Dialysis Probe

Dialysis Probe - volume free online sampling

The TRACE dialysis probe provides the perfect solution for sterile online sampling in connection with the online analyser TRACE C2 Control, TRACE M4 and MultiTRACE as well as the online bioreactor sampling system TRACE C2 Sampling

The dialysis probe is installed in the bioreactor and can be sterilized in situ. It can be used in industrial as well as laboratory facilities.
The probe can also be used in single-use bioreactors via a Kleenpak™-Adapter.
