These unguarded housings incorporate the latest Sartorius (B. Braun Biotech) requirements and are designed to be used with models F-235, F-285F-635, F-695, F-835, F-895 Metric FermProbes® and models D540 or D545 12 mm OxyProbe® II dissolved oxygen sensors, they can also be used with any 12 mm sensor that has Pg13.5 threads. The housings can be used with both the new 25 mm safety ports and the older 25 mm port designs.

346 unguarded housingWhen these housings are used with the Sartorius (B. Braun Biotech) safety port, the port will release internal steam pressure in the vessel before the housing is completely disengaged from the port. The metric FermProbe pH electrodes thread directly into the 346 style housing, eliminating the need for a threaded retainer nut. In order to prevent twisting the cable, the metric FermProbes have a detachable cable.  This feature is very helpful when calibrating the pH electrode tank side in a production environment.

A guarded version is also available (see model 356). Using a guarded housing is highly recommended for pH electrodes to provide maximum protection against damage to the sensing bulb. However, highly viscous media is prone to clog the guard.

Specification

  • 316L stainless steel construction.
  • Serialized for traceability to mill steel specifications.
  • RA32 finish with electropolish on all wetted parts.
  • FDA compliant external EPDM o-rings.
  • Permanently secured port retainer ring for additional operator safety.

Additional Features

  • Guarded versions for rugged handling while protecting the pH glass bulb in a production environment.
  • A guarded version for viscous media is also available (model 356).
  • Custom designs and custom modifications promptly quoted.

  1. Confirm that the vessel has a B. Braun Biotech 25 mm side port (for assistance with this please see our FAQ for ‘How do I choose a housing style‘.
  2. Determine whether the application will permit the use of a bulb guard on the housing. The bulb guard design is highly recommended for all types of applications except where media is highly viscous. Highly viscous media is prone to clog the guard area of the housing which can cause erroneous measurements. If the application will permit the use of a bulb guard then please see Model 356 Guarded Housing instead.
  3. Choose the correct steam sterilizable FermProbe pH electrode from the models  F-235, F-285F-635, F-695, F-835, F-895 Metric FermProbes® and models D540 or D545 12 mm OxyProbe® II dissolved oxygen sensors.
