Balances

Balances are laboratory instruments that measure the mass of a sample, from gram-scale amounts down to the microgram and below, by balancing the unknown weight against a known reference force. On Questpair, 4489 balances are listed across new, used and refurbished condition, from 22 verified suppliers and distributors. Of those, 60 percent of the listings are used, the rest new. A laboratory balance sits at the base of gravimetric analysis: reagent preparation, sample dosing and quality control all begin with an accurate mass reading. Readability, the smallest mass change the instrument resolves, separates one class from the next, and that figure decides which balance a given task needs.
