*4 The maximum volume selectable for adjustable volume pipettes
*5 The AD-4212B-PT can be used for the pipette volume range from 20 μL to 10000 μL.
*6 The minimum weighing value, 1 mg, approximately corresponds to 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 Pipette accuracy testing is performed using a high-resolution valance. Make sure that
the measurement environment is free from vibration, drafts and air from air
conditioners. For details, refer to “3. PRECAUTIONS BEFORE USE”.
