7000/ Advanced Set (HGS Stereochemistry Molecular Model)

Various types molecular models exist, but when dealing with the stereochemistry of organic molecules, no kit is better than the Maruzen 4000 or the expanded Maruzen 7000 stereochemistry sets (1 Ã… = 2 cm) for daily use by organic chemists and biochemists. For the use of individual students, there are the compact 4010 sets. The chair, boat, or envelope inversion of ring structures can be readily performed, strained rings can be constructed without difficulty, and projection angles of distal bonds can be measured directly. Such features become indispensable when engaged in such studies where conformational analysis is critical, such as NMR coupling constants or projection angles between distal bonds
