medical use: Formaldehyde solutions are used as a fixative for microscopy and histology. Formaldehyde-based solutions are also used in embalming to disinfect and temporarily preserve human and animal remains. It is the ability of formaldehyde to fix the tissue that produces the tell-tale firmness of flesh in an embalmed body. In post mortem examinations a procedure known as the "sink test" involves placing the lungs of an animal in an aqueous solution of formaldehyde; if the lungs float it suggests the animal was probably breathing or able to breathe at the time of death.
biological use: An aqueous solution of formaldehyde can be useful as a disinfectant as it kills most bacteria and fungi (including their spores)

How does formalin attenuate bacterial virulence?
Formalin is a solution of formaldehyde, which is highly toxic. A third of an ounce of formaldehyde can kill an adult human. Formalin kills the bacteria, but leaves it intact enough to be used for vaccines.
What is the most commonly used fixative for routine histology?
neutral buffered formalin
What is the name of the aqueous solution of formaldehyde that is available commercially as tissue preservative?
Aqueous solutions of formaldehyde are referred to as formalin. "100%" formalin consists of a saturated solution of formaldehyde (this is about 40% by volume or 37% by mass) in water, with a small amount of stabilizer, usually methanol to limit oxidation and polymerization. A typical commercial grade formalin may contain 10-12% methanol in addition to metallic impurities like aluminum (3 ppm), iron (1 ppm) and copper (1 ppm).
Why you are using formalin?

Why is Formalin used for preserving biological specimens?
formalin is uesd for preserving biological specimens because formalin checks the bacterial growth and prevents the specimens from decaying. it also prevents the bad odour from these species.
What is composition of formalin?
Formalin is a saturated solution of formaldehyde, water, and typically another agent, most commonly methanol. In its typical form, formalin is 37% formaldehyde by weight (40% by volume), 6-13% methanol, and the rest water.
