The pH SensorPlug has been specifically designed for non-invasive measurement of pH in millifluidic and microfluidic applications. With a Mini Luer interface, it can be easily integrated into microfluidic chips for online monitoring of pH. These sensors are sold in packs of 10 units. 

In the SensorPlug, the optical pH sensor is attached to a Mini Luer plug, for easy integration in microfluidic chips via the corresponding Mini Luer port. This allows for non-invasive measurement of pH (5.5 -8.5 pH) in millifluidic and microfluidic experiments, without any risk of contamination.

SensorPlugs are delivered beta-irradiated and pre-calibrated for immediate use. The pH SensorPlug can be combined with CO2 and O2 SensorPlugs and measurements can be controlled from one computer via the PreSens Measurement Studio 2 software.

The SensorPlugs can be integrated into fiber sensor integration chips and multi-organ platforms from ChipShop. 

The complete setup for PreSens technology includes a meter, a sensor, and relevant accessories including the optic fiber. These components can easily be integrated to any microfluidics and organ-on-chip experiments. 

Components for PreSens sensing technology

Optical sensors offer several advantages that render them particularly well-suited for controlling small sample volumes:

  • They are small
  • The signal does not depend on the flow rate of the sample 
  • They allow for non-invasive measurement
