Masterflex L/S Reduced-Pulsation Cartridge pump head

The Reduced-Pulsation Cartridge pump head offers synchronous multichannel pumping over a wide range of flow rates.

  • Precision molded housing
  • Fast tubing changes: cartridge snap in and out easily
  • 6 or 8 rollers for reduced pulsation and lower flow rates
  • 1 up to 12 cartridges: 6-roller version accepts 2 or 6 large cartridges, 8-roller version accepts 4 or 12 small cartridges
  • From 0.00005 to 350 mL/min and up to 600 rpm depending on the pump drive
  • Adjustable occlusion optimized for each tubing size
  • Compatible with 2-stop microbore or Masterflex L/S tubing

Tip: to further reduce the pulsation, cartridges can be mounted in opposite directions to balance their offset occlusion. Just connect the two tubes with a Y-connector to get the resulting flow.

Setup for reduced pulsation using Cartridge pump head

Cartridge

Manufactured in polycarbonate and glass-filled nylon, the cartridges do not need any tool to be loaded on the pump head. Their occlusion “wedge” design provides accurate and more balanced flow control.

The 6-roller pump head supports 2 or 6 large cartridges, while the 8-roller pump head supports 4 or 12 small cartridges.

Compatibility:

  • Small cartridge: all 2-stop microbore
  • Large cartridge: Masterflex L/S 14, 16, 25, 17

See tubing recommendations in the "Specifications" tab.

Cartridges must be purchased separately.
