Our Foundation student organic chemistry model set is priced for single course needs but don't throw it away when you are done. You'll have enough atoms & unused bonds to make a stand that turns your cellphone into a bedside clock.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for 30+ years. These parts are compatible with every molecular model set we have sold since day 1. This quality may appear expensive but no parts support from other vendors costs even more.
Need a student set that builds larger structures stuff that a chemistry or biochemistry major might want? The 68827W, Advanced Organic Chemistry Student Model Set has 24 carbons, 36 hydrogens & more. Plus, it comes with our indestructible clear vinyl "wobbly"™ bonds that we use in all our Orbit molecular model kits & 68847W class chemistry set (200 carbons, 200 hydrogens).
I've had consistently great service from this company. Our students seem to really appreciate the reasonable price. In the years that we've used this product, not one has been returned due to defects.
Considering how many of these we sell to schools every year, that is high praise indeed. Thanks letting us know.
