The rotating pipette stand makes for an organized workplace. The new kind of attachment means that the pipette is no longer held at the bottom, ruling out potential contamination of a pipette by it being put on a stand.
All the older models of pipette can likewise be stored in the new pipette carousel.
In addition to the pipette carousel, there is a practical pipette holder for attachment to the wall. This means the pipette is always within reach and does not waste any valuable working space.
Dispensing is a routine, manual task for medical, molecular biology and pharmaceutical applications. This manual offers an overview of the current dispensing techniques and the main application fields in scientific and industrial laboratories. Todayâ€™s laboratories require extremely precise pipetting/dispensing processes down to the microliter range, and there are many products available for the transport and preparation of liquid samples.
Now in its third edition, this manual addresses the physical fundamentals and utilization limits of the current techniques. Quality management in terms of international standards is also covered.

What are the main features of the Eppendorf Research plus?
Main features are: very low weight, spring loaded tip cone (exception: 5 mL and 10 mL Research plus) which leads to an easy and homogeneous tip attachment even when working with a multi-channel pipette and thus, to very low operation forces and finally, an easy adjustment by the user. In addition, the Research plus shows a very good accuracy and precision, is fully autoclavable at 121 Â°C, 1 bar for 20 min, features excellent chemical resistance and has an adjustment display offering optical control if an adjustment of the pipette has been performed.
In which sizes is the Eppendorf Research plus available?
The Research plus is available as fixed-volume pipettes, adjustable pipettes and as 8-channel and 12-channel pipettes (with adjustable volumes).
Besides the present volume range of our Research Pipettes, the Research plus is offered in the following additional sizes:
Fixed-volume pipettes: 10 ÂµL pipette for pipette tips 0.1-20 ÂµL, 20 ÂµL pipette for pipette tips 0.5-20 ÂµL L and 200 ÂµL pipette for pipette tips 2-200 ÂµL.
Adjustable pipettes: 2-20 ÂµL pipette for pipette tips 0.5-20 ÂµL L, 30-300 ÂµL pipette for pipette tips 20-300 ÂµL.
These new models feature an even higher precision due to a smaller air-cushion in the pipette tip compared to tips with higher volumes.
For detailed information on the different model sizes, please check the ordering information Research plus
Is the Research plus resistent to concentrated acids?
Yes. Please notice that the usage of aggressive chemicals over a longer period of time will reduce the life span of the pipette.
Is a gravimetric test necessary after resetting the adjustment display to "0"?
From a technical standpoint, no. Only for certified laboratories, a gravimetric test might be necessary for documentation purposes.
Is accuracy (systematic error) affected if the Research plus multi-channel pipette is not fully attached with tips or if individual channels of the pipette are removed?
It does not affect the accuracy of pipetting if the Research plus multi-channel pipette is not fully attached with tips or if individual channels are removed.
Is the Research plus compatible with hydrofluoric acid?
Yes. Please notice that the usage of aggressive chemicals like hydrofluoric acid over a longer period of time will reduce the life span of the pipette.
Is the Research plus compatible with hydrochloric acid?
Yes. Please notice that the usage of aggressive chemicals like hydrochloric acid over a longer period of time will reduce the life span of the pipette.
How many overnight cycles or total hours of UV irradiation can the Research plus withstand before any discoloration or change of the material will be visible?
We tested UV radiation over a time period of 165 hours of continuos radiation and under very intense conditions. There were no visible discoloration or changes in the material.
Is it necessary to re-grease the piston of the pipette after autoclaving?
No, it is not necessary.
Can the Research plus be autoclaved if the locking ring is installed to deactivate the spring loading?
Yes. The locking ring is made of PPS (polyphenylene sulfide) and therefore autoclavable (121 Â°C, 1 bar, 20 min).
Is the Research plus compatible with sodium hydroxide (>10 %)?
Is the Research plus compatible with 65 % nitric acid?
Yes. Please notice that the usage of aggressive chemicals like nitric acid over a longer period of time will reduce the life span of the pipette.
When do I have to lubricate the piston of a Research plus pipette?
