Carolina's Perfect Solution® - Safe, Convenient, Superior. You and your students deserve the very best quality and safest preserved specimens available. With that objective in mind, Carolina Biological scientists and technicians developed a preservation formula that produces superior specimens while it also improves the safety of your classroom or lab. Organisms preserved with Carolina's Perfect Solution® retain more lifelike color and texture. Because students study more natural-looking specimens, it's easier for them to identify the structures and, as a result, learn anatomy.

For a class of 30. Students study the anatomy of a crustacean, the most widespread group of aquatic arthropods.

Kit includes 30 Carolina's Perfect Solution® single-injected (circulatory system) crayfish, 30 self-locking storage bags, and a teacher’s manual with blackline masters for reproducible student guides.
