Corning Centrifuge Tube 15 ml Plug Seal Cap Polypropylene Case of 500 Tubes

Corning® 15 mL Clear Polypropylene Conical Centrifuge Tubes, Plug Seal Caps (430766) – Case of 500

The Corning® 430766 is a premier, research-grade fluid handling consumable engineered for high-velocity sample centrifugation, chemical cell separation, reagent storage, and general laboratory liquid logistics. Precision-molded from premium, high-density virgin polypropylene, these 15 mL conical tubes exhibit high chemical resistance across range of acids, bases, and organic solvents. The system integrates a traditional, ribbed **polyethylene plug seal cap** that provides a gas- and liquid-tight mechanical compression fit to completely suppress fluid weeping or sample aerosolization under extreme centrifugal forces. Arriving as a commercial facility case of 500 tubes organized in space-saving bulk bags of 50, this sterile, single-use configuration is standard hardware for high-throughput cleanrooms, biochemistry lines, and diagnostic biobanks.

Technical Performance & Material Architecture

• High-G Mechanical Rating: Advanced structural molding enables the conical polypropylene base to withstand physical acceleration stresses up to 12,000 x g (RCF) inside balanced fixed-angle or swinging-bucket centrifuge rotors, avoiding structural fracturing.
• Deep-Molded Plug Seal Cap Geometry: Outfitted with an orange, high-density polyethylene (HDPE) screw cap featuring an interior cylindrical plug seal. This seal extends down into the tube neck, creating a tight dual-surface boundary that prevents evaporation and leakage under intense deep-freeze or vacuum conditions.
• High-Contrast Volumetric Markings: Printed with highly legible, dark black ink graduations running from 1.5 mL up to 14.5 mL in precise 0.5 mL increments. The tube also incorporates a broad, white printed marking spot that resists organic solvent wipes for secure, permanent hand-written sample indexing.
• Bulk Bagged Aseptic Management: Packaged in durable, heavy-gauge polymer bulk bags containing 50 tubes each (10 bags per case). This layout permits rapid benchtop distribution while keeping remaining backup inventory sealed and isolated from ambient atmospheric particulates.

Key Benefits & Applications

• Pelleting and Cellular Fractionalization: The optimal structural choice for separating blood components, harvesting cell pellets from tissue culture expansions, and concentrating nucleic acid precipitates.
• Cryogenic and Cold Room Archive Storage: Heavy-walled polymer construction allows for safe sample storage down to standard vapor-phase storage parameters, preventing cold-shock stress fractures.
• Reagent Distribution and Master Mix Aliquoting: Serves as an excellent, chemically inert container for compounding working stocks of buffers, media additives, or fluorescent assay probes under a biosafety hood.
• **cgmp Facility Lot Traceability:** Every manufacturing master carton is marked with a unique lot code, ensuring flawless, audit-ready product tracking across industrial medical and pharmaceutical laboratory networks.

Corning® is a registered commercial trademark of Corning, Inc. Catalog number 430766 specifies the bulk bagged 15 mL polypropylene tube with an orange plug seal cap. For single-handed operational loops where a flat cap profile is preferred for top-surface marking, or for applications needing standalone racks, companion CentriStar™ cap configurations or pre-racked styrofoam variants must be integrated into the supply loop instead.