If the pipette is contaminated with a liquid which enters the pipette's internal parts, the user will have to disassemble the lower part, clean the piston and the nose cone . In this case, the grease is removed from the piston and the piston needs to be regreased before reassembly. To do so, we recommend to use our pipette grease (1 g, order no. 0013 063.010).
Do I need to disassemble the Research plus before autoclaving?
No. It can be autoclaved in one piece (121 Â°C, 1 bar, 20 min).
What are the settings of the Research plus pipette for liquids of different viscosities or specific densities?
The user manual of the Research plus mentions specific settings for some volumes of the most common liquid classes. These values are for orientation only as the systematic and random error are affected by the mode of operation, the tip used and other factors like the temperature. It is essential to check these data according to your own work method.
If my Research plus deviates significantly from the limit values, how can I find out whether this is a measuring error or a problem with the pipette?
We recommend to dismantle the pipette into its individual parts (see operating instructions) and to clean these. Afterwards calibrate your pipette following the instructions given in our SOP. Values which deviate significantly from the limit value should now no longer occur. However, if there is no contamination, please contact your local Eppendorf partner for service of your pipette.
Will water vapor enter into the pipette while it is being autoclaved, causing water vapor to bead up on the inside of the numerical volume setting display?
Vapor will penetrate the inside of the pipette during autoclaving but this will not damage anything. We tested our pipettes with 175 autoclaving cycles (121 Â°C, 1 bar, 20 min). The number of respective tests chosen corresponds to an average of 5 years of use.
Can the Research plus be washed with sodium hypochlorite for disinfection?
Yes. The outside of the tip cone and ejector sleeve can be wiped with 4 % sodium hypochlorite solution. After the exposure time of the sodium hypochlorite solution has elapsed, remove thoroughly with demineralized water.
In part 3 of the operating manual of the Research plus you recommend to adjust the volume setting from a higher value to a lower value. If required, the user should turn the value beyond the required valued and than back again. What is the reason for such a recommendation?
For technical reasons, the results are generally more precise when a volume setting is carried out from a higher down to a lower value. This is valid for all manual pipettes.
Are any O-rings or any other type of rubber gaskets present on the insides of the single-channel Research plus?
There are no single O-rings or other separate parts inside. All parts are integrated into the piston. Only the lower parts of the multi-channel Research plus pipettes are equipped with O-rings.
How should contaminations on the outside of the Research plus be removed?
We recommend to wet a cloth with water or 70% isopropanol and to remove the contamination.
How should disinfection of the Research plus be performed?
Wipe off the outer surface with disinfectant, DNA/RNA decontamination agent or 70 % isopropanol. Alternatively wipe the outside of the tip cone and ejector sleeve with 4 % sodium hypochlorite solution. After the exposure time of the sodium hypochlorite solution has elapsed, remove thoroughly with demineralized water. Alternatively the Research plus may be temporarily subjected to UV light under a sterile bench.Here we recommend the use of a Hg-lamp, 254 nm, 30 W. The distance between lamp and pipette should be approx. 60 cm.
What information is available through the adjustment display of the Research plus?
As each Research plus pipette has been calibrated and adjusted before delivery, the adjustment display shows "0". As soon as the adjustment is changed by the user, the reading on the display will be changed, too. Therefore, the adjustment display provides optical control if a pipette has been adjusted to another volume.
What do I have to observe regarding maintenance and cleaning of the Research plus?
The Research plus pipettes are easy to clean. Only the lower part should be cleaned on a regular basis, in accordance with the frequency of use. The lower part of the single-channel and multi-channel Research plus pipettes can be removed easily as described in the operating manual of the Research plus or in our Application Note 198. (http://www.eppendorf.de/int/index.php?sitemap=4.1&pb=f69dc5897412b7d4&action=support&contentid=1&catalognode=67026&productpage=7)
When should the spring loading of the single-channel Research plus pipettes be deactivated?
For dispensing tasks in which a pipette tip is used over a long time or is slightly bended, it can be helpful to deactivate the spring loading of the tip cone by installing the locking ring. This can also be helpful for pipette tips which are not designed for the Eppendorf pipette cones.
