Dolomite presents new range of Piezoelectric Pumps

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 flexibility.

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.
