What liquid is used for wet specimens?

Some specimens may not be fixed before being submersed in the fluid preserve. The fluid preserve: The preserve is commonly alcohol, either ethanol or isopropyl alcohol.

Do wet specimens last forever?

What do you put in a wet specimen?

When you have sufficiently injected your specimen, place it into a jar of formalin so it is submerged, and seal the lid.
