These housings incorporate the latest B. Braun Biotech design requirements and are not only compatible with the new 25 mm safety ports, but also with older 25 mm port designs.

When this housing design is used with the new B. Braun Biotech safety port, the port will release any internal steam pressure in the vessel before the housing is completely disengaged from the port.

The pH electrode is secured to the housing by a free-spinning threaded retainer nut. This allows the electrode to be installed and removed from the housing without twisting or disconnecting the electrode cable.

How to Order a Housing

Confirm the vessel has a B. Braun Biotech 25 mm side port.
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 process applications except when media is highly viscous. Highly viscous media is prone to clog the guard area of the housing.
Choose a steam sterilizable pH electrode from among the FermProbe models F-615, F-607 and F-600. These rugged process pH electrodes secure to the housing with a free-spinning threaded retainer ring.
