This pump head features 3 convex rollers revolving in a concave tube bed which allows cells or particles to escape through a gap towards tubing wall to minimize damage. It is ideal for inoculating or harvesting mammalian cells.
Adjustable Pump Rollers
On this pump-head, the 3 convex rollers can be adjusted and pressed symmetrically against the concave tube-bed, enabling the use of pump tubing with various wall thicknesses.
Please note: The listed flow-rates are approximate values in ml/min. They have been determined under the following conditions:
The exact flow-rate depends on a number of parameters including quality and age of the tubing, pressure onto the tube-bed (adjustable), back-pressure, viscosity of fluid, temperature, etc.
Adjustable roller pressure accomodates wide range of tubing durometers (stiffness).
Very simple tube-loading
This pump-head accepts tubing with different diameters and wall thicknesses with ease. Thanks to the adjustable pump rollers, this is an ideal pump-head for media with high viscosity, or with a certain level of solid content.
