Cow eye dissection is popular because of the similarity to the human eye. See the cornea, iris, pupil, connecting muscles and veins, and other features. This is a plain preserved specimen of an adult cow eye.
Dissection specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced with water and then with a glycol solution to produce a moist, low-fume specimen which can be stored almost indefinitely. We recommend that you use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration over time is normal and does not indicate decay.
Store your specimens at normal room temperature--refrigeration is not
required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, specimens can be resealed in a Zip-lock bag to prevent them from drying out for later use. Ages 10 & up.

I ordered the cow eye for a dissection project for my home schooled children. The item came fast and in good condition. Our family learned a lot about the eye.

We ordered these cow eyes to do a demonstration for the workers at our supply plants of the importance of safety glasses. The demonstration really made an impact! The product arrived in great shape. I would have preferred clearer directions about storage, but other than that I have nothing to suggest for improvements. Thank you Home Science Tools!

Ordered a large number of eyes and they came in quickly, well preserved. A few had been squished in transit, but not so badly that they could not be used. Students were able to uncover the optic nerve as it exited the eye and the retinas stayed intact longer than previous orders. Great experience for my students!

My students thoroughly enjoyed dissecting these cow eyes. We are looking forward to dissecting the other specimens we have purchased.

This was a great lab. I ordered it for my Home School Science class and they were awesome. The kids enjoyed comparing them to the human eye. The lens is really cool. Read More Reviews
