Tips for Precious Samples and Demanding Applications
Pipette tips are small, cone-shaped structures that fit on the end of a pipette. Scientists use pipette tips to transfer precise volumes of liquid from one vessel to another. Pipette tips are commonly discarded after each use to prevent cross-contamination. Rainin pipette tips are made from 100% virgin polypropylene and rigorously tested and inspected to ensure they meet the industry's highest purity standards.

What are pipette tips?
Pipette tips fit on the end of a pipette, creating an air-tight seal. Commonly made from polypropylene, they are made for one-time use and are available in a variety of formats and volumes to fit specific applications and pipettes.
Because they come in direct contact with the sample of interest, pipette tips can have a significant effect on the results of an experiment. Discarding the tips between each experimental step helps prevent cross-contamination.
What is BioClean Ultra?
BioClean refers to the exceptionally high standard to which all Rainin air-displacement tips are tested and found to be free of detectable amounts of specific biological contaminants, such as DNA (human and bacterial), RNase, DNase, endotoxin, protein, protease, ATP and PCR inhibitors.
BioClean Ultra pipette tips are manufactured in a fully automated class 100,000 clean room facility. To assure absolute purity, no additives or dyes are used, and ISO 9001-compliant manufacturing procedures are followed to eliminate all external sources of contamination. From raw material selection to clean production and automated packaging, Rainin BioClean Ultra pipette tips are pure and completely safe.
What is pipette tip sterility?
Pipette tip sterility refers to the absence of bacteria or any living microorganisms or spore, but without an additional qualifier (such as BioClean Ultra) can still contain contaminants that can have an influence on the outcome of an experiment. Reaction conditions and experimental results can be compromised by organic and non-organic contaminants unknowingly introduced to liquid samples by non-certified pipette tips. Contaminants can inflict adverse, unpredictable effects on enzyme activity and longevity, molecular interaction, spectrophotometric and chromatographic analysis, and more.
