2 Goals and purpose

The Department of Biochemistry and Biophysics wishes to purchase a peristaltic pump to drive a perfusion system on an electrophysiology setup.

3 Requirement specification

The peristaltic pump will be used to deliver and remove solutions from a slice chamber under a microscope during electrophysiological recordings. For this reason, the pump should be equipped with at least 10 rollers, to ensure minimal flow pulsatility, and have two channels. It must be possible to control the flow rate of the pump between (at least) 0.001 and 30 ml/min, and it should accept tubing with an inner diameter range of 0.5 to 3.0 mm. The pump should have a digital control interface, and the unit should be compact with dimensions ideally no greater than 25 x 25 x 25 cm

The desired delivery time is within two months of order placement. The estimated delivery timeframe should be stated in the quotation.
