Injection Options for Preserved Specimens

We offer many of our preserved specimens with latex injections. During the preservation process, we inject color latex into the arterial system (arteries), venous system (veins), hepatic portal system (hepatic veins), and/or another system of tubules for better visibility. This makes injected specimens ideal for advanced study of the circulatory system.

Specimens are single, double, or triple injected—meaning 1, 2, or 3 of the above systems are injected, each with a distinct color. However, color and injected systems vary among specimens.
