Replacement stainless steel oxygen probes for fermentation

Replacement stainless steel oxygen probes for fermentation

High Quality Replacement Electrodes for your favorite dissolved oxygen fermentation equipment at very competitive prices.

Why pay full price when you can get these premium dissolved oxygen electrodes at a fraction of the price?

  • Steam Sterilizable. The steam sterilizable family of dissolved oxygen electrodes is specifically designed for fermentation where it is necessary to subject electrodes to repeated steam sterilization.
  • Polarographic/Galvanic. Dissolved oxygen electrodes are available in both polarographic and galvanic styles to fulfill all requirements. electrodes are compatible with most common O2 amplifiers found in fermentation. Polarographic electrodes are designed to be used with Ingold IL(R), Cole- Parmer(R) and Applikon(R) O2 amplifiers, or with other amplifiers that are designed to be used with Ingold(R) dissolved oxygen electrodes.
  • Galvanic electrodes are designed to be used with New Brunswick Scientific(R), LSL Biolafitte(R) and Applikon(R) O2 amplifiers.
  • Insitu Sterilization. The DO probes are available for laboratory fermentation where sterilization takes place in a separate autoclave or industrial applications where sterilization takes place insitu.
  • Unique Membrane Cartridge. The easily replaced electrode membrane cartridge is a unique feature of the polarographic and NBS galvanic dissolved oxygen electrode. The membrane is of special construction -- a silicone and fluoropolymer composite, reinforced with stainless steel mesh. This unique membrane is very rugged and allows for repeated sterilization without damage, allowing it to withstand severe conditions. The electrode operates without maintenance for 5 to 10 sterilizations, fermentation cycles or, in terms of time, for 6 to 8 weeks.
  • External Filling Tubes. The electrode features external filling tubes. The electrolyte can be replenished or filled during use without removal from the vessel. The electrode is constructed internally with a pressure compensated electrolyte chamber. The filling tubes on this electrode are closed and kept inside the probe during sterilization and use. Biolafitte(R) type galvanic dissolved oxygen electrode features easily replaceable FEP fluoropolymer membranes with external electrolyte filling tubes.
  • Temperature Compensation. The polarographic dissolved oxygen electrodes are available with or without automatic temperature compensation. 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.
