Sampling Bottle System

Supplier: Gemu Australia

The objective of GEMÜ products is increased safety for the sampling of liquids from sterile and hygienic processes.


The valve block systems on the tapping point and on the sampling bottle have an EHEDG diaphragm sealing system made from FDA-compliant materials. Due to the multi-way solution, this system is both sterilisable and autoclave-capable.

The valve body is made from stainless steel (1.4435 or 1.4435 with a ferrite content under 0.5 per cent), glass or stainless steel can be used as the bottle material.

The bottles can either be provided separately or supplied as an overall package (stainless steel bottle 1.4404, Schott Duran Pressure plus glass bottle). The maximum capacity in the GEMÜ sampling bottle system is 1000 ml. As standard, the seals are made from PTFE, EPDM or FEP; other materials are available on request.

As standard, the valve bodies enable the following functions:

  1. Pneumatic or manual operator
  2. Sampling connection and CIP/SIP inlet
  3. Bottle filling
  4. CIP/SIP outlet
  5. Vent hole

Due to the flexibility in the design of GEMÜ block systems, these functions can be offered with different geometries. Other functions can also be integrated on request.
