A&D BM-252 - 250g x 0.00001g Semi-Micro Balance
A&D BM-252 confidently handles even trace quantities of valuable or degradable substances. Critical to precision weighing is static control, which is why the direct current fanless ionizer is standard on all models.
Sample weighing is at the centre of many laboratory processes, and the A&D Ion Series provides the performance, and features, standard accessories to bring real convenience and efficiency to your lab. Automatic response adjustment function uses environmental data from built-in sensors, to compensate for the balance’s characteristics to deliver fast and stable results.
Calibration is also automated and always available with a single keypress. A range of accessories adds extra convenience.
BM-252 semi-micro balance has the performance and standard accessories to simplify microgram measurements. The Ion Series now makes microgram ( µg ) measurements accessible to all researchers and offers a real choice in microbalances.
