The peristaltic pump is used for pumping sample and auxiliary solutions. It
can rotate in both directions.
The peristaltic pump pumps liquids based on the principle of displace-
ment. The pump tubing is clamped between the rollers (14-5) and the
tubing cartridge (14-2). During operation, the peristaltic pump drive
rotates the roller hub (14-6), so that the rollers (14-5) advance the liquid
in the pump tubing.
