The balances are different from other scales in the sense that the weighing area is encased to protect it from the external factors. Many investigators simply zero out this effect and 642 product(s) found. Analytical balances have a draft shield or weighing chamber to prevent the very small samples from being affected by air currents. In addition, charge on powders being measured can cause the powder to be scattered in handling, making a mess. 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 balances are highly sensitive lab instruments designed to accurately measure mass. Although some might describe an analytical balances as a " lab balance " this is really too vague and we rather say "a four (4) decimal place balance". May 22nd, 2019 Kevin Hill. The TW and TX Series of analytical balances feature easy operation and added functionality. There are many other types of balances available on the market not covered in todayâs article.
