The Precision Pressure Control System P2CS is designed for precise and artefact-free fluid flow in μ-channels and capillaries. The goal is to provide precise control over flow rates and pressures to increase the quality of measurements.
It achieves fastest and best possible control only limited by physical laws. Gentle and ultra constant flow rates (low pressure) do preserve fragile polymer of biological structures in flow, fast flow rates (high pressure) are used to rapidly exchange fluids and remove dust and air bubbles. Continuous transition from negative to positive pressures allow e. g. oscillatory flow.
The P2CS is a simple and compact system consisting of two main components: the pressure source (optional) and the pressure controller (P2CS).

Advantages of the system 

Compact and rugged design. Simple to use.
No contact with fluids, no contamination, no cleaning is required. All liquids reside externally on-chip
Pressure range covers negative and positive pressures from ±1 mbar up to 2 bars. A high pressure and low pressure sensor provide high precision and robustness
Resolution down to 1 μbar which corresponds to a water column of 10 μm
Open control interface protocol allows control with LabVIEW, Matlab, VisualBasic and many others (RS232, TCP/IP, USB2, Bluetooth), source code is provided
Optimum of precision and speed

Some Applications 

Dynamic perfusion during experiment (e.g. in electrophysiology)
Stimulation of immune responses or signalling pathways or shear flow
Pressure driven actuation of membranes and molecules
Shear flow assays (cardiomyocytes)
Polymer and nanotube orientation
