Dolomite Launches New Piezoelectric Pumps for Accurate Liquid Handling in Microfluidic Systems
01 Jun 2011

Dolomite, a world leader in microfluidic design and manufacture, has launched a new range of Piezoelectric Pumps providing a flexible solution for handling small volumes of fluid within microfluidic systems.

Extremely small in size, the lightweight Piezoelectric Pumps are ideal for easy integration into experimental set-ups and can be used in portable microfluidic devices. Their unique technology uses the piezoelectric effect which converts electrical energy into mechanical energy for the actuation of a diaphragm, resulting in fluid movement through the diaphragm chamber. By varying the applied voltage and frequency, the flow rate can be adjusted from 3ml/min to a maximum of 20ml/min enabling experimental parameters to be optimised.
The pump features two fluid ports which can be connected to soft tubing with an internal diameter of 0.8mm, 1.6mm or 2.4mm. Providing a flexible low power pump solution which fits into tight spaces, the Piezoelectric Pumps enhance instrument development and benefit a wide range of industries including consumer electronics, medical instruments, fuel cells and microfluidic experimentations.

Dolomite also provides a compact Piezoelectric Pump Controller for the flexible control of up to two pumps for applications such as point of care diagnostics where a sample and reagent are mixed together in a microfluidic system. The Controller features a memory function to store the latest setting used enabling users to quickly setup the micropumps within their fluidic systems.
