Glass Body Low Cost 
Disposable DO Electrodes
 
 
This series of steam sterilizable electrodes is designed for economical use. They are constructed very similarly to the standard pH electrodes, have a 10 and l2mm body, and can be ordered with the desired "H" length. "H" length is determined by the insertion depth on the under side of the fermentor headplate to the tip of the probe. Glass disposable electrodes are available in both polarographic and galvanic styles to fill all requirements. 

The glass DO probes are available for laboratory fermentation, where sterilization takes place in a separate autoclave. The disposable pHoenix Dissolved Oxygen Electrodes are compatible with most common oxygen amplifiers found in fermentation. Glass body 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. 

The polarographic type electrodes are to be used with Ingold, pHoenix amplifiers or amplifiers from other manufacturers designed to be used with Ingold DO electrodes. The galvanic type electrodes are designed to be used with NBS, LSL Biolafitte and pHoenix Electrode Co. amplifiers.
