4. When the tip is immersed in the angle to absorb liquid, try to keep it vertical, and the inclination angle should not exceed 20°;
5, the immersion depth of the tip;
6. After the tip is immersed in the liquid for aspiration, keep it in the liquid surface for one second and then move the tip gently away. This is especially important for large-capacity pipettes or sucking viscous samples.
7. Pipette the liquid at a uniform and continuous aspiration speed, and control the pipetting speed. Too fast will cause spraying, liquid or aerosol to rush into the pipette, contaminating the piston and other parts.
8. Draining and blowing liquid, first press the piston to the first gear to discharge the liquid, after a short pause, press to the second gear to blow the liquid.
