Frequently Asked Questions

What are the capacity and readability of the A&D BM-20 Micro Balance?

The A&D BM-20 has a maximum weighing capacity of 22 g with 0.001 mg (1 µg) readability across the entire weighing range. A&D specifies 0.0025 mg repeatability at a 1 g load and ±0.010 mg linearity. This combination makes the BM-20 suitable for elemental analysis, pharmaceutical research, environmental testing, filter weighing, and other applications requiring microgram-level measurements.

Does the A&D BM-20 have a built-in ionizer for static elimination?

Yes. The BM-20 incorporates a built-in fanless ionizer that helps neutralize electrostatic charges on samples and containers. This is particularly valuable at 1 µg readability because static electricity from filters, plastics, powders, or laboratory containers can cause unstable or inaccurate measurements. The balance also uses anti-static glass panes to further reduce electrostatic interference.

Does the A&D BM-20 have internal calibration?

Yes. The BM-20 features internal calibration with an automatic self-calibration function. The system can compensate for temperature-related changes, helping users maintain reliable weighing performance without routinely placing an external calibration weight on the balance.

What is the typical minimum weight of the A&D BM-20 under USP Chapter 41?

A&D specifies a typical minimum weight of 3.0 mg for the BM-20 pursuant to USP Chapter 41. This makes the balance particularly relevant to pharmaceutical and regulated laboratory applications involving very small samples. Actual minimum weight should still be determined under the user's installation conditions and applicable laboratory procedures.

What is the difference between the A&D BM-20 and BM-22 Micro Balance?

Both models have a maximum capacity of 22 g, but their weighing ranges differ significantly. The BM-20 provides 0.001 mg readability throughout its full 22 g capacity, while the BM-22 provides 0.001 mg readability up to 5.1 g and 0.01 mg readability from 5.1 g to 22 g. Therefore, the BM-20 is the better choice when 1 µg resolution is required even with heavier samples or containers.
