Masterflex L/S standard digital drive with remote capabilities, 10-600 rpm. Cole-Parmer Masterflex L/S Brushless Digital Standard Drive 7523-40 is designed to automate laboratory, process applications or as a stand-alone dispensing pump. With a flow rate of 0.6 to 3400 mL/min, the Brushless Computer Drive flow rate depends on drive rpm and tubing size. Achieve lower flow rates with cartridge or multichannel heads and microbore tubing.

The Cole-Parmer Masterflex L/S Easy-Load 3 Pump Head for Precision Tubing, SS Rotor Model 77800-60 features an automatic retention mechanism that makes loading and unloading tubing easier than ever. The spring-loaded occlusion lever opens the occlusion bed and simultaneously retracts the tubing retainers so that tubing slips right in. Close the lever and start the pump—the retainers automatically grip and hold the tubing securely in place. The occlusion bed applies optimal occlusion force and the wide occlusion angle prevents fluid backflow up to the rated pressure of the tubing.

Features: 

• Mount and stack heads without tools or hardware; automatic tubing retention speeds setup and changeover
• Flow range: 0.06 to 2300 mL/min depending on drive rpm and tubing size
• Each pump head for precision pump tubing accepts all six precision tubing sizes—L/S® 13, L/S® 14, L/S®16, L/S® 25, L/S® 17, and L/S® 18
• Twist-lock mounting feature lets you mount and stack heads in seconds.
• Included mounting plate adapts Easy-Load® 3 to L/S drives—locking tab secures pump head during operation in either direction
• Polypropylene (PP) housing with CRS or SS rotor—CRS rotor is more economical while SS offers greater durability and chemical resistance.
• Stack up to four heads to increase flow capacity and for multiple-channel applications; see individual drive specifications for maximum number of heads to be mounted.
