The rat provides insights into different systems in the body as it has fully mature reproductive and circulatory systems. This specimen is also a great alternative to fetal pig specimens due to its economical cost.

Learn about comparative anatomy with this dissection specimen by studying the similarities and differences of its internal and external structures against other mammals’, including humans. This dissection specimen is great for understanding the physiology, functions, and systems of the mammalian body.

This 7 - 9” preserved specimen is great for students studying biology, microbiology, anatomy, and zoology as it provides a detailed view of the organ and organ systems that exist also exist in human bodies. Choose between two injection types to fully enhance your hands-on learning experience.

Injection Types:

Plain Injected

Plain injected specimens have not been injected with colored latex so the arterial, venous, and hepatic systems are presented in their natural colors.

Double Injected

Double injected specimens have been injected with colored latex, resulting in the arterial system appearing red and the venous system appearing blue.

Shipping Notice:

All specimens are packaged in vacuum-sealed, Mylar-coated, polyurethane bags. The vacuum pack keeps the specimen moist. Anatomy Warehouse recommends that you keep your specimen wet with holding fluid every time you use the specimen. A pail or jar for your specimen will ensure the longevity and usability of your specimen.

Some specimens may have a lead time of 4 - 6 weeks before your item is ready to ship. Please send us a message via Live Chat or give us a call at 800-422-1134 for more information.

Preservation Process:

Formalin is the most widely used, economical, and effective fixative used in preservation. Our supplier utilizes a low concentration (3.7%) to effectively preserve the entire specimen and prevent decay. After fixation, specimens go through a series of washes to remove residual formalin. The amount of residual formalin remaining is usually less than 1%, which is in line with the federal OSHA standard for formaldehyde LTL exposure of 0.75 ppm over an 8-hour period. Specimens are then stored and packaged in the supplier's non-toxic, non-formaldehyde holding solution. This solution inhibits decay, fungal and bacterial growth, and prevents desiccation of specimen. Specimens are never shipped in formaldehyde.


This product can expose you to chemicals including formaldehyde, which is known to the State of California to cause cancer, and methanol, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to

Shelf Life and Storage

Take Care of Your Specimen

Specimens should be stored at room temperature and out of direct sunlight whether they are opened or unopened.

While dissecting your specimen, spraying the specimen with holding fluid will help keep the specimen moist, which will allow you to maximize your time with the specimen.

After dissection, spray your specimen generously with holding fluid before storing your specimen in an air-tight container. By following these guidelines, you can reduce the number of bacteria, mold, or other air particles on the specimen that will help inhibit mold growth.

Properly Store Your Specimen for Longevity

Unopened specimens are guaranteed to stay fresh for up to a year. With proper storage, this specimen can last for years if you store your specimen out of direct sunlight and keep it at room temperature.

Opened specimens are under no guarantee. Once a specimen is opened, it is up to you to care and store the specimen properly to extend the life of the specimen. Typically, our specimens should last a couple of weeks when properly cared for.
