To better serve the needs of all teaching environments and preferences, WARD’S® offers this line as an alternative to our existing line of high-quality, safe preserved specimens. Absolutely no formaldehyde and it is used in the fixing and preserving process for these specimens.
Instead, this solution used for preparation and binds with the tissue as non-toxic, cross-linked proteins, making the solution truly 100% formaldehyde-free. WARD’S® offers the largest selection of specimens prepared with this alternative process, including the widest range of sizes and injection styles.
