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.

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.

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.
