Time-Pressure Dosing

For more precision

Your benefit

  • Expert advice thanks to many years of experience in microfluidic dosing
  • Broad selection of suitable components of the highest quality
  • Precise regulation with high switching frequency
  • Components with long life cycle and excellent cleanability
  • Flexible dosing processes, adapted to your application

To achieve reliable measurement results in a laboratory environment, the exact dosing of samples, reagents and cleaning agents is essential. This is why time-pressure dosing can be ideal for you, as it enables individually and precisely adjustable dosing volumes over a defined period. Bürkert micro-valves are designed to maintain dosing speeds and precision and can guarantee a high level of reproducibility and repeatability. The dosing volume is individually adjustable and provides the user with greater flexibility in the dosing process.

Way of proceeding

In-time-pressure dosing the medium is stored in a pressurized tank and is carried through a valve to the dosing needle. Parameters such as tank pressure, flow resistance, product viscosity and temperature of the medium are carefully controlled. The valve controls the flow of the medium by either opening or closing the stream of flow for a defined amount of time per switching cycle. Since the medium is driven by air pressure instead of a pumping mechanism, the process does not contain any mechanical moving parts in the stream of the medium.

Time-Pressure Dosing
Time-Pressure Dosing

       

A coil always heats up during operation. To protect the medium from this heat, Bürkert valves are media separated, which means the coil and fluid chamber are separated by a diaphragm, which isolates the medium. In addition, the valves are available with integrated power reduction to reduce the heat output of the coil even more.
