Reagent administration Processing solutions inevitably come to be significantly impure and dilute with use because of gradual contamination of processing alternatives both via the tissues and via the previous Option within the processing sequence. It is actually for that reason important to periodically improve options in an effort to reach top quality tissue processing. To lengthen the beneficial life of reagents and thus assist consist of expenses, reagents can even be rotated to an before position inside the processing sequence. For example, if 3 xylene baths are useful for clearing, following numerous operates the xylene in the main container is discarded, the 2nd xylene container is moved to position a person, the 3rd xylene container is moved into the placement two, and also a fresh xylene container is inserted into position a few.
