a world leader in microfluidic design and manufacture, has introduced its new
Micro Electro-Osmotic Pump 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 8 µl and a flow rate range of 0.1 µl/min to 6 µl/min. Providing
an extremely 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 wide range of applications e.g. academic,
handheld instrumentation, drug discovery, clinical diagnostics etc.
With no moving parts or pulsation, a smooth flow is easily obtained at high
pressures up to 2000 kPa. 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 flow meter 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.
