Among the most important pieces of equipment in the lab, high precision balances are used for a wide range of laboratory tasks such as formulation, density determination and quality control testing. They also help meet regulatory standards and propel breakthroughs across a variety of scientific and industrial disciplines.
When choosing a high precision balance for your application, consider the accuracy requirements of your work, as well as budget constraints and application specifics. An analytical or semi-analytical balance is recommended if you need a higher level of accuracy, while a precision balance offers superior sensitivity and readings within the 0.01-gram range.
The resolution of a balance refers to how fine the increments of mass are, and is often determined by the number of decimal places displayed. The higher the resolution, the more accurate the scale. A resolution of 0.1 gram or less is common in precision balances, and is sufficient for most general purpose weighing applications.
An important consideration when using a high precision balance is that the environment in which it is placed can influence its stability and accuracy. To avoid weighing errors, shield the instrument and samples from ambient drafts and vibrations, and ensure that the weighing area is clean and well-ventilated.
Regular calibration is also critical for assuring the accuracy of an analytical or semi-analytical balance. A good calibration procedure involves loading the balance with a known weight to assess its accuracy and adjust accordingly. Many newer balances offer an internal calibration feature that automatically loads a standard calibrant for you, eliminating the need to purchase and store external calibration masses. high precision balance
