Molded from 100% virgin, bio-inert polypropylene, these tips feature a specialized SoftFit-L design that ensures an airtight, consistent seal with minimal mounting and ejection force, drastically reducing user hand fatigue. Enclosed in heavy-duty hinged racks that protect against benchtop airborne contaminants, these tips incorporate the proprietary ART (Aerosol Resistant Tip) self-sealing barrier. Certified completely free of RNase, DNase, DNA, and pyrogens, they deliver the absolute volume accuracy and cross-contamination protection required for high-sensitivity molecular assays.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eRainin LTS System Architecture:\u003c\/b\u003e Precision-engineered to match the unique cylindrical nozzle and thin-rim retention ring specifications of Rainin LTS pipettes, guaranteeing straight vertical tip alignments and perfect tip-to-tip uniformity on multichannel models.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eART Self-Sealing Barrier:\u003c\/b\u003e Unlike standard porous filters that merely slow down aerosol entry, the internal ART barrier allows clean air to pass freely during normal aspiration, but completely locks and traps liquids or harmful aerosols if an accidental over-pipetting event occurs.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eRigid Hinged Rack Layout:\u003c\/b\u003e Supplied in a robust, color-coded yellow hinged rack that holds the individual tips perfectly vertical, preventing tip deflection when multi-channel pipettor heads snap into place.
