This article was originally published in Electrochemical and Metallurgical Industry Publication of February 1907. Information within this article is therefore correct as of 1907. The publication of this material aims to provide historical insight on the subject and its place in industry.

The adjoining illustration shows a new quick-acting, short-beam and highly sensitive analytical balance for scientific use, just placed on the market by Voland & Sons, of New Rochelle, NY. It embodies all the latest improvements which have been introduced by this firm in their twenty years of experience in the design of analytical balances.

The balance is mounted in a French polished mahogany glass case with front counterpoised sliding-frame and glass top. In the illustration the front and rear frames are removed to permit a better view. The case is 21 inches long, 20 inches high and 10 inches wide.

The beam of the balance is 8 1/2 inches long and is divided into 100 parts on either side. The beam is of truss construction and is made of hard metal of the manufacturers' own composition. The rider has a clean sweep over the beam and can be used from the zero point. The knife edges are made either of agate or steel. All bearings are of agate.

The pans measure 4 inches in diameter and the balance is sensitive to 0.1 milligram, with its full capacity of 500 grams in each pan, and it may be said that this rating is quite conservative.
