Respiration Measurements in Glass Vials with the SDR SensorDish® Reader
SensorVial SV-PSt5-20mL
The 20 mL glass vials are equipped with an oxygen sensor type PSt5 at the bottom. This sensor is read out with the SDR SensorDish® Reader. The SV-PSt5-20mL are used with the Mask for SensorVials SDR-MSV12-20ML, which holds up to 12 of the vials in the correct position on top of the SDR SensorDish® Reader for sensor read-out. The integrated sensor is optically isolated, so the sensor can be used at ambient light and even artificial light. SensorVials are ideally suited for respiration and photosynthesis monitoring of small aquatic organisms. The Mask SDR-MSV12-20ML shields the reader optics from ambient light and allows using the SensorVials even for photosynthesis experiments (up to 50 % O2). The vials can be cleaned with ethanol or mild detergent and are re-usable.
- Contactless online oxygen monitoring
- Parallel measurements
- Re-usable
- Ideal for respiration and photosynthesis monitoring in plant and animal physiology
Applications
Real-time Monitoring of the Respiration of Marine Zooplankton
Oxygen consumption of 3 - 4 copepod nauplii per sample was monitored in air-tight glass vials for 6 h. The nauplii were offered phytoplankton at environmental concentrations. Feeding and faecal pellet production rates were estimated simultaneously. The respiration rates were linear and steady, thus revealing that the nauplii were neither influenced by the vessel walls nor by diminishing of food. The respiration rate was compared to literature values of other species.The higher oxygen consumption of the nauplii was presumably due to constant feeding.
