Molecular model construction set, extension set inorganic/organic chemistry, demo, ball sizes 30/40/50 mm

Function and Applications

Demo molecular model construction set as an extension set to the basic demo molecular model construction set (item number 39829-01). For building inorganic and organic molecule models. With large spheres of 30 (hydrogen), 40 (e.g. carbon) and 50 mm diameter (e.g. sulphur). Ideal for front-of-class teaching.

Benefits

• For inorganic and organic molecular models

• Large sphere diameters

• Equipped with all necessary elements and connectors

• Optimally suited for both beginning and advanced chemistry classes in high school

• Supplied in a transparent plastic box, which allows for clear and convenient storage

• All parts are extremely stable and colored in the international standard color
