Reduced Pulsation L/S® Multichannel Cartridge Pump Heads
Get low-pulsation flow from up to 12 channels
Features
· Improved retainer design holds tubing securely in place
These pump heads are available with six or eight rollers. The greater the number of rollers, the lower the pulsation. They feature stainless steel rotors, Rulon® rollers, and PSF ends. Occlusion is offset, tangential, and adjustable. For large cartridges, set tubing retainers to your tube size and you are ready to pump. On small cartridges, optimum retention is preset—simply load tubing and start pumping.
