Eisco Labs Giant Molecular Model Set – 343 Piece Chemistry Kit with Large Atoms & Bonds for Classroom Demonstrations

The Eisco Labs Giant Molecular Model Set (343 pieces) is the ultimate teaching tool for visualizing molecular structures on a large scale. Designed for classrooms, lecture halls, and group demonstrations, this oversized model kit allows every student to clearly see atomic connections, bond formations, and molecular geometry.

Each atom is 1–2 inches in diameter, making it easy to handle and perfect for teaching organic, inorganic, and biochemistry concepts. The kit includes 99 durable, color-coded atom models representing hydrogen, carbon, nitrogen, oxygen, chlorine, fluorine, and bromine. Atoms feature multiple “faces” to indicate bonding sites, allowing accurate construction of simple and complex molecules.

The set also comes with an assortment of bonds and connectors—including single, double, and flexible turning bonds—along with a removal tool for easy disassembly. Molded from tough, long-lasting plastic, this molecular model kit is built to withstand years of classroom use. A sturdy hard storage case keeps all 343 pieces organized and secure, ensuring easy transport and storage.

Ideal for teachers, professors, and students, this kit makes molecular chemistry hands-on, interactive, and visually engaging.
