ormalin is a solution of formaldehyde gas dissolved in water, typically containing about 37% formaldehyde by weight. It is widely used as a disinfectant, preservative, and in the preparation of biological specimens for study.
Key Uses of Formalin:
- Preservation: Formalin is commonly used to preserve biological specimens, such as tissues and organs, for scientific research or educational purposes. It prevents decomposition by killing bacteria and fungi.
- Disinfection: Due to its antimicrobial properties, formalin is used to sterilize medical equipment, rooms, and surfaces, especially in hospital settings.
- Tissue Fixative: In histology and pathology, formalin is used to fix tissue samples before microscopic examination. It helps preserve the tissue structure for accurate analysis.
- Mummification: In some cases, formalin is used for mummifying animals or human remains.
