<strong>Osmotex</strong> M8000 <strong>micropump</strong>s operate bubble<strong>free</strong><br />
thanks to a reversible <strong>electro</strong>de reaction<br />
combined with low-frequency flow reversal. The<br />
rectifying unit assures that a continuous, uni-<br />
directional flow is delivered to your application.<br />
Features & advantages<br />
• Flow rates up to 50 µl/min<br />
• Pressures 0.1 to 3 PSI<br />
• Operates without <strong>electro</strong>lysis and bubble formation<br />
• Compact sealed package<br />
• Power consumption in low mW range<br />
Target market<br />
The target market for the <strong>micropump</strong> system is manufacturers<br />
and developers of microfluidic technology such as labon-chip<br />
and micro fuel cells. <strong>Osmotex</strong> offers system components,<br />
standard or tailored, for integration in disposable and<br />
non-disposable OEM products.<br />
Evaluation kits<br />
<strong>Osmotex</strong> offers complete evaluation kits including<br />
the following components:<br />
• <strong>Osmotex</strong> <strong>micropump</strong> with <strong>electro</strong>des<br />
(diameter 16 mm, thickness 2 mm)<br />
• Pump enclosure with standard electrical<br />
and fluidic connectors<br />
• Active valve-based flow rectifier<br />
• Electronic control unit for pumps and<br />
rectifier (programmable, with USB interface)<br />
All products can also be purchased separately.<br />
Flow characteristics<br />
For alcohols, the smooth flow is interrupted by a small flow<br />
spike from the rectifier at each internal flow reversal, typically<br />
every hour. For aqueous solutions the flow is decreasing in<br />
each pulse until the internal flow reversal, typically every 20<br />
seconds. Flow patterns for both class of fluids are shown to<br />
the right. In both cases, the pumping is <strong>free</strong> of <strong>electro</strong>lysis<br />
and bubble formation.<br />

High precision flow<br />
The pumps can be delivered with a flow sensor, which together<br />
with the pump control unit guarantees a precise flow<br />
rate independent of the work load (counter pressure and<br />
flow resistance in the system, or other variable conditions).<br />
Typical performance of pumping system:<br />
Alcohols / fuel cell applications:<br />
• Voltage: up to 15 V<br />
• Flow rates 1 to 40 µl/min<br />
• Pressures up to 3 PSI (at zero flow)<br />
• AC operation: up to 5 hours pulse length<br />
• Power consumption: 2 to 10 mW<br />
Water / aqueous:<br />
• Voltage: from 0.5 V up to 2 V<br />
• Flow rates up to 20 µl/min<br />
• Pressures up to 0.2 PSI<br />
• AC operation: 10 to 120 seconds pulse length<br />
• Power consumption: 0.5 to 2 mW<br />
