Rainin Pipette Tips 10 ul LTS 20 Racks with 96 Tips Each

The Rainin (Mettler Toledo) 30389226 Pipette Tip is a premium 10 µL consumable designed exclusively for the LTS (LiteTouch System) family of pipettes. While often physically capable of holding up to 20 µL, this specific catalog number corresponds to the Low Retention, Filtered, and Sterilized configuration, making it the gold standard for handling critical molecular biology samples. The tips feature Rainin's proprietary "superhydrophobic" fluoropolymer surface, which is not merely a coating but a modification of the polypropylene itself. This "Low Retention" property prevents viscous or low-surface-tension liquids (like enzymes, glycerol, or PCR master mixes) from clinging to the tip walls, ensuring that you deliver the exact volume you aspirated.

A defining characteristic of this product is the BioClean Ultra™ certification. Unlike standard sterile tips that are simply gamma-irradiated to kill bacteria, these tips are manufactured in a Class 100,000 cleanroom and rigorously tested to be free of a comprehensive list of contaminants: DNA, DNase, RNase, Endotoxin, ATP, Protein, Protease, and PCR inhibitors. This makes them safe for even the most sensitive proteomics and genomic applications.

The LTS design itself is ergonomically distinct; it replaces the traditional conical cone with a cylindrical nozzle that includes a positive stop. This drastically reduces the force required to load and eject the tip (by up to 85%), preventing the repetitive strain injuries often associated with "jamming" universal tips onto a pipette shaft. These tips are supplied in Hinged Racks (96 tips per rack, 10 racks per pack), which feature a dual-position lid that can be propped open for easy access or clicked shut to maintain sterility.
