Semi-micro balance BH-225TE – Premium precision without compromise

The BH-225TE from A&D's premium BH-T/BH series redefines the highest standards for analytical balances. With exceptional readability of 0.01 mg (10 µg) and state-of-the-art operating technology, it is the perfect choice for the most demanding weighing tasks in research, analysis, and quality control.

Technical excellence:

• Spring-damped weighing plate as shock absorber

Highly precise wind protection

• Large work area with perforated weighing platform (Ø 90 mm)
• 2 wind protection rings: high (max. protection) and low (for weighing paper/filters)
• Groove-free side door design (top-hung) – easiest cleaning
• Fully disassemblable via clip system (all glass panes + base plate)
• Cleaning brushes (large + small) included in the scope of delivery

Advanced application modes

• Formulation mode: Recipe management for multi-component mixtures (up to
• 150 samples, 300 recipes), with tolerance testing
• HPLC mode: Buffer solution preparation with molar concentration (mol/L, mmol/L),
• Automatic conversion via molecular weight
• Density determination: Solid/liquid density with accessory AD-1653 (optional) or
• Underfloor weighing
• Repeatability test (P-TEST): Rapid performance testing under
• Operating conditions

Daily/Periodic Scale Checks (SOP Support)

• Step-by-step instructions for Daily Check (spirit level, environment, SRC, weighing platform, accuracy)
• Periodic checks: eccentricity measurement, calibration test, repeatability,
• Sensitivity test
• PDF reports can be saved to a USB stick.
• Configurable reminder function

Minimum weight management

• Direct entry or automatic calculation (0.1% USP 41 or 1% tolerance)
• Continuous alarm until minimum weight is reached
• Optional data output lock below minimum weight
• Detailed measurement report exportable

GLP/GMP compliance and data management

• GLP Custom Output: Freely configurable output templates (header/body/footer)
  
• Label mode: ZPL/ZPL II compatible label printers, text + barcode (CODE128)
