Balance .
While still retaining the convenience of a tare beam, we have added to the widely used metric solution balance a graduated beam to enlarge the range of usefulness. Two models are available: one with a beam graduated up to 100 grams by one gram, and another 500 grams by 5 grams. In addition, brass weights from 1 gram to 2 kilos are included as well as two extra iron tare weights of 8 and 16 ounces. The balance is finished in brown baked enamel and has agate bearings. It is eguipped with two removable 9 inch diameter brass pans, and is of sturdy construction throughout. Capacity 5 Kilograms

SIMPLIFY MELTING POINT DETERMINATIONS There's no need to wire melting point capillaries to a ther mometer. Just insert them in the loops of our specially designed thermometer (U. S. Pat. No. 2,079,344). A flat disc sealed to the mercury bulb holds capillaries at the proper level. N o .
