General description

Histosec pastilles - solidification point 56-58 °C embedding agent for histology, is an embedding medium for histology of samples of human origin. it is a paraffin enriched with polymers and containing DMSO (dimethyl sulfoxide). Histosec pastilles (without DMSO) (Product number 1.15161) is also available. DMSO (dimethyl sulfoxide) increases the rate of penetration of paraffin and provides additional preservation of the tissue structures. Its melting range is between 56 - 58 °C and, within this range any specimen can be processed without fear of damage irrespective of the method used. In most clinical laboratories the paraffinization is performed with an automated embedding system and is performed directly after the histoprocessing. The Histosec pastilles are well soluble with the Intermedia Xylene (isometic mixture) (Cat .no. 108298) or xylene substitutes such as Neo-Clear(Product number 1.09843).The paraffin is an IVD registered product and CE certified, thus can be used for clinical diagnostic purposes. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
