ABSTRACT:
In a process for preparing tissue for microscopic examination which process includes the steps of fixing a specimen of tissue, dehydrating the fixed specimen, clearing the dehydrated specimen, and impregnating the cleared specimen with paraffin, ultrasonic energy is applied to the specimen in each of the processing steps to reduce the total preparation time. Also, the time required to stain a specimen of tissue is reduced when ultrasonic energy is applied to the specimen while immersed in the stain.
