips advanced?

When using a positive displacement system, the dispenser and the dispenser tip must be perfectly matched. This will ensure that the high demands with regard to precision and accuracy are reliably met. Combitips advanced are perfectly matched to Eppendorf Multipettes and, therefore, to the Multipette/Repeater M4. In combination with the center sleeve of the Multipette M4, accurate dosing for wall dispensing is supported in particular.

What is the maximum number of dispensing steps that can be carried out with the Multipette/Repeater M4?

In position 0.5, 100 dispensing steps can be performed with the Multipette/repeater M4.

What is the volume range covered by the Multipette/Repeater M4 when Combitips advanced are used?

Eppendorf offers 9 different sizes of Combitips advanced. This enables the Multipette/Repeater M4 to cover a dispensing volume of 1 µL - 10 mL.

Which chemicals can be dispensed with the Multipette/Repeater M4?

During the development of the Multipette/Repeater M4, the use of materials with a high chemical resistance was a priority. Of course, the chemical resistance of the Combitips advanced is also relevant here. You can find a detailed list of the chemical resistance for both products in the corresponding operating manual or in the instructions for use.

Can you dispense 2 µL in a free jet?

With the Combitip advanced 0.1 mL in selector dial position 1 and the Combitip advanced 0.2 mL in selector dial position 0.5, a volume of 2 µL can be dispensed in a free jet. All volumes can be dispensed in a free jet, if handled correctly. If you want to carry out all dispensing steps as a free jet, the reverse stroke should be dispensed in a free jet as well. Please note that the technical data document recommends wall dispensing.

How can I extend the life of the battery as much as possible?

The life of the battery very much depends on the type and frequency of use. To extend the life of the battery as much as possible, the Multipette M4 goes into sleep mode when it is not in use. You should also remove the Combitips advanced immediately after use and not store the Multipette M4 with the Combitip advanced inserted to extend the life of the battery.

How long will the battery last (for the use of the display) after the battery symbol appears?

If the battery symbol only shows with one segment, the battery capacity is very low. A few more dosing series can be carried out. Have a replacement battery to hand. As soon as the empty battery symbol appears, the battery should be replaced.

Does the Multipette/Repeater M4 also work without a battery?

Yes. The Multipette/Repeater M4 also works without a battery. The precision of the dosing is due to the reliable mechanics of the Multipette/Repeater M4. It will not be affected if the battery fails. To help with the selection of the correct dispensing volume, a volume table is included in the short instructions and in the operating manual. In addition, the Combitips advanced indicate the dispensing volume in selector dial position 1. This volume can be multiplied with the selector dial position to calculate the set dispensing volume.

How much does the Multipette/Repeater M4 weigh?

The Multipette/Repeater M4 only weighs 105 g.

What does the “PhysioCare concept” symbol on the Multipette/Repeater M4 mean?

The symbol means that the Multipette/Repeater M4 has been developed in accordance with the considerations of the Eppendorf PhysioCare concept. With its three areas, the concept includes the whole range of ergonomics, not just a single element. Instead of focusing on a particular product feature, the products with the PhysioCare symbol provide a holistic solution. Further details on the PhysioCare Concept ® are available at http://physiocare.eppendorf.com.

Does a specific dispensing angle need to be observed during dispensing?

Yes. If the Multipette/Repeater M4 is held at an angle that is too flat (< 45°C), dosing accuracy is affected. Hold the device as upright as possible, but in a position that is comfortable for you. Even when dispensing the last step, the Multipette/Repeater M4 should be held as straight as possible.

What does “steps” on the display mean?

The Multipette/Repeater M4 has a step counter. If a Combitip advanced is used alongside “steps” (here: dispensing steps), the number of dispensing steps that can be carried out with a full Combitip advanced is displayed. During dispensing, the number of dispensing steps that have already been carried out are displayed. When the selector dial position is adjusted, the number of dispensing steps that can still be carried out is displayed.

Can the step counter also count the dispensing steps if the Combitips advanced are only partially filled?

Yes, the step counter also counts the dispensing steps that were carried out when the Combitip advanced is only partially filled once. As with a full Combitip, the reverse stroke must be carried out first (display flashes). Please note with this type of filling that the step counter continues to count beyond the residual stroke lock.

Can the step counter also count the dispensing steps if the Combitip advanced is filled several times?

Yes, the step counter also counts the dispensing steps when the Combitip advanced is filled to capacity several times.

How are the Combitips advanced ejected?

To eject the Combitips advanced, push the lower filling lever down as far as it will go (dispensing the remaining volume). Then the Combitip advanced can be ejected without touching it, by pressing the upper operating lever.

Is it possible to attach the Multipette/Repeater M4 to a wall?

Yes. The Multipette/Repeater M4 comes with a holder which can be inserted in a pipette carousel or it can be fixed to a clean glass or ceramic surface using the enclosed adhesive strip.

How to use a Multipette M4 repetitive pipette?

The Multipette M4 is extremely easy to use: Just insert a compatible dispenser tip (Combitips advanced or ViscoTip) into the M4 while pushing the operating lever. The pipette automatically recognizes the tip size, and you can directly select the volume and steps needed for your application. The volume can even be changed between dispensing steps. Place the tip into the liquid sample and gently push the operating lever to aspirate the total volume to be dispensed. Push the operating lever once to trigger a reverse stroke needed to maximize accuracy. Afterwards, you can start dispensing into your target vessel(s) by pushing the operating lever slowly as far as it will go. Learn more in our Quick Start Guide.
