Fiber Optic ATR-Probes (Shaft-in-shaft design)

Main features

Fiber assembly is easy detachable.
No need to retract the whole probe out of the fermenter, just pull the fiber assembly out of the operational shaft and store it separately.
Sealing the operational shaft is possible for the sterilization, cleaning, deactivation or any other treatment.
