Description

A&D Scale PN BM-5

A&D Scale PN BM-5 is a professional single-range microbalance with internal calibration and a built-in fanless ionizer, designed for ultra-precise weighing in laboratories, pharmaceutical facilities, research institutions, environmental analysis, chemical testing, quality control, cannabis testing, manufacturing, and other demanding scientific applications. The BM-5 provides a 5.2 g maximum capacity with 0.000001 g (0.001 mg / 1 µg) readability across its weighing range, delivering true microgram-level measurement performance for applications where extremely small changes in mass must be measured accurately. Unlike the dual-range BM-5D, the BM-5 maintains its 1 µg readability throughout its full 5.2 g capacity.

A major advantage of the A&D BM-5 is its built-in direct-current fanless ionizer, which helps neutralize static electricity that can interfere with microgram-level weighing. Electrostatic charges on powders, plastics, filters, containers, pharmaceutical ingredients, films, and other materials can cause unstable readings and measurement errors. The integrated ionizer helps reduce this interference directly within the weighing workflow, while its fanless design avoids introducing additional air movement around extremely sensitive samples. Anti-static metal-coated glass further helps reduce the effects of external electrostatic interference.

The BM-5 provides a 5.2 g capacity, 0.001 mg readability, 0.0012 mg repeatability at 1 g, ±0.010 mg linearity, and a typical minimum weight of approximately 2.0 mg under A&D’s stated USP Chapter 41 methodology. These specifications make the BM-5 particularly well suited for elemental analysis, mass analysis, pharmaceutical research, reference-material preparation, environmental testing, filter weighing, chemical analysis, and other applications requiring dependable microgram-level measurements.

Designed for extremely sensitive measurements, the BM-5 features a Ø25 mm weighing pan within a protected weighing environment engineered to minimize the effects of drafts, vibration, static electricity, and other environmental disturbances. The balance includes a large weighing chamber, interlockable sliding doors, and a removable separation plate to accommodate different sample vessels and specialized weighing procedures. A&D also offers specialized accessories for filter weighing and microfuge tubes, expanding the BM-5’s usefulness across a wide variety of scientific applications.

The BM-5 includes motor-driven internal calibration with automatic self-calibration, helping maintain weighing accuracy as environmental conditions change. Users can also initiate calibration when required, reducing the need to routinely handle separate external calibration weights. Automatic Response Adjustment helps optimize balance performance for conditions involving drafts and vibration, supporting more stable measurements under actual laboratory conditions.

For professional laboratory workflows, the BM-5 supports advanced data-management and compliance-oriented functions. The balance can store weighing information and supports output designed for GLP, GMP, GCP, and ISO-oriented workflows. Its microgram-level resolution makes it particularly valuable for laboratories performing quantitative analysis, pharmaceutical research, environmental testing, filter measurement, elemental analysis, and other procedures where very small changes in mass must be accurately detected.

Standard RS-232C and USB connectivity allows the BM-5 to communicate with compatible computers, printers, laboratory software, and data-collection systems. These interfaces help streamline weighing-data transfer and documentation while supporting integration into professional laboratory workflows. Combined with its microgram resolution, internal calibration, static-control technology, and protected weighing chamber, the BM-5 provides a comprehensive solution for laboratories requiring reliable ultra-precision measurements.

Whether you’re performing pharmaceutical research, elemental analysis, environmental testing, chemical analysis, laboratory sample preparation, cannabis testing, filter weighing, static-sensitive material measurement, or other ultra-precision scientific work, the A&D Scale PN BM-5 delivers the sensitivity and advanced functionality required for demanding micro-weighing applications. Its 5.2 g capacity, 0.001 mg (1 µg) readability across the full weighing range, built-in fanless ionizer, automatic internal calibration, Ø25 mm weighing pan, anti-static weighing environment, and professional connectivity make it a powerful solution for microbalance applications.
