These highly accurate weighing instruments are used for quality control of the processes involved in the pharmaceutical industry manufacturing production. Analytical balance can weigh small amount of samples with capacity of 82g at 0.01mg and up to 220g at an accuracy of 0.1 mg. it is very important to analytical chemistry because it could measure mass in sub-milligram range. Analytical balance can be used for measuring weights ranging from 0.1 mg to 200 g. The ability to measure such small intervals means that specific steps must be taken before taking the measurements. â¬ 1.904,40 â¬ 1.784,80. Most analytical balances are so accurate, even just minor breezes caused by someone walking by would disrupt the reading. Read and follow the operations manual. Analytical balances used in a pharmaceutical lab are used for extremely precise measurements, such as the microbalance capable of measuring 1 millionth of a gram, for instance. Sale by units.

A standard analytical balance typically has a maximum capacity of 160â300g and a readability of 0.1mg. To check the leveling on the balance, look at the leveling bubble on the floor of the weighing chamber. The balances are different from other scales in the sense that the weighing area is encased to protect it from the external factors. The analytical balance is a fundamental measuring device for all types of quantitative work in analytical chemistry. The glass draft shields are necessary to prevent drafts when weighing to this level of accuracy. A halogen lamp heats up the chamber to 199 °C / 390 °F. In addition, charge on powders being measured can cause the powder to be scattered in handling, making a mess.
