Unit Class Demonstration Set

The Unit Large Molecular set is a multi-purpose design intended primarily for showing organic molecules and VSEPR theory in a large lecture hall setting. It can be used for to alkanes-alkenes-alkynes, aromatics, enantiomers and more. The main Unit atoms are 45mm in diameter.

The new, reconfigured version, 69175, will be available end of April, 2010.
