The monitoring and control of Dissolved Oxygen is one of the major parameters in a biotechnological process. This is true for fundamental research as well as for fermentation and cell culture process research. AppliSens DO sensors are manufactured using state-of-the-art technology and are delivered factory tested with membrane module in place.

Two types are available:

Sterilizable 4-pin DO sensor
The sterilizable 4-pin DO sensor is provided with an integrated NTC. This NTC can be applied when the polarographic DO amplifier is provided with the feature of automatic temperature compensation (ATC). The 4-pin DOsensor is available in various insertion lengths:
  • 70mm for DN25 ports (S.I.P. reactors)
  • 190mm -­ 590mm

LowDrift DO sensor
The LowDrift DO Sensor offers a guaranteed low drift and does not have an integrated NTC. The LowDrift DO sensor has a cable connection which is identical to the (K9) connector as used with the pH sensors and is available in various insertion lengths:
  • 65mm -­ 590mm

All AppliSens DO sensors feature:
  • High-grade finish to facilitate cleaning (C.I.P.) electropolished surface (Ra < 0.8 µm).
  • Shaft diameter 12mm
  • All electrodes are delivered with a certificate: good for GLP / GMP
  • Long-Life serial code engraving on sensor head: good for GLP / GMP
  • Stable current, broad linearity even after repeated sterilization
  • Applicable with all current available polarographic amplifiers
  • The sensor can be mounted into virtually any brand of autoclavable or S.I.P. bioreactor
  • A high-quality, low-noise cable standard is available for this sensor

The LowDrift sensor has the extra's like:
  • a free spinning PG13.5 connector: easy mounting
  • applicable in most commonly used sensor holders like EasyFix, TracFix a.o.
