Precision Laboratory Balances

Analytical & Precision (0.1 mg / 0.0001 g) GLP / GMP / USP 41 Compliant NIST & ISO 17025 Traceable

Precision Laboratory Balances & Analytical Scales

Sub-milligram accuracy, motorized internal calibration, and draft-shielded measurement systems for pharmaceutical, educational, and industrial R&D laboratories.

Analytical Balances (0.1 mg)

Equipped with anti-static glass draft shields and electromagnetic force restoration load cells. Ideal for precise chemical compounding, analytical standard prep, and density determination.

  • Capacities: 60 g up to 320 g
  • Readability: 0.1 mg (0.0001 g)
  • Motorized internal auto-calibration (isoCAL / ProFACT)
  • Full GLP/GMP printout logging with time/date stamps

Top-Loading Precision Balances

Rugged open-pan balances combining higher load capacity with exceptional readability for formulation, batching, checkweighing, and pilot manufacturing.

  • Capacities: 220 g to 12,000 g (12 kg)
  • Readability: 0.001 g (1 mg) to 0.01 g
  • Fast 1-second stabilization time for high sample turnover
  • Chemical-resistant stainless steel weighing pans

Moisture Analyzers & Microbalances

Halogen-heated moisture balances for loss-on-drying (LOD) QA testing in food, feed, and plastics, plus semi-micro units down to 0.01 mg for filter weighing.

  • Moisture readability: 0.01% to 0.001% (0.1 mg)
  • Rapid circular halogen quartz heating elements
  • Multiple drying profiles: standard, fast, ramp, step
  • Direct export to LIMS, Excel, and laboratory printers
