These autoclavable mini oxygen sensor spots come glued onto a rigid glass support, and can thus be used on planar surfaces only.
Use them with chambers/vessels with planar translucent and non-fluorescent walls (e.g. glass, polyester, acrylic etc.). In this way oxygen measurements can be done in a non-invasive and non-destructive way, and the sensor can be sterilized together with the chamber/vessels through autoclavation and without harming the sensor.
To use the sensor spots a fiber optic instrument and an external fiber cable (light guide) is required. The tip of the fiber cable delivers (blue) light to the backside of the sensor spot though the wall (and transparent glue). The front side of the sensor spot is in contact with the media (liquid or gas), e.g. the light is not passing through the media.
There are two ways of fixing the (external) fiber cable over the centre of the (internal) sensor spot:
1) A bare tip fiber cable (OX11150) is used with a special holder to keep it in a fixed position over the spot.
2) A fiber cable with a threaded SMA connector at the tip (OX11160) is screwed onto an SMA adapter (OX11180) that is glued onto the planar wall of your chamber/vessel.
