Paraformaldehyde is one of the most commonly used fixatives in immunohistochemistry (IHC) and immunocytochemistry (ICC) studies.The fixed agent is mild, and can preserve the antigenicity and fine structure of tissues well. It is suitable for the long-term preservation of tissue specimens and cell slices, and is very suitable for the photoscopic immunochemical study of tissues and cells.

Process index of paraformaldehyde:

The vacuum degree of concentrated washing tank is not less than 0.094MPa.4, the vacuum degree of dry washing tank is not less than 0.090MPa.5, the scraper evaporation pressure is less than or equal to 0.35MPa.6, the dryer jacket steam pressure is less than or equal to 0.5MPa.7. The water pressure of each condenser is greater than 0.2MPa.8. The outlet pressure of the liquid pump on the washing tower is greater than or equal to 0.3MPa.9, the steam pressure of the outer network is greater than or equal to 0.5MPa
