3. The peristaltic tube
The supplied peristaltic tube is made
from Silicone. Please make sure the
reagents you intend to use are
compatible with these material.
3. A. Clamping the peristaltic tube
The pump controller is delivered with a
IDØ2.0mm Silicone tube.
Move the lever up to open the clamp and
remove the clamp from the pump.
Insert the tube into the two tube holders
on each side of the tube clamp and
make sure the tube follows tangent and
the arc of the clamp.
Push the tube clamp back onto the pump
and lower the lever—the tube is now
occluded by the rollers.
3.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 tube deformation and ensure that
accuracy/precision is maximised.
Release the pressure by lifting the
pressure lever
3.C. Replacing the tube
Tube need replacing when worn out or
wherever you intend to change the
dispense volume range in which you
work—for smaller or larger dispense
volumes.
Lift the pressure lever and replace the
tube, making sure that you have installed
the tube centrally and that the tube is
fully engaged by the tube guides.

4. The choice of tubing
The unit can work either with fixed length tubing—75mm long within the tube clamp, or with
continuous tubing which in effect does not have any length restriction. In both cases, the
Clamp
correct tube clips have to be installed in the clamp.
For the continuous tubing there are three sizes of tube clips:.
1.
Marked '1' for ID1.0mm tube
2.
Marked '2' for ID 2.0mm tube
3.
Marked '3' for ID 3.0mm tube
Clip No. 2 is used for the fixed length tubing.
