Syringe Pump Dosing

For precise results

Your benefit

  • Precise dosing of low, specified fluid volumes
  • Optimal rinsability thanks to product design that virtually eliminates dead volume
  • Application-specific system

In laboratory equipment, not only the media supply but also precise dosing is extremely important to avoid false test results. This is why it is important that small volumes of fluids are measured very precisely and the risk of cross-contamination is eliminated. In order to reliably satisfy these requirements, Bürkert applies its expertise and makes use of suitable components to offer solutions for precision dosing with ultra-short reaction times. The components are produced with chemically resistant material and can be individually combined for any application. Because the media can flow both through valves and through the syringe pump, all components are designed for optimum rinsing.

Way of proceeding

Syringe pumps make the exact dosing of small, specific fluid volumes possible. With the motion of a piston inside of the pump cylinder, medium is taken in through suction and dispensed back again. This principle works discontinuously. The pump takes a certain amount of liquid in through suction and dispenses it through the same channel to a needle again.

Application Syringe Pump Dosing

Air Isolated Syringe Pump Dosing

This dosing principle also uses a syringe pump. However, the medium is not sucked into the pump, just into a dosing needle. This method is used above all in applications with very low dosing amounts. An isolating air pocket acting as a barrier is both in the syringe pump as well as in the inlet channel. The medium only comes into contact with the dosing tip, due to the isolating air pocket. This way, the risk of contamination is minimised. This principle makes an integrated cleaning of the dosing tip possible. After the medium is dosed, a valve opens the cleaning channel. The cleaning solution, which is stored under pressure, flows only through the dosing tip and the syringe pump remains free of liquids, even during the cleaning process, thanks to the isolating air pocket.
