Thermo Scientific Pipette Tips ART 1000 ul REACH Sterile 32 Racks of 96 Tips Each

Thermo Scientific™ ART™ 1000 µL REACH™ Extended Length Non-Filtered Pipette Tips, Sterile Hinged Racks (3791-HR) – Case of 3,072 Tips

The Thermo Scientific™ 3791-HR is a premium, extended-length liquid handling consumable designed to provide enhanced access and contamination control when drawing fluid from deep vessels, narrow tubes, and deep-well blocks. Part of the industry-standard ART™ (Aerosol Resistant Tip) portfolio, the REACH™ series features an extra-long tip profile (1000 XL) that maximizes the physical clearance distance between the pipette barrel body and the sample vessel walls, preventing accidental contact and cross-contamination. Precision-molded from high-purity virgin polypropylene, these 1000 µL universal-fit pipette tips provide excellent accuracy and fluid release kinetics. Supplied as a massive commercial case of 3,072 tips (structured as 32 hinged racks containing 96 tips each), this sterile line is standard hardware for molecular biology, clinical diagnostics, and cell culture master mix dispensing.

Technical Performance & Architecture

• REACH™ Extended Length (1000 XL) Profile: Specifically lengthened compared to standard 1000 µL tips, allowing operators to easily reach the bottom of 15 mL conical tubes, tall reagent bottles, and deep 96-well culture blocks without risking pipette barrel contamination.
• Universal Friction-Fit Hub Geometry: The flexible, thin-walled tip sealing ring adapts to structural variations across various pipette brands. This design establishes an airtight friction seal with Thermo Scientific Finnpipette and F1/F2 lines, as well as pipettes from Biohit, Gilson, Rainin, and Eppendorf.
• Heavy-Duty Hinged Rack System: Tips are presented in rigid, automation-ready hinged racks with structural lock clasps. The robust lid design allows for simple one-handed opening and closing maneuvers inside biosafety hoods while maintaining structural stability against multi-channel pipetting forces.
• Validated Bio-Purity Profile: Every manufacturing lot undergoes independent certification to ensure the fluid paths are free from detectable nucleic acids and metabolic inhibitors. This strict purity validation helps protect critical enzymatic workflows from sample degradation.
