Beam Scale stets the standard for the balance beam scale category. The renaissance of a classic calls for more than just a tool for weighing. Beam Scale represents 160 years of manufacturing experience, as well as the courage to set new standards which Beam Scale's capacity to 400 lb. A slip resistent, heavy duty, cast iron base, eliminating the need for a mat, is just one feature that's typical of beam scale ease of use. By merging the classic body design and white color with innovative features, has created a superior product that offers long life Beam Scale is available with lbs, kg, or lbs/kg display. The Beam Scale has a cast-iron base and case-hardened pivots and this means Zero deflection. Every scale is checked for accuracy before shipping. The thick nickle/chrome beam and die-cast beam caps only add to the true value of this balance beam scale. There is no plastic here. If you are looking to purchase the best balance beam scale possible, you will be proud of this purchase. Beam Scale can not be beat anywhere.

HISTORY Balances in the form of equal arm beam scales havebeen used from as early as 4000 BC. The accuracy ofthe basic idea of a stick with pans at each end across apivot was limited until the introduction, during the 16thcentury, of friction reducing metal knife-edge pivots at thecentre and beam ends. Until the mid 19th century, pharmacists used hand scales in the preparation and selling of medicines. More accurate and more convenientpillar-mounted bench scales replaced these.Man's first weights were stones (the name still exists as a weight on the older personal weighing machine - 1stone = 14 pounds).

Original Mediterranean weights werebased on the seeds of the liquorice plant and the carobplant and stone weights graduated to these. In ancient Greece lead was used.English weights were evolved by the Romans ( ounce =oncia, pound = Libra pondo) using a grain of wheat asthe standard. Apothecaries' weight, a variation of the Troy weight system, was used in Europe for themeasurement of pharmaceutical ingredients from asearly as 1270.

Henry VIII decreed Troy weights (5,760grains to a pound) to test coins. Elizabeth I decided thata pound of 7,000 grains should be used for selling ordinary goods and that Troy weights were to beused for precious metals and stones. In 1758 Parliament legalised only the Troy pound. However, traders preferred the 7,000-grainAvoirdupois pound which they continued to use. It was standardised in 1824. Despite formal adoption of the Avoirdupois weights and measures under the Medicinal Act of 1858,Troy weights remained in general use for prescribing and dispensing. The British Pharmacopoeiaof 1914 adopted the Metric system for all but medicinal doses. Dispensing continued in theApothecary system until 1 January 1971 when metric weights and measures were adopted. Measures of volume have been used for solids and liquids, although pharmaceutical use has beenmostly for liquids. Until the 17th century, measures were mainly manufactured from wood whichgave way to pewter, horn and, by the 19th century, to glass. The 1618 London Pharmacopoeia adopted the Roman gallon as its basic liquid measure andgives a table for the conversion of units of liquid capacity into Apothecary weight. The Imperial Gallon was defined as the volume occupied by 10 Imperial pounds of water and was confirmed asthe standard in 1824.BALANCES Pharmacists have normally used two sizes of balance weighing up to 2 ounces for small quantitiesand up to 2 pounds for larger quantities. In modern pharmacies digital electronic instruments havelargely superseded these balances.
