Use equipment and articles:
Electronic balance (measuring range 200g; graduation value 0.1mg); 1 beaker (50mL); 1 beaker (100mL); several small pieces of qualitative filter paper; 80mL ultrapure water.

(1) Turn on the electronic balance and adjust the zero load without load;
(2) Put the small beaker into the small beaker and wait for the balance display to stabilize, and then press the zero key to return to zero. Install the corresponding suction nozzle on the pipette, and pre-wash the pipette tip;[ 10ul Pipette Tip,5ml Pipette Tips,Pipette Tip 5 Ml,Pipette Tip 50ul, 200ul Filter Tips ]
(3) Adjust the capacity of the pipette to the point to be inspected. The inspected points generally choose the smallest, middle and largest capacity values. It can be a certain capacity point;
(4) Use a pipette to transfer the tested volume of ultrapure water to the small beaker of the balance;
(5) After the balance display is stable, immediately read and record the value displayed by the electronic balance at this time. After recording, reset the electronic balance to zero;
(6) Repeat 5 times to execute 3-5. After recording, adjust the capacity of the pipette to the next inspected point to continue. The inspected points are adjusted according to the principle from small to large.[ 10ul Pipette Tip,5ml Pipette Tips,Pipette Tip 5 Ml,Pipette Tip 50ul, 200ul Filter Tips ]
