Unit demonstration models for biochemistry

Build large-scale models the whole class can see! Perfect for front-of-class demonstrations and lectures.

Unit demonstration models for biochemistry
 
The Unit molecular modelling system features large (44mm diameter) spheres in seven colours to represent different atoms plus a 25mm diameter white hydrogen atom. By inserting radial, polar and tetrahedral pegs into the spheres you can make any bond angle which can then be joined with either rigid aluminium or flexible vinyl bonds.

New to the system are electron orbitals to show VSEPR theory and to represent lone pairs.

Packs of individual atoms, pegs and bonds are available to order for making custom models for studying biochemistry.
