These multichannel programmable pumps feature planetary gears that drive eight stainless steel rollers in unison for smooth rotation and accurate liquid flow. The four-digit LED display shows flow rate or rpm when pump is running. Use the MAX button to instantly increase speed for priming or flushing without disturbing your programmed settings.

• Planetary drive for less pulsation and longer tubing life
• Smooth rotation and accurate liquid flow provided by eight SS rotors
• Easy repeatability with four-digit LED
• Simple to use—automatic occlusion cartridges provide reproducible results
• Control via keypad, computer, or remote control

Combine tubing sizes and formulations to suit your application. Click'n'go™ cartridges feature automatic occlusion for simplified use, fewer tubing changes, and reproducible results. Adjustable occulsion cartridges are available separately. Install cartridges in one direction for low pulsation; in opposite direction for higher counter pressure.

Ideal for continuous pumping or for dispensing in any of five modes: Flow rate: 0.0004 to 44 mL/min (depending on tubing size used and model used); By time: 0.1 seconds to 999.9 hours; Batches: set delay between dispensed volumes; Drip-free: program back-steps to prevent drips; or Volume displays in ml or µl.

Pumps feature analog input and output controls, as well as an RS-232 interface for control by a computer.

Remote control capabilities: RS-232 to control all operating functions (DB9 male); 0 to 5 VDC, 0 to 10 VDC, 0 to 20 mA, 4 to 20 mA for start/stop and autostart via contact closure (DB15 male); footswitch (three-pin DIN port). Monitor speed via analog output.
