3 Operation
3.1 Setting the volume (only Research plus variable)
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.
 Turn the volume setting ring as depicted to adjust the
volume.
The height of the control button changes as the volume is
adjusted.
The numbers on the volume display are to be read from
the top to the bottom. The decimal places are below the
hyphen.
The volume is displayed up to 1 000 μL in μL. For the 5 mL
and 10 mL sizes, the volume is displayed in mL.
We recommend to adjust the volume setting from a higher
value to a lower value. If required, turn beyond the
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).
