More About this Item

Mount the reusable adapter to your Masterflex L/S drive and the pump head simply snaps into place. Standard luer connectors enable quick and secure connections to inlet and outlet tubing.

Rotary, volumetric pistons produce steady, pulseless flow with high volume and flow rate accuracy. The consistent rate of flow over time from the dual pumping chambers minimizes the need for calibration.

Flow rate accuracy will be better than 3%. Volume accuracy will be 3% or better at volumes below 2.5 mL; 1% or better at volumes greater than 2.5 mL.

Note: maximum recommended speed is 100 rpm for optimal life and performance.

      A:

      This head has a lifetime of 18 hours at 250 mL/min and 1.5 bar. We do not have chemical compatibility data on 75% phosphoric acid.
