Biotech Fluidics: Robust Inline pH Probe

Hits:13   Date: 7/8/2025

Biotech Fluidics announces the mikron 91 - a compact pH probe for inline analytical or preparative chromatography and continuous bioprocessing applications.
 
This robust flow-through sensor delivers accurate, temperature-compensated pH measurements of liquids flowing through either of its two flow cell design options. Both the analytical and preparative versions of the mikron 91 allow a flow rate of up to 1,000 ml/min without building up more than 1 bar (14.5 psi) back pressure. Additional access to the liquid path makes calibration quick and easy.

With a diameter of just 32 mm (1.25”) and a length of only 115 mm (4.5”), the mikron 91 can be installed in almost any application.
 
The mikron 91 contains a fully temperature-compensated pH-meter including a long-life ISFET measuring electrode, plus a KCl or Ag/AgCl reference electrode designed to provide accurate, temperature-compensated measurement of the pH value.
 
The robust measuring cell of the mikron 91 is fully biocompatible and is available certified for use in USP Class VI cleanroom environments.

Designed to enhance your productivity, the mikron 91 not only stores calibration data and the operating time for the measuring and reference electrodes, but also the time exposure for each pH range. This makes predictive maintenance easier and reduces operational downtime. The mikron 91 pH probe is designed to be quick, easy, and low cost to maintain.
 
Mikron detectors are easy to connect as they communicate through and draw power from a single USB-C port. Drivers are provided for several popular chromatography software packages, alternatively an open protocol can be used for customized implementation. The detectors conform to international standards and are CE marked.
