DO sensor well

Choose a DO Single-Use-Well pre-installed

Single-Use-Well (SUW) allow installation of non-sterile DO sensor's. The SUW (VisiWell and/or PolarWellis integrated along with assembling of SUB/SUF before bagging and subsequent E-beam irradiation. Dry storage capability is 18 month on SUW components stored below 20° and with no UV light exposure.


VisiWell™ for exceptionally simple use with the VisiFerm™ optical oxygen sensor range 0-300% saturated.

  • In-house manufactured and installed VisiWell non-invasive Single-Use-Well (SUW) with the unique optical active spot on the polymer end-cap.
  • The user insert their own re-useable VisiFerm™ DO sensor (without Stainless Steel end-cap) into the non-invasive SUW - that's all! VisiWell™ format is for standard PG 13,5 x 120, 220, 320 mm size VisiFerm.

VisiFerm™ optical DO sensor is available in the analogue version and the digital version. Here both shown in 120 mm and 220 mm long versions and both with VP8 connector.


PolarWell™ for very simple use with most brands of Polarographic, Ampheometric principle DO sensor's.

  • In-house manufactured and installed PolarWell non-invasive Single-Use-Well (SUW) with a unique semi-permeable silicone membrane end cap.
  • End-user insert their own DO Re-Useable-Sensor (RUS) into the non-invasive SUW. 
  • No extra liquid is needed. No removal of sensor cap is required. 
  • PolarWell™ format is for standard PG13.5 x 120, 220 mm size DO RUS.

Shown with typical 4 wire T82 / D4 classical type of socket. An adapter converting from T82 / D4 to VP12 is available.
