Precision Fluidics System

To transport and precisely dose minute volumes in the microliter range, we exclusively use syringe pumps and valves with extremely low dead volumes specifically developed for this application.This ensures an exact sample volume, and measurements are performed with precise volumetric accuracy (cells per ml).

The syringe pumps operate in perfect synchronization for the mixing process and flow cytometric measurement with hydrodynamic focusing.

Since the fluids are constantly propelled during measurement and mixing processes, the likelihood of cell-cell interactions and potential blockages is significantly reduced.

Sampling Points

For the reliable use of flow cytometry (FCM) in an industrial environment, an absolutely bubble-free sample collection is crucial. Air or gas inclusions lead to measurement artifacts, unstable signals, or even misinterpretations, as they act like particles in the measuring cuvette or disrupt the volume flow.

The sampling unit developed by ONTRONIX enables the reliable, direct use of flow cytometry in industrial processes. An integrated particle filter protects the measuring technology from contamination, while automatic filter backwashing ensures uninterrupted, continuous operation.

OBA can be configured with up to four sampling units, enabling it to analyze and monitor up to four different samples. This allows for comprehensive process control while maintaining high flexibility.

Optical Mechanical Design

To ensure the reliability of the delicate optical flow cytometry detection in often harsh industrial environments (vibrations, dust, significant temperature fluctuations), we developed a monoblock design.

This allowed us to achieve the necessary mechanical stability and reliability for the measurement technology, originally developed exclusively for laboratory use, even in industrial settings.
