Pipettitippejä

Pipettitippejä, often referred to as pipette tips, are disposable plastic consumables used with pipettes to accurately transfer small volumes of liquid. They are a crucial component in laboratories across various scientific disciplines, including molecular biology, chemistry, and medicine. The primary function of a pipette tip is to provide a sterile, inert, and precise interface between the pipette and the liquid being handled.

Pipette tips come in a wide array of sizes and designs, tailored to specific pipette types and applications. Common materials include polypropylene, which offers good chemical resistance and is autoclavable. Tips can be filtered or non-filtered. Filtered tips contain a porous plug that prevents aerosols and contaminants from entering the pipette, thereby protecting both the sample and the instrument. Non-filtered tips are simpler and generally used when aerosol contamination is not a significant concern.

Tips are typically manufactured in cleanroom environments to ensure sterility and minimize particulate contamination. They are often packaged in racks or bags, which can be sterile or non-sterile depending on the intended use. Sterility is particularly important for applications involving biological samples or sensitive reagents. Pipette tips are designed to fit securely onto the pipette's cone, forming a seal that allows for accurate aspiration and dispensing of liquids. The volume range a tip can accommodate depends on its size, with smaller tips designed for microliter volumes and larger tips for milliliters. Proper selection and use of pipette tips are essential for achieving reproducible and reliable experimental results.
