• Unique convex rollers cause minimal cell lysis


• Ideal for mammalian cell inoculating, harvesting, or cell suspension transfers


• Elevated differential pressures (Pro-281 and Pro-381)


• Suitable for viscous fluids and fluids containing a high content of sensitive solids


• Applications requiring hygienic conditions, durability and reliability


• Installs rapidly


• Easily interchanged with other MCP/BVP pump heads


Pro-280


• Coated aluminum pump-head


• Can be dismantled for cleaning


• Stainless steel rollers


• Self-centering tube-track, allows tube to lie in the optimum position, which considerably lengthens the tube-life


• For applications which require hygienic conditions, reliability and durability


• Ideal for use in chemical, biotechnological and pharmaceutical processes and in food industry


Pro-281


• Same as Pro-280 but


• For tubing with 2.4 mm wall thickness


• Especially recommended for:


– Elevated differential pressures


– Viscous fluids


Pro-380


• Same as Pro-280 but


• Less pulsation thanks to 3 rollers


• Slightly lower flow rate


Pro-381


• Same as Pro-380 but


• For tubing with 2.4 mm wall thickness


• Especially recommended for:


– Elevated differential pressures


– Viscous fluids
These pumps heads provide gentle pumping action and are suitable for many applications, including cell suspensions.


The model Pro-280 pump head is gentle enough to use for highly viscous liquids with concentrated viable cells. Comparisons to gear, piston and centrifugal pumps proved that peristaltic pumps are the only suitable and sterilizable pump system for gently pumping media containing living cells.
