The peristaltic tube
The peristaltic tube is made from
Santoprene and the connectors are
Nylon (PA). Please make sure the
reagents you intend to use are
compatible with these materials
(See Chart).
1. A. Clamping the peristaltic tube
The pump controller is delivered with
a IDØ2mm Santoprene tube. In
order to reduce deformation caused
by clamping the pressure lever
(1)
is
supplied in the open position .
Before use ensure you turn the lever
down to the fully clamped position
1.B. Releasing the peristaltic tube
when you have finished
Whenever the pump is not in use for
long periods of time it is important to
release the pressure off the tube.
This will reduce the possibility of the
tube’s permanent deformation and
ensure that accuracy/precision is
maximised.
Release the pressure by lifting the
pressure lever
1.C. Replacing the tube
For work in small volumes use the
IDØ1.0mm tube which is available
as an accessory.
Lift the lever and remove the pump’s
cover. Pull out both tube holders
and remove from the cover. Replace
with a new tube.

The pressure lever moves the pump cover towards the
rollers and thus clamps the tube between the cover and
the rollers.

10Xsec you wish to have between the dispenses— from 1
second to 99 seconds.

Press ‘INTERVALS’ and the second set of digits will flash. This
digits denote the number of dispenses you wish to have—from 1
to 98 dispenses.
5.
Using the ‘UP’ & ‘DOWN’ keys enter the number of dispense
events—between 1 and 98.
6.

colon between the two sets of digits flashes to indicate that an
interval dispense mode has been entered into the unit. You can
now adjust the volume as indicated in the previous paragraph.
7.
Press ‘START’ and the controller will dispense the set volume in
the interval mode which you have entered into the unit.
