We offer a variety of used and reconditioned balances, including top loading, analytical, semi-micro, and platform balances. (We even have some old-school triple beam scales!) With prices that can save you up to 60% off the price of comparable new models, American Instrument Exchange offers a tremendous value on a diverse selection of lab scales.
But don’t mistake low cost for low quality: our technicians test each balance to insure repeatability, correct cornerload tolerances, linearity, and reduced span at or near full capacity. We also test all displays and controls as well as any other features and accessories, such as auto-calibration and draft shield retraction, to make sure every scale we ship is fully operational.
Types of Balances
Analytical balances are designed specifically for laboratory use and measure small masses in the sub-milligram range. Analytical balances provide accuracy to at least 0.1mg inside transparent enclosures called draft shields so that air currents do not impact the scale’s operation. Draft shields also ensure that dust and other debris can’t collect on the weighing pan when not in use.
Top loading scales are generally used for larger capacity applications than analytical balances, when precision of 0.1g is adequate. The versatility of top loading balances makes them among the most widely used types of scales in both industrial and lab settings.
Semi-micro and micro balances can often be found in product testing and QA labs as well as any setting in which small levels in weight variation is critical to result. Micro balances are capable of measuring with accuracy to within 0.00001g.
All of the equipment shown on our website is in stock and available. Orders ship from our 30,000 square foot warehouse in Haverhill, MA. Our surplus lab equipment is reconditioned for many types of laboratories, including biotech, biomedical, medical research, chemical, pharmaceutical, and university and hospital research laboratories. We have been a reliable source for used laboratory and scientific equipment since 1969.
