Pipette tips help to create a reliable and accurate pipetting system. These tips are injection molded plastic and are disposable. Pipette tips come in several types including pre-sterilized, filtered and non-sterilized tips. Pre-sterilized tips are often used in applications where absolute sterility is a necessity such as cell cultures.
Filtered tips are often aerosol resistant which helps prevent contamination. These tips are often used for forensics and clinical diagnostics in order to protect these samples against contamination. Non-sterile tips are used for applications where sterility is not critical. Most of these pipette tips can come as RNase and DNase free.
