Hydrologix HLT 200 Pipette Tips SoftFit-L 200 ul Pack of 10 Racks

Thermo Scientific™ SoftFit-L™ 200 µL Non-Filtered Pipette Tips, Hinged Racks (3752-HR) – Pack of 10 Racks

The Thermo Scientific™ 3752-HR SoftFit-L™ is a premium, research-grade liquid handling consumable engineered specifically for seamless mechanical compatibility with Rainin® LTS® (LiteTouch™ System) pipettes. Featuring a specialized cylindrical collar and positive-stop architectural hub design, these tips deliver an exact, airtight fit that mirrors the precision and comfort of native LTS hardware while significantly reducing the finger forces required for tip attachment and ejection. Precision-molded from high-purity, ultra-clear virgin polypropylene, these 200 µL universal-style alternative tips are completely free of bioactive additives or molding release agents. Supplied as a convenient laboratory bench pack of 10 rugged hinged racks containing 96 tips each (960 tips total per pack), this non-filtered, non-sterile configuration is optimized for daily routine liquid handling, enzymatic assay preparations, and generic solution compounding.

Technical Performance & Architecture

• Rainin® LTS® Alternative Fit Alignment: Designed specifically with a custom cylindrical sealing matrix that integrates flawlessly with the unique geometric requirements of Rainin LiteTouch pipettes. This physical interface guarantees a secure friction lock with exceptionally low insertion effort, minimizing repetitive strain risks across high-frequency pipetting shifts.
• Optimized Fluid Release Kinetics: Molded with thin-walled, flash-free distal tip orifices to achieve excellent fluid delivery metrics. The precise interior geometry reduces surface-tension fluid holdback, ensuring highly accurate volume dispensing loops for non-viscous aqueous solutions.
• Automation-Ready Hinged Rack Interface: Tips are securely nested inside a robust, heavy-duty polypropylene hinged rack system. The rigid internal rack insert handles the downward mechanical pressures of multi-channel pipettes, while the locking lid mechanism prevents accidental dust contamination inside cleanroom benches.
• High-Contrast Volumetric Visual Aids: Features a color-coded internal rack insert plate (typically yellow-coded for the 200 µL volume index) to allow rapid tip capacity classification on crowded laboratory workstations. Inserts are stamped directly with part numbers and lot serialization codes for downstream compliance auditing.
