The new F-835 offers the same form, fit and function as the F-635 with improved performance and USP Class VI materials. The unique construction methods used by Broadley-James allows this SIP and autoclavable pH electrode to exhibit virtually zero drift sterilization.

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.

Features

  • Double-Junction Silver/Silver Chloride reference element for the ultimate in stability and resistance to contamination.
  • Specifically designed for multiple SIP, CIP, or Autoclave cycles.
  • Withstands exposure to harsh CIP solutions.
  • Metric threaded PG13.5 cap is compatible with a wide range of bioprocess electrode housings.
  • Rugged, low-impedance pH bulb provides fast and precise pH measurements even after prolonged steam exposure.

Specifications

  • 0 – 13 pH range
  • Steam sterilizable to 135° C
  • 150 psig max. pressure
  • Double junction, Ag-AgCl reference system
  • Metric Pg13.5 threaded disconnect cap

Choose Electrode Model

If the electrode needs to fit an existing cable, check cable connector. If it has a male connector, an F-635 or F-835 FermProbe is required. Another guideline is to note the connector’s color. If the cable connector is black, use the F-635 or F-835 Fermprobe.

Choose Electrode Length

Benchtop Applications

The electrode length is from the base of the cap to the tip of the electrode (the glass part of the electrode).

SIP Tank Applications

If you have already chosen a housing, select an electrode length with the same Class designation as the housing. The housing ordering information box also lists the correct electrode length to order. If you have not already chosen the housing, please review the recommendations next to each electrode model below.

Confirm Cable Length and Connector

Model F-835 pH electrodes require disconnect cable and connector assemblies.
