Positive Displacement Pump
Displaces Volumes from 1 µL
The PUMP-IT-1000 Positive Displacement Pump is a pulsed pump that displaces from 1 µL to 250 µL of fluid with each pump or cycle. The amount of fluid displaced with each cycle is set via software. The amount pumped is precise to 0.3% with
repeatability of better than 0.5%. The PUMP-IT-1000 is $999.
Applications
The PUMP-IT is particularly useful for those wanting to automate the delivery of
reagents into accurate flow setups. Typical applications include blood chemistry, blood analysis, particle sizing, in vitro diagnostics and biopharmaceutical analysis.
PC/Software-controlled
The pump connects to a PC via an RS-232 port and a controller box and is controlled with software (included). The PUMP-IT is a low-cost alternative to expensive syringe, vacuum, peristaltic and other pumps. Not only can you select the displacement amount, you can regulate the speed of the displacement via software.
Long-life Design
For accurate mixing and/or dilution of fluids, the pump has upper and lower limits that can be set mechanically and via the software. The pump provides a ripple-free and bubble-free flow. The pump’s piston and head are made out of PEEK, while the body is made from aluminum. The piston in the pump will last about 1-2 million cycles before it shows evidence of wear. The PUMP-IT has the flexibility to be positioned in any orientation.
What’s Included
The PUMP-IT-1000 comes with the controller box and power supply; an RS-232 cord; software; 10 feet of tubing; various nylon fittings, plugs and caps; and a
250-µL sample bottle.
