The core elements of this pump unit are the miniature piezo pump SDMP302 and a miniature needle valve, which allows to regulate the flow from a few µl/min to approx. 1.5 ml/min. These components reduce the usual pulsation significantly.
Since this pump unit can be used with AAA or R03 batteries, it is suitable for circulating cell culture medium in a thermostatic chamber or for pumping liquids in microfluidic chips under the microscope, for example. Its dimensions are very compact at 70 x 25 x 94 mm.
