*5 The maximum volume selectable for adjustable volume pipettes

*6 The AD-4212B-PT can be used for the pipette volume range from 1 L to 10000 L.

*7 The minimum weighing value, 1 mg, approximately corresponds to 1 L. If a pipette volume is

1000 L, a test can be performed with a resolution of 0.1%. If 200 L, 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”.
