Valves
Micropumps form the tangible heart of our performance. A performance that is extended by necessary components, such as valves, to achieve full system functionality.
That is why we offer these in addition to our various micropumps. Like for example our own developed passive check valves. Additionally, we have three partners that offer you a variety of active valves:
- BMT, manufactured by Takasago from Japan.
- memetis valves by themselves or in combination with the evaluation set coming from memetis
With these valves you can switch your microfluidic system at will, as well as quickly and easily set up. Add the advantage of active monitoring and make regulation possible. Thus, you can quickly and easily make your microfluidic system intelligent and miniaturized.

The ultracompact 2/2-way media isolated bistable (BV1101) from memetis enables complex fluidic systems with very low power consumption. It is perfectly suitable for fluidics in life science and other small but complex fluidic applications. We cooperate directly with memetis GmbH.
Combined with our mp-valvedriverM it facilitates the use of the Memetis valve and enables a quick integration in e.g. embedded system or your microfluidic set-up. The mp-valvedriverM is a small, easy-to-use driver circuit designed for one bistable BV1101 or one or up to two normally-closed shape memory alloy valves as accessory for the mp6 series micropumps.

An almost silent and low power active valve from the company Takasago. We cooperate with the German representative BMT.
Combined with our mp-valvedriverT it facilitates the use of the Takasago valve and enables a quick integration in e.g. embedded systems or your microfluidic set-up. The mp-valvedriverT is a small, easy-to-use driver circuit designed for one or up to two Takasago SMV-2R-BN1F shape memory alloy valves as accessory for the mp6 series micropumps.
