The only part of a peristaltic pump that comes in contact with the liquid is the tubing. This maintains the sterility of fluid and the pump.
More than 20 tubing formulations and sizes are available for peristaltic pumps for excellent compatibility with a variety of liquids.
Self priming - peristaltic pumps can draw fluid into the tubing when starting dry, up to 8.8 m suction lift. Other pumps require user to fill pump and suction line with fluid before use which can be inconvenient and also create potential for hazardous spills or contamination.
Gentle pumping action - low shear - makes a peristaltic pump ideal for handling cells and large proteins, as the pumping action will not damage the content.
Variable speed options available on some peristaltic pumps, making those ideal for dosing applications.
The fluid does not contact the peristaltic pump so there are no parts to clean such as valves, diaphragms, seals etc. All you have to do is clean or replace the tubing. This easy tubing replacement means reduced maintenance times.
A peristaltic pump is non-siphoning which means that they prevent back flow into the system. This promotes accuracy during dispensing.
