Automated and Rapid Tissue Processing Flashcards
makes use of an automatic tissue processing machine that fixes,
dehydrates, clears and infiltrates tissue
AUTOMATED TISSUE PROCESSING
decreases time (approximately 16 hours) and labor needed during tissue processing → more rapid diagnosis with less technicality
AUTOMATED TISSUE PROCESSING
COMPONENTS OF TISSUE PROCESSORS
- ELECTRICAL TIME CLOCK
- CIRCULAR SUPERSTRUCTURE
- TRANSFER ARM
- RECEPTACLE BASKET
- CIRCULAR DECK
- BEAKERS
- WAX BATH
controls the time intervals in the immersion and transfer of
tissue samples from one reagent to another
ELECTRICAL TIME CLOCK
contains the basket carrier, receptacle basket and receptacles
CIRCULAR SUPERSTRUCTURE
moves the tissues from one processing reagent to another
TRANSFER ARM
holds the specimen
RECEPTACLE BASKET
holds the reagent beakers and paraffin wax baths
CIRCULAR DECK
contain the reagents
BEAKERS
contains the paraffin
WAX BATH
CARE OF THE TISSUE PROCESSOR
✓ Change reagent solutions depending on the number and sizes of tissue samples being
processed in the laboratory
✓ Presence of odor, contamination or cloudiness in a reagent solution indicates that
changing is required
✓ Wax baths should be filled to the appropriate level
✓ Accumulated wax in beakers or on any surface of the machine must be removed and
any spillage should be wiped
✓ Receptacles and baskets are cleaned of residual paraffin by immersion in xylene
✓ Clean all nylon parts with detergents (do not use acid)
✓ wax bath thermostats should be set at least 3oC above the melting point of the wax
✓ check the timing when loading the machine
