Pipette Dispensing and Post-Operation Best Practices (Part 2)

In laboratory environments, improper dispensing and handling can compromise both accuracy and equipment lifespan. Even small mistakes—such as incorrect tip positioning or improper storage—can lead to contamination, backflow, or mechanical damage.

• Proper Dispensing Technique

During dispensing, the pipette tip should be placed against the inner wall of the receiving container. This ensures smooth liquid transfer and minimizes residue.

• Controlled Plunger Release

Release the plunger slowly and steadily to ensure complete and accurate liquid delivery without splashing or air introduction.

• Safe Tip Ejection

After dispensing, gently press the tip ejector to safely discard the used tip and avoid contamination.

• Protecting the Pipette Mechanism

After use, always reset the volume to the maximum setting. This helps protect the internal spring system and maintains long-term performance.

• Proper Storage

To prevent liquid backflow and internal contamination, always place the pipette on a dedicated stand after use.

• Calibration and Maintenance

Regular calibration and maintenance are essential to ensure consistent accuracy and compliance with laboratory standards.

Proper pipette handling does not end with aspiration. During dispensing, the tip should be placed against the inner wall of the receiving container to ensure smooth liquid transfer. The plunger must be released slowly and evenly to maintain accuracy. After dispensing, eject the tip gently to avoid contamination. To protect the internal mechanism, reset the pipette to its maximum volume after use. Additionally, always store the pipette on a stand to prevent liquid backflow. Regular calibration and maintenance are crucial for ensuring long-term performance and reliable results in laboratory applications.
