## 1. What are the key components of a pipette that need regular maintenance?

Proper maintenance of a pipette is essential to ensure accurate and reliable results in the lab. Key components that require regular maintenance include the piston, seals, tip ejector, and calibration settings. The piston and seals need to be kept clean and lubricated to ensure smooth operation and prevent contamination. The tip ejector should be checked regularly for any obstructions or damage that could affect its function. Calibration settings should also be monitored and adjusted as needed to maintain accuracy.

## 2. How can you clean and sterilize a pipette correctly?

To clean and sterilize a pipette correctly, you should first disassemble the pipette according to the manufacturer's instructions. Clean each component thoroughly with a mild detergent and water to remove any residue or contaminants. Rinse the components with distilled water to ensure they are free of soap or detergent. Once cleaned, the components can be sterilized using methods such as autoclaving, UV radiation, or chemical disinfection. It is important to follow proper sterilization protocols to prevent cross-contamination and ensure the accuracy of your pipette.

## 3. What are some common mistakes to avoid when handling and storing a pipette?

When handling and storing a pipette, there are several common mistakes to avoid. One of the most common errors is dropping or mishandling the pipette, which can damage delicate components such as the piston or seals. It is important to always handle the pipette with care and use it according to the manufacturer's guidelines. Another mistake to avoid is storing the pipette with liquid in the tip, which can cause contamination and affect accuracy. Always ensure that the pipette is stored in a clean, dry place with the tip facing upwards. Additionally, using the wrong size or type of pipette tip can lead to inaccurate results, so it is important to use the correct tips for your specific pipette model. By avoiding these common mistakes and following proper maintenance practices, you can extend the life of your pipette and ensure reliable performance in the lab.
