Whenever you use preserved specimens in the classroom you have a right to understand the chemicals and preservation process of the company you purchased your materials from. In this video, you will learn how Nasco Education preserves its premium-quality dissection specimens with NASCOGuard®.
NASCOGuard® is a non-toxic, 99.7% formaldehyde-free humectant fluid made up of propylene glycol and water. As a fixative solution, NASCOGuard® fixes to the specimen tissue on a molecular level which prevents your specimen from decay, bacterial growth, or contamination.
