Weight Watchers of the World: Here's a complete line of lab balances. They give you everything except knife-edge problems. The Torsion Balance Company makes the most complete line of laboratory balances available. There is a laboratory balance for virtually any need and you can make your selection from a broad price range. So why not save yourself time and expense when you select a balance by making Torsion your first source? All Torsion balances have the same rugged torsion-band construction in common and hence are far more resistant to extremes of service than knife-edge balances. The Torsion balance construction has fulcra which twist instead of roll. There is no knife-edge fulcrum and no metal-to-metal wear. There are no bearings to accumulate dust or dirt in a Torsion balance. Thus the weighing mechanism is not affected by corrosive products or abrasive dusts in the atmosphere. Because of these construction advantages, Torsion balances are virtually maintenancefree. Their design includes a chemical resistant metal case, and silicone fluid damping or magnetic damping for fast weighing, The balances here are only a few of those designed to fit your needs. Write today for literature describing these balances. Then ask for a demonstration of t h e b a l a n c e meeting your requirements.

The Torbal EA-1-the most advanced analytical balance. • Capacity: 160 grams • Precision: 0.03 mg • Complete digital readout to 0.1 mg without vernier • Electronic null indicator replaces conventional optical system • Inaccuracies in weighing due to variations in deflection sensitivity are completely eliminated CIRCLE NUMBER 65

The Torbal PL-12 balance has • Capacity: 2000 grams • Precision: ± 0.05 g • Readability: 0.1 g The Torbal PL400D balance has • Capacity: 400 grams • Precision: ± 0.007 g • Readability: 0.01 g • High quality optics provide sharp image and high degree of illumination • No need to readjust zero point after balance has been moved • Tare up to full capacity CIRCLE NUMBER 66

The DWIYI 3V is a Torbal top-loader that makes weighing five times faster than graduated beam balances. • Capacity: 200 g • Weight control dial and fine weighing dial with vernier give direct readings from 100 grams to 0.01 grams • Magnetic damping • Stainless steel pans CIRCLE NUMBER 67

The Torbal DH-2 (a) is a high capacity balance that has a notched beam graduated to 100 grams in 10-gram increments, plus a dial graduated to 10 grams in 1/10 gram increments. DH-2(b)—same as above with ungraduated tare beam instead of notched beam. • Capacity: 2000 g • Sensitivity: 0.07 g DH-4(a)—similar to above, except 4V; Kg. capacity. CIRCLE NUMBER 67 The Torbal ET-1 Is the only top-loading balance that gives 1 mg accuracy, complete digital display without optics or verniers. Electronic null readout minimizes errors. • Capacity: 160 grams • 40 additional grams of tare available • Glass door hood enclosure to protect against air currents CIRCLE NUMBER 08

The Torbal DWM5 is a high capacity balance that combines speed of weighing with accuracy and ruggedness.

fast, accurate top-loader for "semi-analytical" weighing. • Capacity: 120 grams • Readability: 2 mg • Dial reading: 10 grams to 0.01 g • Magnetic damping CIRCLE NUMBER 67
