Paraffin wax blended with synthetic polymers, Solidification point: 56-58°C, in pastille form, Histosec® embedding agent for histology, with DMSO, Sigma-Aldrich®
Supplier: MilliporeSigma
M-Clarity™ quality level = MQ400
Histosec® pastilles is an embedding medium for histology of samples of human origin. It is a paraffin enriched with polymers, also available without the addition of DMSO (dimethyl sulfoxide). DMSO 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.
- These paraffins are ready to use at a temperature of 60 °C.
In most clinical laboratories paraffinisation is performed with an automated embedding system and directly after histoprocessing.
Histosec® pastilles are soluble with Intermedia Xylene or xylene substitutes (such as Neo-Clear®).
The paraffin is an IVD registered product and CE certified, so can be used for clinical diagnostic purposes.
