pH Sensors

pH+ sensor, gel-filled, sterilizable.

In the biotech- and pharmaceutical industry it is vital to have precise information
about the pH value of the bioprocess. The pH directly affects productivity, stability
and analysis of the active ingredients.
In a bioreactor / fermenter, the environmental conditions for cells or microorganisms should be optimal.
The AppliSens pH+ sensor is the ultimate pH sensor for bioprocess measurement.
The pH+ sensor has a fixed sleeve diaphragm. Compared to other diaphragm
types, the sleeve diaphragm gives increased measuring accuracy and precision, resulting in excellent performance:

  • No cross contamination
  • Precise calibration
  • Not sensitive to fouling
  • No need to recalibrate
  • Low and constant offset
  • Stable signal over time

The sensor is constructed using FDA approved materials, like the non-toxic solid gel
electrolyte. Furthermore this sensor has an internal pressure, which reduces cross
contamination. The pH sensor is designed to withstand repeated sterilization cycles
without failure.
AppliSens sensors have a Long-Life code print (engraved serial number) on the
sensor head and are accompanied by a certificate (good for validation; FDA / GLP).

The electrode has a 12 mm body and a PG13.5 connector and fits into any standard
sensor holder.
