Details

Weighing is at the heart of many laboratory processes and the Ion Series offers the features, performance and standard accessories to bring real convenience to your lab. With the six balances of the Ion Series, you can choose a capacity as high as 520 g or a micro-balance with readability down to 1 µg. The BM-20 and BM-22 let you handle with confidence even trace quantities of valuable or degradable substances.

Critical to precision weighing is static control, which is why the direct current fan-less ionizer is standard on all models

The automatic response adjustment function uses environmental data from built-in sensors to compensate the balance’s characteristics to deliver fast and stable results. Calibration is also automatic and always available with a single key press. A range of accessories add extra convenience.
