Automatic Sampler System Atmospheric - ASSA

Automatic Sampler System Atmospheric - ASSA

Schematics patented ASSA allows the safe, easy and precise automatic reactor sampling at atmospheric pressure.

The ASSA is mounted on the flange of the reactor dip pipe.

In operation, the dip pipe ball valve is opened and the operator activates the ASSA.

Nitrogen (N2) is automatically purged into the system to flush out any stagnant process media contained inside the dip pipe.

The ASSA then automatically pulls a vacuum to extract a sample of the process media and dispense into the collection pot.

Nitrogen is then once again purged into the dip pipe to drain the excess liquid from the system.

When the ASSA cycle is complete, the operator closes the dip pipe ball valve and takes the sample for processing.
