ABSTRACT:
A sort block for use with sorting flow analysis system. The sort block includes a fin extending into a sort stream in the sort block. Unsorted particles and aerosol are aspirated into the open top of the fin. When error is detected, collection baskets associated with the fin extend into the sort stream, block passage of particles to the collection containers and aspirate all droplets and aerosol to a waste or retrieval container. This sort block may include error monitors, such as a laser and camera combination, which monitor the flow stream and control the extension of the fin and basket type collector.
