Bring confidence to your lab with the Ion BM Series of micro balances. With a capacity up to 520 g, or with readability down to 1 µg, the Ion BM Series can handle even trace quantities of valuable or degradable substances with confidence.

The fan-less, integrated, direct current ionizer eliminates static and comes standard on all Ion BM models. The automatic response adjustment function is powered by the embedded sensors to deliver fast and stable results to compensate for environmental variables such as temperature, humidity, vibration and atmosphere.

Weighing Capacity 22 g
Readability 0.001 mg
Repeatability (Standard Deviation) 0.0025 mg (repeatability using a 1 g weight within the weighing capacity)
Linearity ±0.010 mg
Minimum Weight (typical) 3.0 mg (pursuant to the United States Pharmacopoeia (USP), Chapter 4.1)
Stabilization Time (set to FAST) Approximately 10 seconds
Sensitivity Drift (10°C to 30°C) ±2 ppm / °C (when automatic self calibration is not used)
Operating Temperature 5°C to 40°C (41°F to 104°F), 85% RH or less (non-condensing)
Display Refresh Rate 5 times/second or 10 times/second
Measurement Units (Display Mode) g, mg, oz, ozt, ct, momme, dwt, GN, messghal, pieces (counting mode), % (percent mode), specific gravity (tael and tola can be added upon request)
Counting Mode Minimum unit mass = 0.1 mg / number of samples = 10, 25, 50 or 100 pieces
Percent Mode Minimum 100% ref. mass = 10.0 mg / minimum 100% display = 0.01%, 0.1%, 1% (depends on the reference mass stored)
