Molecular model construction kit, organic, demo

This molecular model construction kit for demonstration is appropriate to the chemistry classes organics. The kit contains all needed elements and connections for ball-and-stick and semi space filling models of acyclic and cyclic standard molecules. It is suitable for demonstration of different conformations and stereo isomers. 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.
