Dissolved Oxygen Electrodes
DISSOLVED OXYGEN ELECTRODES _________________________________________________
The steam sterilizable family of dissolved oxygen electrodes from the pHoenix Electrode Company is
specifi-cally designed for fermentation where it is necessary to subject electrodes to repeated steam sterilization.
Dissolved oxygen electrodes are available in both polarographic and galvanic styles to fulfill all requirements.
pHoenix O
2electrodes are compatible with most common O
2amplifiers found in fermentation. Polarographic
electrodes are designed to be used with pHoenix Electrode Company, Ingold IL, Cole-Parmer and Applikon O
2amplifiers, or with other amplifiers that are designed to be used with Ingold dissolved oxygen electrodes.
Galvanic electrodes are designed to be used with pHoenix Electrode Company, New Brunswick Scientific, LSL
Biolafitte and Applikon O
2amplifiers.
The DO probes are available for laboratory fermentation where sterilization takes place in a separate autoclave
or industrial applications where sterilization takes place in-situ.
The easily replaced electrode membrane cartridge is a unique feature of the pHoenix polarographic and NBS
galvanic dissolved oxygen electrodes. The membrane is of a special construction - a silicone and teglon
composite, reinforced with stainless steel mesh. This unique membrane is very rugged and allows for
re-peated sterilization without damage, allowing ot to withstand severe conditions. The electrode operates
with-out maintenance for 5 to 10 sterilizations, fermentation cycles or, in terms of time, for 6 to 8 weeks. The
pHoenix Biolafitte type galvanic dissolved oxygen electrode features easily replaceable FEP teflon
mem-branes.
The polarographic dissolved oxygen electrodes are available with or without automatic temperature
compensa-tion. They are designed to match the Ingold IL oxygen amplifier. Temperature compensation is not normally
required when calibration is made at the same temperature as the controlled fermentation temperature with no
variation.
