Re-usable-Sensors (SUS) in Single-Use-Well
Hamilton manufacture the VisiFerm™ optical oxygen sensor with 0-300% saturated O2 range. PerfuseCell manufacture and install optionally (before bagging and E-beam irradiation) the non-invasive transparent Polycarbonate VisiWell with the unique optical active black spot.
The user insert their own re-usable VisiFerm™ DO sensor (without stainless-steel end-cap) into the non-invasive VisiWell. There is no contact between VisiFerm and the media. No autoclaving of VisiFerm is required insuring the sensor obtain a long and stable lifetime.
The two VisiFerm models wich fit the P-SUBs are model 120 and 220. Both analogue and digital (ARC) VisiFerm versions works.
Calibration according to Hamilton recommendations: http://www.hamiltoncompany.com/Sensors - which is:
- Insert VisiFerm in the VisiWell, fill P-SUB with media, maximum aeration specified for the P-SUB and calibrate traditional at 100% saturation.
- Calibration of the VisiFerm with air, before media is filled in the P-SUB.
