Every lab needs a great analytical balance to take accurate and reproducible measurements of reagent weight. Opting for the most dependable analytical balance entails assessment of the cost, durability, repeatability, and measurement range (or readability). Analytical balances characteristically measure in the range of micrograms to milligrams. An additional consideration to make is the size of the balance as it will need to be accommodated on the lab bench. The cost of analytical balances varies, but they are worth an investment as they normally have a long lifetime. https://www.ste-mart.com/category-analytical-balances-pre-owned-2862.htm
