The tetrahedral sp3 nitrogen atom is supplied with most of our student and teacher model sets but can be bought separately to augment any set or kit.
Indigo Instruments has maintained a substantial inventory of genuine Molymod atoms & bonds for over 30 years. These parts are compatible with every set & kit we have sold since day 1. Though quality may appear expensive, no parts support from other vendors costs even more.
Use only these genuine Molymod Atoms & Bonds for full compatibility with any of our Molymod Molecular Model Sets & Molymod Molecular Model Kits.
