Integrated Globes Apparatus (A -25)
The globes are brushed aluminum and the stand stainless steel . The globes’ dimensions are identical as is their internal configuration. The apparatus is designed to measure transparency of substances. A lever lowers the sprung lower globe to allow a thin specimen of the test substance to be placed over an aperture between the two globes and release of the lever fixes the specimen in position. On switching on the light a meter indicates how much light passes from one globe to the other which then gives a measure of transparency. American patents, otherwise only name is ‘Sud’ Probably c. 1960
We have not seen one of these before but nobody visits us without remarking on this striking apparatus. A wonderful show item
