Tissue-Tek O.C.T. Compound


Tissue-Tek O.C.T. Compound is used to quickly embed fresh tissue specimens for frozen sections using a cryostat. Tissue-Tek O.C.T. Compound is a formulation of clear, water-soluble glycols and resins, providing a solid matrix to encapsulate tissue specimens and bond to the Specimen Holder for consistent sectioning in a cryostat working temperature of -10°C and below.
