Pipetinkärjen

Pipetinkärjen, often referred to as a pipette tip, is a disposable plastic accessory that attaches to the end of a pipette. Pipettes are laboratory tools used to accurately measure and transfer small volumes of liquids. The tip serves as a conduit for the liquid, ensuring that no contamination occurs between the pipette and the liquid being handled, and also prevents contamination of the pipette itself. Pipette tips come in a wide variety of shapes, sizes, and materials, designed to suit different applications and pipette models.

Common materials for pipette tips include polypropylene, which offers good chemical resistance. Filtered pipette tips are also available, featuring a porous barrier that prevents aerosols from entering the pipette shaft, thus protecting both the sample and the user from contamination. Sterilized pipette tips are crucial for applications in molecular biology, cell culture, and other sterile techniques where the prevention of microbial contamination is paramount. The process of ejecting the used tip is a standard part of pipetting procedure, ensuring that each transfer uses a clean and uncontaminated tip. This disposable nature of pipette tips is a key feature for maintaining experimental integrity and preventing cross-contamination in laboratory settings.
