Flow-Through Dissolved Oxygen Assembly - Van London

This Dissolved Oxygen system is designed for O₂ measurements in a continuous flow-through environment. The cell and O₂ electrode are designed to be steam sterilized in the autoclave with the electrode installed. The O₂ electrode system is compatible with most common O₂ amplifiers.

This Dissolved Oxygen system is designed for O₂ measurements in a continuous flow-through environment. The Van London - pHoenix Co. flow-through dissolved oxygen cell is available in a 6000 µL flow-through cell with ¼” tube connection.

The flow cell is constructed of 316L stainless steel or ultem plastic. The cell and O₂ electrode are designed to be steam sterilized in the autoclave with the electrode installed.

Dissolved oxygen electrodes are available in both polarographic and galvanic styles to fill all requirements. The O₂ electrode system is compatible with most common O₂ amplifiers.

The polarographic dissolved oxygen electrodes are available without temperature compensation. If temperature compensation is needed, a separate temperature compensator is required. Temperature compensation is not normally required when calibration is made at a controlled temperature.
