Product summary

The Air-driven OEM Single Channel Pipetting Head with integrated flow sensor is suited for liquid handling in sub-microliter to milliliter volume range.

This product has been designed to fit a wide range of applications where action validation and process surveillance is required. The use of a dedicated MEMS flow sensor at the pipetting site allows complete validation of aspiration and dispense actions in real time, as well as providing clogging detection and other process monitoring information.

The Pipettor operates with a pressure/vacuum source, typically in the range of ± 200 mbar gauge for aspiration/dispense pressure. The pressure controller further acts as System Controller by providing a single port access from the host computer. Integrated high level coordination between the pressure source and the pipetting unit allows an efficient and rapid integration of the unit onto our customer’s automated platforms.

Operating Principle

Aspiration and dispense of the liquid sample is driven by vacuum and positive pressure.



An inlet port provides aspiration/dispense pressure to the channel. A solenoid valve is coupled to a silicon MEMS flow sensor that controls the pipetted volume and allows precise tracking of the operation of the channel.

The Flow sensor and the control electronics provide precise Liquid Level Detection (LLD). The LLD signal can be read via a hardware line. Triggering of pipetting actions can be driven via a hardware line, in addition to being operable via software command on the serial line. A wide range of applications can thus be rapidly implemented.

The Technology

Seyonic Sensor Controlled Pipetting systems provide accurate and precise liquid handling in the microliter to milliliter volume range. Operation is controlled through measurement of displaced air volumes by means of a flow sensor, integrated directly in the pipetting head, in connection with a high-speed solenoid valve.
