If at all possible, formalin should be used for injecting and fixing specimen. It is also used in the manufacture of antiseptics. Formaldehyde is a colorless, odorless and tasteless liquid that has been used since the early 1900s as a preservative in foodstuffs, cosmetics, and pharmaceuticals.
States, it is commonly used to prevent spoilage in meat, poultry, fish, eggs, dairy products, fruits and vegetables, as well as in many other food products. (FDA) has approved the use of Formaldehyde for the prevention and treatment of foodborne illness in humans and animals.
FDA does not regulate the chemical’s use for injection or fixation of specimens, nor does it regulate its use in other medical procedures, such as dentistry, orthodontics, ophthalmology, dermatology, urology, or otorhinolaryngology.

How do you preserve a snake without formaldehyde?
We use a solution of at least 70% alcohol to water that can be purchased from any drug store.

Mix the alcohol and water in a small saucepan and bring to a boil over medium-high heat.
Once boiling, turn off the heat and let the mixture cool to room temperature. If you have a thermometer, you can use it to measure the time it takes to cool down, but it’s not necessary to do so as long as you keep an eye on it and don’t let it get too cold or too hot.

The researchers found that the oldest specimen was preserved in a mixture of ethyl alcohol and ethanol, while the other specimens were preserved either in ethanol alone or in an ethanol-only solution. The researchers that this suggests that ethanol was used as a preservative to preserve the specimens.
However, the researchers note that they cannot rule out the possibility that other substances were used in the preservation process.
What liquid is used to preserve specimens?
