Conventional automated tissue processors are available in two versions: tissue transfer/open up processors and fluid transfer/enclosed processors. Tissue transfer/open processors first grew to become commercially out there inside the 1940s, as well as earliest styles experienced a rotary configuration with mechanical transfer of baskets that contains tissue cassettes from one beaker of reagent to the next, Therefore circling in the ways of dehydration, clearing and infiltration. Specified these design and style Homes, tissue transfer/open processors remain in some cases often called "carousel" or "dip and dunk" processors.
