An excellent choice for any activity requiring dissection of a vertebrate animal! See organ PLUS the circulatory system with Cornerstone's double-injected grass frog. Each specimen is 3" - 4" long and injected with red latex to show the arterial system and blue latex to show the venous system.

Specimens are individually vacuum-sealed. Initially preserved in formaldehyde to fix tissues, specimens are then rinsed with water and packed in a low-odor, non-toxic holding solution.

Store specimens in an area of room temperature away from direct sunlight. Do not freeze or expose to high temperatures (more than 85ºF). Specimens will last up to 12 months when left unopened. After opening, the specimen should be placed in a zip-top bag and may be kept for up to one month.

*Available in single with a discount once you purchase 10 or more.
