Pipette Tips for Zero Interference
For successful experiments, insist that your pipette tips are completely inert and won't interfere with your results. "Contamination-free"...
Rainin Pipette Tips
Rainin pipette tips fit most pipette brands, including a pipette tip for Rainin, Gilson, Eppendorf, Sartorius (BioHit), Thermo (Finn), and VWR pipettes.
Made from 100% virgin polypropylene in a fully automated, Class 100,000 clean room facility, Rainin tips provide excellent clarity and flexibility for accurate touch-off. To assure absolute purity, no additives or dyes are used, and we follow ISO 9001-compliant manufacturing procedures to eliminate all external sources of contamination.
"Our research involves growing bone marrow cells onto different materials. Rainin BioClean™ Filter Pipette Tips, which contain hydrophobic filters, are ideal for our purposes."
Dr Monica Tsimbouri, University of Glasgow’s Centre for Cell Engineering
"We focus on adenomatous polyposis coli (APC), a multi-functional protein with a role in a variety of basic cellular processes. We use Rainin BioClean™ Pipette Tips to ensure the precision of our experiments and to avoid contamination of highly sensitive PCR experiments and tissue cultures."
Ian Newton, Scientific Officer, Näthke lab, School of Life Sciences, University of Dundee
"We use LTS tips in our specialist diagnostic testing of cerebrospinal fluid. They are well made and not too rigid, and the design of the pipettes allows them to be picked up without using a lot of force."
Dr Roberta Bedin, Nuovo Ospedale S. Agostino Estense di Baggiovara, Modena, Italy
BioClean Ultra Pipette Tips for Zero Interference
To receive the industry-leading BioClean Ultra purity certification, Rainin pipette tips are subjected to systematic testing for RNase, DNA, DNase, ATP, Pyrogens, PCR inhibitors, trace materials and trace organics.
Rainin also tests for both protein and protease to fuel confidence in proteomics research. And every tip is also inert, with no bioactive components.
Class 100,000 Clean Room Production
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 guaranteed to be pure and completely safe.
For successful experiments, insist on pipette tips that won't interfere with your results.
Make sure they're BioClean Ultra.
LiteTouch System and Universal Fit
Rainin tips optimize work with different kinds of pipettes:
● LTS: Rainin LiteTouch System™ pipettes
● UNV: Universal-fit pipettes, by Rainin and other manufacturers.
Unique to Rainin, the LiteTouch System connects a specially shaped nozzle to a perfectly matched LTS tip to deliver the industry's lowest tip mounting and ejection forces. The result: fewer repetitive stress injuries and more comfort while pipetting.
Pipette Tips by Package Type
Rainin pipette tips are available in a variety of packaging formats to suit your lab's needs.

In our brief Pipette Tips FAQ you will find answers to the most frequently asked questions, for example
What are pipette tips?What is BioClean and pipette tip sterility?
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 and pipette tip sterility??
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.
Sterility refers to the absence of bacteria or any living microorganisms or spore, but without an additional qualifier (such as BioClean) 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.
