We care about precision.

Our miniature pumps in laboratory and analysis equipment

Laboratory and Analysis

For many years, miniature pumps from Schwarzer Precision have proven invaluable in stationary laboratory instruments as well as in the smallest portable analysis devices.

With their gas-tight pump heads, our precision products guarantee infallible, high-quality measurement results. Their highly resistant diaphragms and valves withstand even aggressive acids and alkalis.

Low pulsation, excellent controllability and an almost linear characteristic curve ensure trouble-free interaction with the most sensitive measuring sensors.

In addition, all parameters of our pumps can be precisely adapted to each individual application. Above all, every pump that leaves our factory is 100% tested.


Application Story

Serving science: our SP 270 EC diaphragm pump in a pipetting robot from SEED Biosciences

Cell isolation processes form the basis of cell biology research and technology.

Our customer SEED Biosciences has developed a new cell isolation procedure and is implementing it using a new pipetting robot.
This innovative laboratory instrument was developed by scientists for scientists and is able to accurately dispense single cells.

This allows scientists to carry out cell line developments or investigations into the unique properties of single cells more reliably and with more traceable results than with previous methods.

In addition to the flow rate being specifically tuned to the system‘s working point, SEED Biosciences wanted the pump to be capable of being mounted directly on the printed circuit board.

Thanks to the particularly low-vibration of our diaphragm pump and a vibration-reduction mounting element specially developed by us for the pump, our SP 270 EC could finally be mounted and operated directly on the printed circuit board without disturbing the sensitive electronics.

Our engineers derived the specific working point from the modular system quickly and reliably.
