Cornelsen Experimenta 42880 Classroom kit

10 x Models for chemical molecules 2

This class kit is useful as an extension of the molecular construction kit 1. By combining the two boxes, your students can build up a variety of organic chemistry compounds in the classroom. The Benzolring models can be used to illustrate even aromatic hydrocarbons.

The spherical rod models clearly show the positions of the atomic nuclei and the bonds between the atoms. The molecular models are built by simply connecting the atomic models using the connectors. Even multiple connections can be shown with the flexible connection pieces.

The color marking of the atomic species corresponds to international agreements.
