The 2 hole, 23mm diameter, 105 degree Molymod atom is used to represent metals and is included in 3 of our teacher's sets; the 62003, 62004 & 62034.
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.
