1. Preparation: Confirm the required pipetting volume and select the appropriate pipette model and capacity.
2. Install samples or reagents: Take the sample or reagent to be transferred into the tip of the pipette, taking care to avoid the generation of bubbles.
3. Transfer liquid: Insert the tip into the target container and gently press the button to release the liquid. Take care to keep the pipette parallel to the liquid surface to ensure accurate transfer volume.
4. Clean the pipette: After each transfer of liquid, use an appropriate cleaning solution to repeatedly pipette several times, and then rinse with deionized water.
