Demo molecular model kit, inorganic & organic chemistry

This molecular model construction kit for demonstration is appropriate to the chemistry classes for inorganics and organics. The kit contains all needed elements and connections for ball-and-stick- models of organic and inorganic standard molecules. The models are easy to assemble and disassemble. They are characterised by high quality and durability. The kit is delivered in a plastic case, which enables a clear and comfortable storage. Every part is extreme robust and colored according to international standards. The diameters of the balls are approx. 17 mm for hydrogen and approx. 23 mm for carbon and most of the other elements.
