5 The AD-4212B-PT can be used for the pipette volume range from 20 µL to 10000 µL
*
6 The minimum weighing value, 1mg, corresponds to approximately 1 µL. If a pipette volume is
1000 µL, a test can be performed with a resolution of 0.1%. If 200 µL, 0.5%.
Note) Make sure that the measurement environment is free from vibration, drafts and air from air conditioners.
