DRX-3 - Complete selection of pharmacy scales and balances


The DRX-3 Torsion Balance defines prescription weighing principals in a Pharmacy. Built with the classic Torsion mechanism, the TORBAL DRX-3 pharmacy balance has sensitivity of 2mg, it is independent of wear, unaffected by dust or dirt, and adjustment is permanent – all of which adds up to extra-long, useful, maintenance-free service.

Functions and Features

The Torbal Model DRX-3 meets or exceeds all the specifications and tolerances for a Class III prescription balance as defined in NBS Handbook 44, DRX-3.

Torsiona Bands

  • A cobalt, chromium, nickel alloy with constant torsional properties over a wide temperature range. This alloy also offers extra strength and corrosion resistance

Deep Plexiglass Lid

  • Extra height permits weighing with the lid down. Plexiglass offers strength with good visibility of pan and index.

Stainless Steel Pans

  • Highly polished and corrosion resistant.

Sealed Case

  • One piece metal case has overlapping plate glass top. Complete protection against dust and chemical seepage.

Leveling Screws

  • Non-binding; under the case, so chemicals cannot drop into the threads and cause corrosion.

Magnetic Damping

  • Speeds up weighing by eliminating unnecessary swings of the pointer.

Spirit Level

  • Insures level of balance from front to rear.
