Wet collections are natural history specimens immersed in liquid preservative solutions and typically stored or displayed in glass or plastic containers. The preservative solutions are predominantly ethanol, formalin or isopropanol.

The primary purpose of wet collections is for scientific research. In some instances, wet collections may be of species that are rare or extinct. These collections are not only irreplaceable, but they are also inherently hazardous to store and handle without proper precautions.
