Durable flow-through pH probe

Biotech Fluidics introduces the mikron 91, a compact and durable inline pH probe designed for analytical and preparative chromatography, as well as continuous bioprocessing applications.

This advanced flow-through sensor provides precise, temperature-compensated pH measurements of liquids passing through its two available flow cell designs. Both the analytical and preparative mikron 91 variants support flow rates up to 1,000 ml/min, maintaining back pressure below 1 bar (14.5 psi). Easy access to the fluid path simplifies calibration, ensuring minimal disruption during maintenance.

Measuring just 32 mm (1.25”) in diameter and 115 mm (4.5”) in length, the mikron 91 fits seamlessly into a wide range of process setups.

The probe houses a fully temperature-compensated pH meter featuring a durable ISFET measuring electrode alongside either a KCl or Ag/AgCl reference electrode. This combination guarantees reliable, accurate pH readings under varied operating conditions.

Constructed with a biocompatible measuring cell, the mikron 91 is certified for use in USP Class VI cleanroom environments, making it suitable for stringent pharmaceutical and biotech processes.

Designed to boost operational efficiency, the probe stores key data including calibration history, electrode operating times, and exposure durations across different pH ranges. This enables predictive maintenance, helping to reduce downtime and control costs. Maintenance of the mikron 91 is straightforward, quick, and economical.

Connectivity is streamlined via a single USB-C port that supplies both power and communication. Compatible drivers are available for leading chromatography software, with an open protocol option for custom integration. The mikron 91 complies with international standards and carries CE marking.
