pipettikärkien

Pipettikärkien, commonly known as pipette tips, are disposable plastic accessories used with pipettes. Pipettes are laboratory instruments designed to accurately measure and transfer small volumes of liquids. Pipette tips are essential for this process as they form the interface between the pipette and the liquid being handled, preventing contamination of both the pipette and the sample.

These tips are manufactured from materials like polypropylene to ensure chemical resistance and minimize liquid adhesion. They come in a wide variety of sizes and shapes to accommodate different pipette volumes and applications, ranging from very small volumes (microliters) to larger volumes (milliliters). Features such as filtered tips, which contain a porous barrier to prevent aerosol contamination, and low-retention tips, designed to minimize sample loss due to surface tension, are also available for specialized tasks.

Pipette tips are typically supplied in racks or bulk packaging. After each use, or when changing solutions or samples, the tip is ejected and discarded to maintain aseptic conditions and prevent cross-contamination. This disposable nature is a key aspect of their function, contributing to the reproducibility and reliability of experimental results in fields such as molecular biology, chemistry, and medicine. The proper selection and use of pipette tips are fundamental to accurate liquid handling in laboratory settings.
