Cold Trap, two Sections

A special version is the two section cold trap. It has a KF NW 50 flange as the connection part. This type of cold trap enables the condensation area to be separated from the upper section of the cold trap. This ensures that the removal of the condensation and the cleaning of the cold traps can be carried out very easily. This version is also suitable for when a cold trap has to be permanently installed inside an apparatus, so that only the lower section of the cold trap has to be removed in order to empty out the condensation. The KF NW 50 flange connecting piece is secured in place using a spring Aluminium clamp and this is included in our scope of delivery.
