Dolomite has introduced a connector for easy and direct integration of Dolomite microfluidic chips with Nano Fusion Technology (NFT) micro-electro-osmotic pumps.
This two-channel miniature pumping connector provides a low internal volume of 8ul and a flow rate range of 0.1ul/min to 6ul/min.
Providing a smooth flow and precise control in the low flow rate range, the micro-electro-osmotic pump connector enables the development of complete small-scale pumping systems ideal for use in a range of applications, for example, academic, handheld instrumentation, drug discovery, clinical diagnostics and so on.
With no moving parts or pulsation, a smooth flow is obtained at high pressures up to 2,000kPa.
Powered via connection to a DC supply or battery, electro-osmotic flow is generated in the pump through the application of a low voltage across the two electrodes.
For more advanced management of flow rates, a pulse-width-modulated (PWM) power source and micro flowmeter can be supplied for closed-loop flow-rate control.
The pump can operate directly with either de-ionised water or methanol, however using indirect methods such as using a sample loop between the pump and the on-chip working area, the micro electro-osmotic pump can be used with any liquid.
