Reagent administration Processing answers inevitably turn out to be ever more impure and dilute with use because of gradual contamination of processing remedies each via the tissues and through the preceding Remedy during the processing sequence. It is actually as a result needed to periodically transform options as a way to realize high quality tissue processing. To extend the handy life of reagents and thus assistance have expenses, reagents can even be rotated to an earlier situation inside the processing sequence. For illustration, if 3 xylene baths are useful for clearing, soon after several operates the xylene in the first container is discarded, the next xylene container is moved to placement a single, the third xylene container is moved on the place two, along with a fresh xylene container is inserted into position 3.
