DO Sensors

DO2 Sensors

Dissolved Oxygen sensor, Low Drift, sterilizable.

The majority of all biotechnological processes are of the aerobic kind.
A microorganism or cell responds to the liquid phase oxygen concentration
in regulating its overall metabolism. Therefore the knowledge of the DO
concentration and the proper control during the process are of great importance.

  • The AppliSens Low Drift DO sensor offers a guaranteed low drift.
  • Features:
  • The sensor is constructed using FDA approved materials
  • Cable connector, identical to the one as with the pH sensor
  • 12mm diameter body
  • PG13.5 connector, free spinning (easy mounting)
  • a Long-Life code print (engraved serial number) on the sensor head
  • Optimal cleanability (fully electropolished surface)
  • each sensor is accompanied by a certificate(good for validation; FDA / GLP).

The AppliSens DO sensors are specifically designed for fermentation and cell culture application and designed to withstand repeated sterilizations without failure.
The Low Drift DO sensor is based on the principle of the Clark cell and can be used in combination with any brand polarographic type of amplifier.

The combination of a small cathode with a composite membrane along with
a highly permeable reinforced silicon membrane results in:

  • low flow dependency
  • good response time
  • high mechanical strength
  • maintenance free operation over several months
  • simple maintenance
