Easily adjust speed of compact multichannel pump.

• Digital models have preprogrammed tube diameters and flow rates for easy set up
• Dispense by volume or set time intervals
• Display shows speed in 1% steps and flow rate in ml/min

• Designed with 4 channels and 12 rollers

These space-saving pumps provide up to four pumping channels while using very little benchtop space. Self-lubricating, Ertalyte® rollers provide consistent flow with reduced tubing wear. Use Click’n’go™ minicartridges for consistent results. Reverse flow direction with the flip of a switch. Select two- or four-channel pumps; twelve roller pumps provide smooth, even flow.

Continuously pump or dispense in any of four modes:
– Flow rate: 0.003 to 59 ml/min
– By time: 0.1 seconds to 999.9 hours
– Batches: set delay between dispensed volumes
– Drip-free: program back-steps to prevent drips

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, 0 to 10 VDC, 0 to 20, 4 to 20 mA for speed control, start/stop, reverse direction, and autostart via contact closure (DB15 male); footswitch and hand dispenser (three-pin DIN port).

Choose optional minicartridges with adjustable occlusion to manually vary pressure on each channel. Pumps are designed to be used with 3-stop tubing. (Scroll down to see all accessory choices.)
