The Benchtop PP2000 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 – 9 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.
