Masterflex L/S compact, low-flow, variable-speed drive, 115/230 VAC

SI-77200-20
$516.00 USD/EACH

  • Stackable, compact pump drive delivers versatile performance in limited space

  • Flow rate: 2.1 to 560 mL/min; flow rate depends on drive rpm and tubing size.

  • Stackable, compact drive measures 5-3/8"L x 5-3/16"W x 4-1/2"H —perfect for small work areas.

  • Painted steel housing is IP22 rated. Housing protects drive from vertically falling water.

  • Separate single-turn speed control and on/off switch with green power indicator; maintain speed setting while turning pump on/off.

  • MAX button runs pump at maximum rpm—use to prime or to rapidly flush tubing.

  • Reversible permanent magnet DC motor lets you pump in either direction.

  • Remote control options on the back of pump. Start/stop pump via contact closure.

  • Drive accepts two different pump head types: Standard and Easy-Load®.

Compact drives are a perfect upgrade from a Masterflex® C/L® tubing pump. Ideal for when you need to pump fluid at a higher rate, but space is limited in your lab.
Use these drives with L/S® precision pump tubing in sizes L/S® 13, L/S® 14, L/S® 16, L/S® 25, L/S® 17. Only silicone and C-FLEX® tubing formulations are recommended for L/S® 17 and L/S® 25 size tubing.
