**P ^{2}CS – Think Positive, Think Pressure Control System!**

Do you want to push and pull the liquid on a chip or in a capillary gently? Do you want to stop the flow at the place where you can observe it in an optimal way? Do you want to be independent of the volume control at the microscopic scale? Then try the pressure-driven approach in microfluidics.

P^{2}CS is designed for **controlling pressure** and, thus, the **fluid ****flow in microfluidic experiments and microsystems**. Standard version of the pressure control system achieves flow stabilization (100 mbar step) after 17 ms and is free of overshootings.

**P ^{2}CS Plus – New Thinking – New Pressure Control System!**

In our novel version of the microfluidic pressure control system with two pressure levels we extended the flow-rate range in order to cover **six**** orders of magnitude**, which is unique on the market.

Further, the new pressure control system P^{2}CS Plus provides higher slew-rate, which allows for faster reaction on the expense of a higher gas consumption (settle time: typ. 6 ms (100mbar step, ∆p =1’400mbar); slew rate: up to 15.5 mbar/ms (∆p = 1’400mbar))

## Applications of the Pressure Control System P^{2}CS

## Advantages of the pressure control system P^{2}CS

P

^{2}CS Plus achieves 100 mbar steps in 7 ms.

^{2}CS Plus is controlled with plain-text commands which allows to integrate it in almost all software solutions as LabVIEW, MatLab, scilab, own developments.

^{2}CS is real time (e.g. pulses have exactly the same length).
