Dorothy Hodgkin's model of pig insulin, c 1967.

Model of pig insulin's molecular structure.

 
Hofmann's apparatus, 1860s.

A W Hofmann's apparatus to demonstrate that the volumes of oxygen that enter into the composition of carbon and sulphur dioxide are equal to the respective volumes of these compound gases. (U tube with deflagrating spoon on stand)

 
Short-beam analytical balance, 1876.

Balance, made by Florenz Sartorius, can distinguish weights between samples that differ by as little as one part in a million. Sartorius founded his balance-making business in 1870 in Germany.

 
Soleil Scheibler polarimeter, 1887.

Soleil Scheibler polarimeter, 2 tubes for solutions, with box, made by Schmidt and Haensch.

 
Three viscometers, 1885-1911.

Experimental viscometer, formerly property of the late Sir Boverton Redwood in use, c. 1885, in glazed case

 
Dalton's wooden atomic models, c early 19th century.

Three wooden spheres used by Dalton to demonstrate his atomic theory.

 
Schmidt and Haensch polarimeter, c 1900.

Polarimeter by Franz Schmidt and Haensch, Berlin S., with stand, in box, serial no. 4838, D. R. pat. 82523, c. 1900

 
A pioneering ball and stick atomic model set, 1860s.

Atomic model construction kit (glyptic" type) consisting of a wood box containing variously coloured balls and two types of connectors; (a) U-shaped gilded metal (b) metal pegs and rubber tubes"

 
Kendrew's original model of the myoglobin molecule, 1957.

The original model of the myoglobin molecule, (the first ever to be made of protein molecule) constructed in plasticine in 1957 by Dr. J.C. (later Sir John) Kendrew; the contorted cylindrical shape, showing the track of polypeptide chain, is supporte

 
Space-filling atomic models, c 1955.

Selection of Courtaulds space-filling atomic models made of wood developed at Courtaulds Maidenhead Laboratory. Brass connecting links and rubber collars are included, together with a rule for measuring distances in Angstroms c. 1955.
