• Specimens can be used comfortably over extended periods of time

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 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.
