Formaldehyde solution
In stock
Formalin (a 37% aqueous solution of formaldehyde gas) is a potent biocide and tissue fixative used in veterinary medicine. It is prized for its broad-spectrum antimicrobial efficacy, antifungal properties, and ability to halt enzymatic breakdown, though its pungent, toxic vapors mandate strict handling protocols.

Specs & features.
Formaldehyde is a simple organic compound that is a colorless, flammable gas at room temperature with a distinct, pungent odor. As a volatile organic compound (VOC), it is widely used in manufacturing resins, building materials, and as a preservative, but is classified as a known human carcinogen.
No specifications have been listed.
- Microbial Deactivation: It kills bacteria (including Salmonella), viruses, and fungi by alkylating the amino and sulfhydryl groups in cellular proteins, effectively destroying the pathogen.
- Tissue Fixation: It cross-links proteins in tissue specimens and cadavers, halting decay and preserving cellular structure for histopathological examination.
- Chemical Stability: Full-strength commercial formalin is stabilized with 6-12% methanol to prevent the reactive formaldehyde gas from polymerizing into solid paraformaldehyde.
