A Modified Soxhlet Extractor for Histologics and Histochemical Use

If the standard Soxhlet continuous-extraction apparatus is modified by the addition of a water jacket around thextraction chamber, the temperature of tissue undergoing extraction can be kept safely below damaging limits. Subsequent routine processing and examination of tissues after the cool extraction showed that they were less friable and had fewer structural distortions than those extracted with the uncooled, standard type c apparatus.
