Pipette tips are small, disposable attachments used with pipettes to accurately transfer liquids in laboratories. They come in various sizes to accommodate different volumes, ensuring precise measurements for experiments and tests. The tips are typically made from plastic and are designed to fit securely onto the pipette, preventing leaks and contamination. Using the correct pipette tip is essential for maintaining the integrity of samples and achieving reliable results. Some tips are filtered to prevent aerosols from entering the pipette, while others are designed for specific applications, such as PCR or cell culture. Proper selection and handling of pipette tips contribute to effective laboratory practices.
