The new Cole-Parmer Modular Touch-Screen Dispensing Pump offers an abundance of features in an easy-to-programme interface. Users can quickly set up single- or multiple-step programmes on the touch screen. The controller stores up to 50 programmes with up to 20 steps each, with easy recall for later use. Programmes can be stored on a PC for retrieval and validation of experimental protocols.
Users can choose constant flow rate, stepped flow, ramped flow, or pulsed flow. Pump or dispense by volume or time; flow range is 0.001 to 1500mL/min with Masterflex L/S pump tubing. Advanced options include programme linkage, step repeat, go-to step statements and programme alarms. Screen lockout prevents inadvertent programme changes. Forward and reverse prime functions rapidly fill or purge tubing.
The pump includes the Masterflex Easy-Load II pump head with automatic tubing retention, which makes tubing changes quick and easy. The pump controller is preprogrammed with maximum and minimum flow rates for all accepted tubing sizes. Tubing calibration function ensures flow accuracy and allows the user to select calibration volume based on the volume being dispensed.
