INTRODUCTION
DISTRIMAN® is a continuously adjustable repeater
pipette designed to dispense precise aliquots of
liquid safely. The DISTRIMAN can quickly transfer
volumes from 1 µL to 1.25 mL, depending on the
capacity of the DISTRITIP® (positive displacement
syringe) fitted to it. The number of aliquots that
can be dispensed depends on the volume of liquid
aspirated (up to the maximum for a given size of
syringe) and the aliquot volume selected.
This ergonomically designed product is suitable for
transferring most kinds of liquids (aqueous, volatile,
viscous, or dense) into many kinds of vials (tubes,
microplates, etc.). DISTRIMAN ensures reliable
results in any domain and in all kinds of laboratory,
for a wide variety of applications.
The positive displacement mechanism permits
precise pipetting of viscous materials (e.g.
blood, plasma, oils, etc.), including those used
in molecular biology (glycerol, enzymes, and
amplified DNA), without contaminating the pipette.
DISTRIMAN is fitted with a COLORIS™ tag,
which can identify the user or application. You
may replace the one fitted with a COLORIS of a
dierent color (as supplied, refer to Chapter 5
Maintenance on page 14).
DISTRIMAN is equipped with a direct reading
volumeter that allows precise and continuous
volume setting. The aliquots are dispensed by
pressing the push button the required number
of times (the volume between aliquots can also
be changed). A small red flag (refer to Figure 1
on page 4) indicates that the final aliquot will be
dispensed.
Because DISTRIMAN is permanently calibrated
when manufactured, there is no need for
readjustment. It is virtually maintenance free.
However, a few spare parts have been made
available in case they are damaged as the result of
extensive use.

For example, the DISTRITIP Micro is ideal for filling
a 96-well microplate. The syringe capacity is
125 µL, so the DISTRIMAN can dispense at least
96 aliquots of 1 µL.

DISTRTIPS Model
Perform the following sequence of steps in order
to operate the DISTRIMAN®.
1. Select a DISTRITIP of suitable capacity.
2. Fit the DISTRITIP to the DISTRIMAN.
3. Select the volume range on the DISTRIMAN.
4. Set the aliquot volume.
5. Lock in the selected volume.
6. Fill the DISTRITIP.
7. Dispense the aliquots.
8. Eject the DISTRITIP.
Select the DISTRITIP
Three standard DISTRITIPS are provided with
DISTRIMAN (refer to Table 1 below). Individually
wrapped sterilized versions are available.
Select the capacity* of the DISTRITIP according to
the volume and number of aliquots that you want
to dispense.
Because DISTRIMAN is continuously adjustable
you can also select any aliquot volume within the
range for the size of DISTRITIP fitted.

Fit the DISTRITIP
Take the following steps to ensure the DISTRITIP is
correctly fitted.
1. Push the filling knob downwards to its lowest
possible position, using your thumb . Hold
the filling knob firmly in place with your
thumb.
2. Hold the DISTRITIP in your other hand, place
the end of the piston into the body of the
DISTRIMAN at a right-angles to the main
axis .
3. Gently rotate the DISTRITIP downwards with
the other hand , and then snap the syringe
into place with your thumb, using moderate
pressure .
4. Finally, check that the piston of the syringe
is correctly fitted by pushing the filling knob
upwards.

NOTE
Before using DISTRIMAN, check the
selected volume range matches the
volume of the DISTRITIP.
NOTE
*Capacity refers to the maximum usable
volume of a DISTRITIP; the range refers
to the maximum and minimum aliquot
volumes that may be dispensed.
**Taking into account the systematic error,
the maximum number of aliquots varies
from 118 to 121, according to the type of
DISTRITIP used.
