Can I re-use the SensorVials?

Yes, the SensorVials can be cleaned with ethanol and re-used. Please make sure to dry the SensorVials thoroughly after washing them with ethanol (at least 2 days at 50 °C in a drying chamber). Otherwise, the sensor will show too high oxygen levels. If you wash the SensorVials with water only, please make sure to use ethanol from time to time to avoid contamination with bacteria.
