The Thai Journal of Veterinary Medicine

Forced impregnation process is normally performed under vacuum at freezing temperature which requires expensive plastination apparatus. To reduce the cost in the plastination process, forced impregnation of porcine hearts under two different environments, which are at the freezing temperature (-20oC) and at room temperature (22-25oC), was compared. Twelve porcine hearts were collected from a slaughter house, and divided into the groups, six in each, and subjected to be plastinated by S10 standard technique at the two temperatures. Although the forced impregnation at room temperature, also the curing process, was more time-consuming, all hearts from both groups produced satisfying plastinated specimens. …
