Colorless, most widely dispersed of the Serratia species. 

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Grass frogs are low maintenance and seasonally available, typically from September to July.

Students view the outer, middle, and inner ear with one model.

Individual spherical glass lenses.

High-Quality, Half-Sized Model At An Economical Price

Superior realism, reliability, and durability.

Fetal pig tissue showing early tooth development.

This totally new life-size (68") male/female model facilitates an understanding of human anatomy like no other human anatomy model in the world! The human that can be dissected, features a human torso that has the skin removed from one half showing the underlying musculature of the chest, back, abdomen, head and neck. The front wall of the torso detaches to reveal the inner structures and organs in tremendous detail. In all, 41 component parts can be dissected from the human anatomy model. The human anatomy model comes with wooden roller base.

Also Called a Synizetic Knot

Innovative Features Designed Especially for Science Education.

This organism is easily recognized by its trumpet-shape, and can commonly be found in freshwater ponds and streams. It reproduces by budding.
