Robust inline pH probe

23 Sep, 2025

The mikron 91 from Biotech Fluidics is a compact inline pH probe for 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.
