Paraffin sections
Enterprise Standard QDG1-2007
Histological paraffin section is a conventional production technology, the most widely used method. It is not only used to observe the morphological structure of normal cells and tissues, but also other disciplines of pathology and forensic medicine for research, observation and to determine tissue morphology of the main method. Now widely used in many other fields of study.
Chinese memorial tablets that contain some of the rules paraffin sections of the plasticity of polymer molecules of high-purity paraffin wax and add a small amount of dimethyl sulfoxide, so that rapid penetration of biological tissue, in the slicing process to minimize the contraction of the organization to address the fragile and difficult to cut, residue of the difficulty. This product is soluble in benzene, ether, chloroform, oils and carbon disulfide, insoluble in water and ethanol, it is non-toxic tasteless, particularly good toughness can be cut out of a continuous strip of high quality paraffin wax with a slice.
Chinese memorial tablets paraffin sections divided into two shapes:
One paraffin block slices, white solid blocks, there are creamy feeling, without any impurities. A clear and transparent when molten.
2, granular paraffin sections, particle full, even, translucent crystal, texture white non-miscellaneous debris. As the particles is small, easy to dissolve, shorter working hours, improve working efficiency.
China Paraffin sections memorial tablets specifications are:
Melting points: 50 ~ 52 ℃, 52 ~ 54 ℃, 54 ~ 56 ℃, 56 ~ 58 ℃, 58 ~ 60 ℃, 60 ~ 62 ℃, 62 ~ 64 ℃
Block: 0.5 kg / box, 20 boxes / case. Granular: 0.5 kg / bag, 20 bags / box.
