| |  | | | Biotechnology Replacement stainless steel oxygen probes for fermentation High Quality Replacement Electrodes for your favoritedissolved oxygen fermentation equipment at very competitiveprices. Why pay full price when you can get these premium dissolvedoxygen electrodes at a fraction of the price? Features- Steam Sterilizable. The steam sterilizable family of dissolved oxygen electrodesis specifically designed for fermentation where it isnecessary to subject electrodes to repeated steamsterilization.
- Polarographic/Galvanic. Dissolved oxygen electrodes are available in bothpolarographic and galvanic styles to fulfill allrequirements. laboratorymart.com electrodes are compatible with mostcommon O2 amplifiers found in fermentation. Polarographicelectrodes are designed to be used with Ingold IL(R), Cole-Parmer(R) and Applikon(R) O2 amplifiers, or with otheramplifiers that are designed to be used with Ingold(R)dissolved oxygen electrodes.
- Galvanic electrodes are designed to be used with NewBrunswick Scientific(R), LSL Biolafitte(R) and Applikon(R) O2amplifiers.
- Insitu Sterilization. The DO probes are available for laboratory fermentationwhere sterilization takes place in a separate autoclave orindustrial applications where sterilization takes place insitu.
- Unique Membrane Cartridge. The easily replaced electrode membrane cartridge is a uniquefeature of the laboratorymart.com polarographic and NBS galvanicdissolved oxygen electrode. The membrane is of specialconstruction -- a silicone and fluoropolymer composite,reinforced with stainless steel mesh. This unique membrane is veryrugged and allows for repeated sterilization without damage,allowing it to withstand severe conditions. The electrodeoperates 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. Theelectrolyte can be replenished or filled during use withoutremoval from the vessel. The electrode is constructedinternally with a pressure compensated electrolyte chamber.The filling tubes on this electrode are closed and keptinside the probe during sterilization and use. Biolafitte(R)type galvanic dissolved oxygen electrode features easilyreplaceable FEP fluoropolymer membranes with external electrolytefilling tubes.
- Temperature Compensation. The polarographic dissolved oxygen electrodes are availablewith or without automatic temperature compensation. Theyare designed to match the Ingold IL(R) oxygen amplifier.Temperature compensation is not normally required whencalibration is made at the same temperature as thecontrolled fermentation temperature with no variation.
