The Model F835 steam sterilizable and autoclavable pH FermProbe® is built to withstand repeated high temperature sterilization by pressurized steam. The Pg13.5 cap design provides for insertion and removal of the electrode from its housing.
Each FermProbe is steam sterilized for one hour at 135°C before final QA tests in order to insure the highest level of electrode reliability.
All FermProbes have two built-in electrolyte chambers that act to protect and isolate the sensitive inner AgCl reference half-cell. This “double junction”, dual chamber design effectively prevents the most common failure modes of pH electrodes in bio-pharmaceutical applications.
Metric FermProbe pH Electrodes
This FermProbe style features a metric Pg13.5 threaded polymer cap that allows it to be used with European style electrode housings. Autoclavable as well as steam sterilizable, this style of pH FermProbe is the first choice for use with small autoclavable benchtop vessels. Available only in the disconnect cap style. Cables must be ordered separately.
