Then press the button to the first stop to discharge the liquid, stop for a while and continue to press the button to the second stop to blow out the residual liquid, and finally release the button.

Reverse aspiration method:

Suitable for transferring highly viscous liquids, biologically active liquids, easily foaming liquids or very small amounts of liquids;

Tip immersion angle

Try to keep it vertical when aspirating, and the angle of inclination should not exceed 20°.

Tip immersion depth

P10uL: less than or equal to 1 mm;

P20uL, P100uL, P200uL: less than or equal to 2 mm;

P1000uL: less than or equal to 3 mm;

P5mL, P10mL: less than or equal to 4 mm.

Tip immersion time

After aspiration, keep it in the liquid surface for one second and then gently remove the tip.

Suction speed
