ES Models

MOLECULAR MODELS, "ORBIT" SYSTEM

For research and teaching. The system uses atom centres moulded in 15 different
shapes each with a reference letter a to q. Centres are colour coded according to
the element. There is a total of 12 colours and 54 colour/shape combinations. The
system includes multiple bond pegs, w, x and y, designed to prevent rotation of
double bonds. Atom centres are joined by plastic tubes which are supplied cut to
lengths suitable for building models on a scale 3cm = 100ppm.

assemblies (thymine-adenine and cytosine-guanine base pairs, sugar rings and
phosphate groups) which are joined together to make an impressive display and
teaching resource.
12 base pairs show more than one turn of the double helix and the major and minor
grooves of the protein lysozyme. The finished model is 85cm high and 40cm wide
and can be set on a suitable stand (C50-7610) or suspended from a hook.
Contents: 750 atoms, 850 bonding straws, a set of wooden plates for hanging the
model plus assembly instructions and a worksheet examining the structure of DNA
and process of transcription.
