Micro & Semi-micro Balances
Micro and semi-micro balances for ultra-low mass weighing with 1 µg–0.1 mg readability and 2–220 g capacity. Internal/external calibration, fast stabilization, GLP/GMP printouts and RS-232/USB/Ethernet connectivity.
- Readability: micro 1–10 µg (0.001–0.01 mg); semi-micro 0.01 mg (10 µg).
- Draft-shield chamber, short stabilization, automatic internal calibration.
- Anti-vibration & anti-static options (ionizer) for repeatable results.

Micro and semi-micro balances — buying guide
| Type | Typical readability | Typical capacity | Use case |
|---|---|---|---|
| Micro | 1–10 µg (0.001–0.01 mg) | 2–52 g | Filters, micro-dosing, reference standards |
| Semi-micro | 0.01 mg (10 µg) | 80–220 g | Assay prep, pharma QC, method development |
Good weighing practice
- Environment: anti-vibration table, draft control, stable temperature/humidity.
- Static: use an ionizer/anti-static tools for plastics and filters.
- Calibration & verification: internal or external with certified weights (OIML class E2/F1).
- Minimum sample weight: determine via repeatability test per USP/Ph. Eur. and document in GLP/GMP printouts.
- Connectivity: capture data to PC/LIMS via RS-232/USB/Ethernet.
