STANDARD 25 mm SIDE PORT
Found on nearly all vessels other than those manufac-
tured by B. Braun Biotech. The port bore is 25 mm i.d.
and the housing o-ring seals to the inside of the port.
The housing is then secured to the port by a threaded
retainer ring. The port is installed at a 15° angle for bet-
ter electrode performance. See the cutaway drawing to
the right for typical installation dimensions.
The electrode housing is designed to hold and protect the
pH electrode while inserting it into the bioprocess vessel.
There are various types of side entry ports and dierent
gr
oups of housings to t each port type. The size and make
of the port must rst be identied in order to narrow the
selection process.
The two most common types of entry ports found on
pilot and production scale vessels are as follows:
B. BRAUN BIOTECH 25 mm SAFETY SIDE PORT
Found exclusively on vessels manufactured by B. Braun
Biotech. This style of port is longer than the standard port
and needs a special housing to t correctly. (Note: The
port opening on newer tanks is 30 mm i.d. and the port
narrows down to 25 mm i.d. at the critical point where the
ho
using o-ring seals to the inside wall of the port.) Again,
the port is installed at a 15° angle for better electrode per-
formance. See the cutaway drawing to the right for typi-
cal installation dimensions.
