Catalog type History
Provenance Found by Dr. Bowman at Surplus in 1984. Note (in file) says "Needs new lamp, 25 w frosted tubular 1 1/4 dia 4" long frosted bulb linear fil (?). Needs prism sample holder. Fisher Cat. $400 for above or below RI o/glds. 0 to 80% sucruse range. +/-.002." The refractometer was used to determine sugar concentrations and total solids in preserves, etc. An illuminated scale and tiny sample holder which meant that less sample was needed made the instrument unique.
