This series of miniature steam sterilizable, combination pH and redox electrodes are designed for small bench-top fermentors and culture apparatus. The electrodes are designed to fit all 12mm and 6mm electrode holders or rubber stoppers used in benchtop fermentors.
This series of miniature steam, sterilizable, combination pH and redox electrodes are designed for small benchtop fermentors and culture apparatus. The electrode was constructed with a 6mm O.D. immersion shaft to conserve space. Compared to the standard 12mm type, it is relatively small, making it desirable for shallow culture flasks and fermentors.
The electrode’s immersion “A” length can be ordered from 25mm to 300mm.
The electrode can withstand steam sterilization up to 130°C and features the pHoenix detachable cable assembly detached during autoclaving.
Electrodes are available with a double junction reservoir. In most cases, the double junction reference reservoir is recommended for long-term stability and life expectancy. A double electrolyte bridge eliminates poisoning caused by certain ions, such as sulfide. Sulfide reacts with silver, forming silver sulfide deposits in the reference junction. The electrode is constructed with an annular ceramic reference junction concentric with the pH bulb. This eliminates clogging problems that normally occur in most electrodes used in fermentation.
The electrodes are designed to fit all 12mm and 6mm electrode holders or rubber stoppers used in benchtop fermentors.
When ordering, specify immersion length “A,” the distance from the penetration point inside the vessel to the probe’s tip.
A detachable electrode cable must be ordered separately.
