2.3 Features
In combination with a Combitip, the Multipette stream/Repeater stream is a motor-driven
and electronically controlled manual dispenser which operates according to the positive
displacement principle.
2.3.1 Operating modes
The Multipette stream/Repeater stream and Multipette Xstream/Repeater Xstream have
the following operating modes:
2.3.2 Dispensing tasks and ranges
It is possible to dispense aqueous solutions, but also solutions with a higher viscosity. At a
higher viscosity, lower aspiration and dispensing speeds should be selected.
• If the lowest speed (1 bar) is used for aspiration and dispensing, it is possible to
dispense solutions with a viscosity of ≤ 300 mPa·s with ≤ 25 mL Combitips.
• If 50 mL Combitips are used, the viscosity must not exceed 100 mPa·s.
• With 0.5 mL Combitips and the highest speed setting, 5 L of water can be dispensed
in a free jet. Free jet dispensing of water is also possible with all larger Combitips. If
large volumes are dispensed in a free jet, the liquid may splash back!

Dis Dispensing gradual dispensing of liquid in equal partial volumes.
Ads Automatic
dispensing
automatic dispensing of liquid in equal partial volumes
and at fixed intervals.
Seq Sequential
dispensing
dispensing liquid in up to 16 different volumes in one
sequence.
Asp Aspirating consecutive aspiration of liquid of the same volume
into a Combitip.
Pip Pipetting aspirating and dispensing liquid.
Ttr Titration gradual dispensing of reagent into a sample solution.
Multiple aspiration of the reagent into the Combitip is
possible.
For solutions with a higher vapor pressure it is recommended to saturate the
small air bubble at the piston of the Combitip with liquid vapor by aspirating and
dispensing the liquid several times.
