PERI ST ALTIC PUMP S Gentle Pumping Pump Heads PC4 73-3119 PC4 73-3120 These pump 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.
