Typically a benchtop application is less than 5 L, and uses a
glass vessel or flask. Usually the entire vessel can be placed or
wheeled into an autoclave for sterilization prior to a run. Not
only is there a wide range of different vessel sizes used in
benchtop bioprocess applications, but also the volume of the
media in the vessel will often change during the process.
Accordingly, the sensors for benchtop vessels are available in
a wide variety of lengths. The operator must cho
ose a sensor
length that ensures that the sensor tip is submerged at all
times during operation. Some sensor models have been con-
figured to thread directly into the headplate and various
access ports found on small vessels. Detachable cables and
other design features allow these products to withstand the
demands of autoclaving requirements.
