Dolomite has introduced a range of piezoelectric pumps designed for accurately handling small volumes of fluid within microfluidic systems.
The piezoelectric pumps are small in size and are lightweight.
They are suitable for easy integration into experimental setups and can be used in portable microfluidic devices.
Their 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 0.8, 1.6 or 2.4mm.
The piezoelectric pumps provide a flexible, low-power pump solution that fits into tight spaces.
They are said to enhance instrument development and benefit a range of industries, including consumer electronics, medical instruments, fuel cells and microfluidic experiments.
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 set up the micropumps within their fluidic systems.
