Oxygen Monitoring in 20 mL Vial with Autoclavable Oxygen Sensor
SensorVial SV-PSt3-20mL-YST
The SensorVial is a 20 mL glass vial with an integrated optical oxygen sensor stripe. It is connected to the transmitter by an optical fiber. With the Vial Adapter the optical fiber can be positioned in different heights for oxygen measurements. The SensorVial SV-PSt3-20mL-YST is autoclavable, and the ideal tool for respiration measurements. Since the sensor spots are optically isolated with a black layer they are also very well suited for photosynthesis measurements. For non-stirred applications vials with a sensor stripe, that reaches all the way to the bottom are also available. Oxygen can be measured simultaneously in liquid and headspace.
- Non-invasive online oxygen measurements
- No consumption of oxygen
- Signal independent of flow velocity
- Oxygen measurements in liquid and gas phase
- Autoclavable
Applications
Respiration & Photosynthesis: Oxygen Monitoring in Glass Vials
Determination of respiratory activity is often performed for water organisms such as invertebrates, larval stages or eggs, but also for bacteria, cell cultures, yeasts or fungi. For algae measurement of photosynthetic activity is of great interest. Using our 20 mL SensorVial with an integrated sensor stripe oxygen can be measured simultaneously in the liquid sample and in the headspace. Autoclavable SensorVials for stirred and non-stirred applications are available.
