Glass Body Dissolved Oxygen Electrodes - Van London

The glass body Dissolved Oxygen electrodes are available for laboratory fermentation, where sterilization takes place in a separate autoclave. The disposable Van London - Phoenix Co. Dissolved Oxygen Electrodes are compatible with most common oxygen amplifiers.

This series of steam sterilizable, Dissolved Oxygen electrodes are designed for economical use. They are constructed very similarly to the standard pH electrode, and have a 10 and 12mm body, and can be ordered with the desired “H” length. The “H” length is determined by the insertion depth on the under side of the fermentor headplate to the tip of the probe. Glass disposable Dissolved Oxygen electrodes are available in both polarographic and galvanic styles to fit all requirements.

The glass body Dissolved Oxygen probes are available for laboratory fermentation, where sterilization takes place in a separate autoclave. The disposable Van London - Phoenix Co. Dissolved Oxygen Electrodes are compatible with most common oxygen amplifiers. Glass body Dissolved Oxygen electrodes are non-temperature compensated and are required to be kept at a constant temperature. Calibration must be made at the same temperature as the controlled fermentation. The electrodes feature external filling tubes. Electrolyte can be added during use without removing the electrode from the vessel. The electrode membranes can be replaced very easily. However, some skill is involved in replacing them.
