Preserved Specimen: Grass Frog

Teachers will appreciate the Anatomy Lab’s Preserved Grass Frog Specimen because it is the perfect specimen for observation, study, and dissection. This amphibian offers a complex internal anatomy, containing major organ systems that are valuable to students studying biology, anatomy, or physiology.

The grass frog dissection specimen provides an enhanced hands-on learning experience in understanding comparative anatomy and amphibian anatomy, including organs, systems, and structures. Learning the anatomy of this specimen gives great insight to the effects of ecology and evolution on different vertebrates

Injection Type: 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.

Shipping Notice:

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.

Caring for Your Specimen

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

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

Storing 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 stored out of direct sunlight and kept 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 its life. Typically, our specimens should last a couple of weeks when properly cared for.
