Student molecular model construction kit, stereochemistry

This molecular model construction kit for students 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 three plastic cases, which enables a clear and comfortable storage. Every part is extreme robust and colored according to international standards.
