Theory of Operations

The Benchtop Peristaltic Dispenser transfers low viscosity liquids by pressure
displacement applied by a turning rotor against a tube carrying the material. Usually
these pumps are chosen because the liquids are hazardous or difficult to work with
and it is advisable to limit operator contact. Another reason is that peristaltic pumps
are air free.
Dispense outputs can be timed from 0.01 - 99.99 seconds with flow speeds from
0.01-6 ml/min using PTFE tubing. The pump is bi-directional allowing suck-back after
dispense to prevent dripping of the fluid.
When dispensing UV adhesives use only black tubing. This avoids curing of the
adhesive in the tube.
The amount of product dispensed is controlled by:
– The dispensing time.
– The size of the used feedline.
– The speed of the drive.
– The size of the dispensing needle.
Various sizes of PTFE tubes, the corresponding applicator nozzles and dispensing
needles are available, see section 7.1.
