Six Major Operational Misunderstandings Using Pipettes

Pipettes are widely used in the laboratory. Proper operation and use of pipettes can improve work efficiency. What are the six common operational misunderstandings of pipettes? Pipettes are widely used in laboratories. The correct operation and the use of pipettes can improve work efficiency. What are the common 6 operating mistakes of using pipettes:

Misunderstanding 1. When assembling the tip, the force is too strong. The result is that the tip is difficult to be detached correctly: no need to use excessive force, select the tip that matches the pipette.

Misunderstanding 2. When pipetting, the pipette itself tilts: The pipetting is inaccurate and correct: vertical pipetting, slow suction and slow release.

Misunderstanding 3. Lay the pipette w ith a residual liquid tip. Consequence: The liquid reverses corrosion. The piston spring is correct: the pipette should be hung on the pipette holder.

Misunderstanding 4. Use a large-scale pipette to remove small volume samples. Consequences: Inaccurate pipetting. Correct: Pipettes with appropriate range should be selected.

Misunderstanding 5. directly press the second file to the correct absorption: it should be operated according to standard methods.

Misunderstanding 6. Cleaning the pipette with acetone or highly corrosive liquids: Damage to the pipette. The correct method: look at the instructions in detail, do not use corrosive liquids for cleaning. In the process of operating the pipette, be sure to avoid similar problems, bearing in mind the above six major misunderstandings.
