Application of histology paraffin wax

Paraffin wax is a hydrocarbon produced by the splitting of mineral oils. Its properties are very different. The melting point is in the range of 45°C to 75°C. Paraffin wax with a low melting point is milky white to the naked eye and brittle to the touch. Paraffin wax with a high melting point, the meat is light yellow when viewed from the meat, and it is soft to hard to the touch, and not easy to break.

The best form of paraffin wax is emulsifying wax. Emulsifying wax has the characteristics of acid and alkali resistance, strong water solubility, emulsion stability, long shelf life, high solid content and good dispersibility. It can be used in grinding, papermaking, leather, wood, agriculture, explosives, Industries and fields such as medicine, ceramics, cosmetics and automobile protection.

Histology paraffin is an important embedding agent used in animal and plant tissue sectioning technology, and is a basic material for biology, medicine, pathology and immunohistochemistry. At present, there are many kinds of slicing paraffin used in China. High-melting paraffin is hard, difficult to slice, and its softness is not suitable, but thinner slices can be cut; low-melting paraffin has low hardness and insufficient support for slices, making it difficult to cut flakes. Therefore, in order to improve the quality of medical paraffin in my country and improve its competitiveness in the market, the development and research of medical paraffin is becoming more and more important.

Due to the wide range of paraffin melting points, there are many choices, so it is necessary to choose the paraffin wax suitable for the use of the unit in the region. In order to produce high-level and high-quality pathological tissue sections and various tissue sections, if the selected paraffin has a high melting point and the hardness of the paraffin is hard, the sections are difficult to cut and the softness is not suitable. If paraffin with a lower melting point is selected, the hardness will be reduced, the support force of the slice is not enough, and it is difficult to cut thin slices.

Advantages of  Histology Waxes granules TWAX-88 series:

1. Practical granular paraffin, suitable for dipping, embedding and sectioning of tissue samples.

2. High-quality paraffin and standard polymers are compounded by advanced technology.

3. The slicing is smooth, and the thinnest thickness can be as low as 2 μm.

4. The melting point ranges from 52℃ to 62℃, you can choose freely according to your needs.
