High Containment Sampling Valve
The Andocksysteme ASAM sampling system is a unique method for obtaining powder or liquid samples under very high containment conditions.
ASAM 1 - "Jar" sample unit for larger sample capture.
The system works similar to their split valve technology - eg. active and passive valves, however, in lieu of a butterfly valve, the ASAM system uses an active ball-half with a cup machined into the ball-half. When the active valve is closed, it forms a near-flush surface into the process equipment. The sample is captured into a small container, typically glass with a protective steel cage. The container is attached to a passive valve.
ASAM 2 - Thief sample unit for small sample capture.
Similar to the design of the ASAM 1 unit except there is no "cup" in the active ball-half to gather powder, instead the active ball-half has a small hole in which a powder thief can be inserted. The hole is made into the "side" of the ball, thus when the active ball-half is closed the hole is hidden away. The thief is held in a plastic tube-bag, which is joined.
The newest method to take a sample under closed conditions with valves below 1µg/m3 based on the split valve principle. ASAM1 is a contamination free sampler for bulk materials, suspensions, liquids and pasty media.
