infiltration Flashcards
simplest, most common and best embedding medium used for routine tissue processing
paraffin wax
done under a negative atmospheric pressure inside and embedding oven
vaccum impregnation
melting point of paraffin
65 C
paraffine wax substitutes
paraplast, ester wax, and carbowax
highly purified paraffin and synthetic plastic polymers
paraplas
paraffin substitute that can be used for impregnation without the need for alcohol removal
ester wax
photosensitive solution for impregnation made up of equal parts ether and alcohol
celloidin
celloidin impregnation method preferred for processing whole eye sections
dry method
celloidin impregnation which uses Gilson’s mixture instead of 70% alcohol
dry method
Gilson’s mixture composition
choloroform and oil of cedarwood
celloidin impregnation primarily used for bones, teeth, large brain sections and whole organs
wet method
embedding medium that provides superior results for light microscopic studies
resin
classifications of embedding plastics
epoxy, polyester, acrylic
epoxy plastic that infiltrates the fastest
cyclohexene dioxide
embedding plastic used for electron microscopy in the mid-1950s
polyester
