This is the standard Broadley-James metric FermProbe connector. This FermProbe style has been used as a standard for years. It is designed to be used in bioprocess applications where CIP/SIP procedures are used. The metric FermProbe will withstand multiple autoclaving or sterilization cycles, however, an autoclave cap should be used when autoclaving the electrode.

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

  • Metric threaded cap is compatible with nearly all European designed bioprocess electrode housings.
  • Steam sterilizable and autoclavable.
  • First choice for use with small autoclavable vessels.
  • Available in variety of lengths for different insertion length requirements and applications.

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-635 pH electrodes require disconnect cable and connector assemblies.
