Cole-Parmer has introduced the Masterflex L/S peristaltic pump system (WZ-77921-70).
Featuring a precision digital drive with a maintenance-free high-accuracy motor and a graphical user interface, this digital peristaltic pump system can solve most dispensing and filling applications in the laboratory.
Masterflex peristaltic pumps offer quick setup and precise operation for metering, transfer and dispensing applications within a laboratory or process area.
The precision pump offers a brushless motor with +/-0.1 per cent accuracy, precise speed control (+/-0.1 per cent), menu-driven interface with options of seven languages and analogue remote control capabilities.
These features make this pump suitable for both stand-alone laboratory work and automated process applications.
Pump performance can be viewed continuously on the graphical user interface.
The user can select from four operating modes: continuous/transfer run and three dispense modes, including batch dispensing and dispensing by volume with an optional time delay of one to 9,999 seconds between each dispense cycle for automated dispensing.
To achieve dispense volumes with repeated accuracies up to +/-0.25 per cent, users can follow the calibration procedure.
The pump can save one calibration per tubing size and retains the calibration even when the power is turned off.
When using a peristaltic pump the media is confined within the tubing, thereby eliminating cross contamination between the media and the pump.
Combined low maintenance and gentle pumping action with low shear on the media makes peristaltic pumps suitable for applications requiring high purity, metering of chemicals, pharmaceutical products, food additives and food product.
This laboratory pump package includes a Masterflex digital drive, an Easy-Load II pump head for quick tubing changes and Masterflex L/S 24 Tygon LFL tubing.
Alternate tubing can be chosen as per the application requirements from the wide range of Masterflex tubing.
