BioCheck sampling in bottle (accessory)

With the BioCheck sampling system, samples can be taken easily and safely from closed systems such as containers and pipes. When designing this sterile fitting, particular emphasis was placed on the aseptic but also very compact design, so that it can be integrated into both sterile and CIP/SIP circuits without any problems and, above all, without contamination.

Withdrawal procedure
  1. The product flows through the pipe. The BioCheck sampling valve (3) and CIP/SIP valve (1) are closed.
  2. After the bottle has been sterilized in the autoclave, connect the bottle to the sampling outlet.
    Both valves of the bottle (valve (5) and valve (6)) are closed.
  3. Open the CIP/SIP valve (1) and the straight-through valve (5) for cleaning.
    The steam sterilizes and rinses the entire system, but not the bottle.
    This was previously cleaned in an autoclave (see 2.).
  4. Close the CIP/SIP valve (1) and the straight-way valve (5).
  5. Open the BioCheck sampling valve (3) and the valve for sampling into the bottle (6). The product flows into the bottle.
  6. First close the BioCheck sampling valve (3).
  7. After the outlet for sampling (4) has run empty, close the valve for sampling into the bottle (6) on the bottle.
    The entire system is closed.
  8. Remove the bottle from the system for sampling.
