Novex Round Gel Loading Tips 200 ul 4 Racks of 200 Tips Each

Invitrogen™ (Novex) Standard Round Gel Loading Pipette Tips, 200 µL (LC1001) – Pack of 4 Racks

The Invitrogen™ LC1001 Standard Round Gel Loading Tips (historically cataloged under the legacy Novex brand) are precision-fabricated, specialty fluid handling consumables designed for the efficient deposition of macromolecular samples into electrophoresis gels. In contrast to flattened duckbill variations, these tips feature a classic cylindrical round capillary micro-orifice optimized for navigating standard vertical polyacrylamide and horizontal agarose gel wells. Precision-molded from high-purity virgin polypropylene, these 200 µL tips balance physical structural rigidity with a narrow distal profile to easily target 1.0 mm and 1.5 mm gel tracks (such as those in Invitrogen™ NuPAGE® or Bolt™ mini-gel tanks). Supplied as a multi-rack workspace package of 4 racks containing 200 tips each (800 tips total per package), this non-sterile, open-channel tip line provides low fluid holdback and excellent sample volume delivery for routine SDS-PAGE, western blotting, and nucleic acid fragment analysis.

Technical Performance & Structural Architecture

• Standard Round Capillary Orifice Profile: Formulated with a specialized, narrow round barrel taper that provides consistent linear fluid flow. This geometry makes it ideal for loading samples into standard 1.0 mm and 1.5 mm cross-linked acrylamide matrices without creating disruptive cross-current turbulences.
• Universal Friction-Fit Sealing Hub: Engineered with a compliant, flexible upper mounting collar that establishes a gas-tight friction seal across major single-channel mechanical pipettor brands, including Eppendorf Reference/Research, Gilson Pipetman, and Thermo Scientific Finnpipette lines.
• Elongated Macro-Reach Displacement: Features a distinctly elongated, slim-line barrel design. This structural length enables deep well immersion while keeping the non-sterile pipette shaft well clear of running buffer pools, preventing liquid carryover and cross-contamination.
• Certified Chemical and Bio-Purity: Every production lot is certified to be completely free of detectable RNase and DNase contamination. This strict manufacturing oversight guarantees that target proteins and nucleic acids are shielded from enzymatic breakdown during setup.

Key Benefits & Applications

• Precast Protein Gel Track Seeding: The default round-tip choice for loading denatured protein specimens into NuPAGE Bis-Tris mini-gels or traditional pouring cassettes without catching or tearing the delicate well partitions.
• Horizontal Nucleic Acid Agarose Runs: Excellent for submerged horizontal electrophoresis setups, allowing the user to precisely sink dense, glycerol-weighted DNA/RNA restriction fragments straight to the bottom of the well.
• High-Clarity Meniscus Verification: The glass-clear polypropylene matrix allows immediate, real-time monitoring of boundary travel, ensuring all sample volume is fully expelled without leaving a structural fluid heel behind.
• **High-Density Benchtop Presentation:** Packed in an efficient 200-count array pattern per rack box to optimize space under laminar flow hoods and minimize container swap cycles during high-throughput screening assays.
