Tetrahedral sp3 carbon atoms are in every Molymod molecular model organic set & kit. Use our 3D Molecular Model Builder to build almost any one of the more than 50 million compounds in the NIH database (not all tested). We've been selling them since 1994. They're so precisely made, they're compatible with those sold before or since.

The uniqueness of carbon comes from the fact that it can bond to itself in many different ways; in straight chains, branched chains and rings. It can also bond singly, doubly and triply to itself. The chemical basis of all living organisms is linked to the way that carbon bonds with itself and other atoms1. Not so with silicon2.



1) Organic compounds.
2) Silicon-Zeolites, Computer Chips & Clays but Alien Lifeforms?

Why Does Precision Matter?

Every Molymod atom has holes 5mm +/0.1mm so every Molymod bond can connect them. This matters to teachers for obvious reasons. It matters to us since we use equally precise 5x5mm Nd magnets in our AtoMag™ magnetic molecular models such as cyclohexane, glucose or functional group.

Making ethanol models as gifts. Who knew ethanol looks like a dog? Also it's a great product, everything went together well.

Better to hand out models of ethanol than "hair of the dog" hangover cures! Thanks for letting us know.


No way could I make a ball with four evenly-spaced (tetrahedral) branches, but Indigo had them for me at a reasonable price. I needed a bunch of them, too. They came in a matter of days and meet my needs perfectly for illustrating a carbon atom. I just wish they had given the holes dimension, so I would have known exactly how they would connect with other pieces ahead of time (which BTW, are 3/16 inch diameter).

— Don
— Indigo:

Actually, the holes are 5mm & you can press our 5x5mm Nd disc magnets into them. We were able to make some interesting magnetic models this way. What we think is the best cyclohexane chair-boat, chirality demonstration & so on.
