Industry And Product News

Rainin BioClean Ultra pipette tips ensure top pipetting performance through innovative design and high quality production.


Clean pipette tips are critical in liquid handling and research applications to ensure high quality lab results. Pipette tips coming into contact with samples must be free of DNase, RNase, DNA, pyrogens, adenosine triphosphate (ATP), PCR inhibitors, trace materials and trace organics. Understanding these typical sample contaminants, and taking precautionary measures to reduce or eliminate them at their source, is vital to protecting sample integrity.

Exceptionally Pure

METTLER TOLEDO’s Rainin BioClean Ultra pipette tips are manufactured from virgin polypropylene material in a fully automated, Class 100,000 clean room facility.  These flawless tips are 100% contamination-free, ensure absolute purity and safety, preventing experiment inconsistencies and failures.  And they are also inert, with no bioactive components.

 BioClean Ultra Certification

Rainin fully certifies the absence of external contaminants in BioClean Ultra tips, including protein and protease to support proteomics research. Certificates are available for download at  and include detection level requirements and testing methods used. 

LTS Tips

Rainin’s LTS tip range are manufactured with continuous tapering and thin-walled construction to give greater flexibility, a softer feel and a better performance than standard or beveled tips. Traditional tips are also offered with a conical design to fit pipettes of all standard manufacturers, such as Eppendorf, Gilson, Sartorius (BioHit), Thermo (Finn), as well as the traditional non-LTS Rainin pipettes.

With a wide array of tips, available in a variety of feature-sets (like filter tips), volume ranges and packaging options to select from, scientists can work with the most optimal application-specific pipetting system.

Applications: BioClean Ultra, Life Sciences, Liquid Handling, Pipette Tips, Pipettes, Pipetting, Proteomics
