99.7% formaldehyde-free
NASCO-Guard ® specimens are the industry standard for high-quality, low-cost, low-odor dissection specimens. Dissection
labs become a positive experience for all students when NASCO-Guard ® odorless, nontoxic specimens are used.
Formaldehyde-free specimens sold by other companies use various combinations of chemicals that increase odor levels and
cost; reduce shelf life; and can make the dissection experience unpleasant for you, your students, and your budget. When
requesting a Material Safety Data Sheet for formaldehyde-free specimens, do not accept the term “proprietary mixture.”
Demand to know the chemicals you are being exposed to.
NASCO-Guard ® specimens allow students to work unhampered by the odor and messiness associated with formaldehyde,
and special ventilation is not required.

Advantage
Safe to use and dispose of
All specimens unconditionally guaranteed
Low pricing includes shipping containers
• Shelf life is guaranteed indefinitely when stored in originally sealed packaging
NASCO-Guard ® specimens are collected, processed, and packaged by skilled technicians. In our Wisconsin facility, we are
licensed and/or governed by the U.S. Fish and Wildlife Service, the United States and Wisconsin Departments of Agriculture,
and the Wisconsin Department of Natural Resources. We follow all guidelines for euthanasia as listed in the Report of the
American Veterinary Medical Association Panel on Euthanasia:
www.avma.org. Worldwide collections are also monitored by the Convention on International Trade in Endangered Species
(CITES): international.fws.gov/cites/cites.html. NASCO-Guard ® specimens are the best and safest money can buy. In the
NASCO-Guard ® process, skilled Nasco technicians remove the formaldehyde fixative in a series of water baths, and then
painstakingly perfuse the specimens with propylene glycol until tissue fluids contain at least 20% to 25% propylene glycol,
from 0.00% to 0.25% formaldehyde, with the remainder water. A minimum of seven chemical tests are performed during
this process to assure quality. NASCO-Guard ® specimens are biodegradable and suited for burial in an approved sanitary
landfill or for incineration. Ambient fluids may be safely disposed of via city sewers.
