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?
Features
- 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. laboratorymart.com 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 laboratorymart.com 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.
