Dolomite’s new Stainless Steel Piezoelectric Pump with Tube Barbs (Part No. 3200312)

Royston, UK – Dolomite, a world leader in microfluidic design and manufacture, has launched a new range of self-priming Stainless Steel Piezoelectric Pumps providing a flexible solution for handling of small volumes of fluid within microfluidic systems. Available with and without tube barbs the low power miniature pumps (~7.5mW) benefit a wide range of industries and applications including consumer electronics, medical instruments, fuel cells and microfluidic experimentations.

Fabricated from layers of bonded stainless steel foils, the Piezoelectric Pumps offer excellent chemical compatibility and are particularly suited to being supplied in high volume providing a very cost-effective solution for disposable devices. Extremely small in size and lightweight (<1g), they="" are="" also="" ideal="" for="" easy="" integration="" into="" experimental="" set-ups="" and="" can="" be="" used="" in="" portable="" microfluidic="" devices.="" together="" with="" dolomite’s="" stainless="" steel="" piezoelectric="" pump="" control="" board="" (part="" no.="" 3200313)="" the="" compact="" microfluidic="" pumps="" can="" be="" controlled="" and="" powered="" through="" a="" usb="" input="" facilitating="" instrument="" development="" as="" well="" as="" offering="" increased="" user="">

Their unique technology uses the piezoelectric effect which converts electrical energy into mechanical energy for the actuation of a stainless steel diaphragm, resulting in fluid movement through the diaphragm chamber. By varying the applied voltage and frequency, users can easily adjust the flow rate from 20µl/min to 2800µl/min and pressure from -10kPa to 90kPa.
