Corning Costar Microcentrifuge Tube 2 ml Case of 1000 Tubes

Corning Costar 2.0 mL Snap-Cap Microcentrifuge Tubes (3213) – Case of 1000

The Corning Costar 3213 is a premium, industrial-grade microcentrifuge tube designed for high-velocity sample separation, daily diagnostic compounding, and biological fluid storage. Molded from high-clarity virgin polypropylene, these 2.0 mL tubes feature a precision-engineered conical bottom layout optimized for pellet extraction. Delivered non-sterile in a high-volume facility case of 1000 tubes (typically packed as two bags of 500), they provide excellent structural integrity under extreme centrifugal stress and are certified RNase-/DNase-free to ensure strict validation compliance.

Technical Performance & Design

• High-Velocity RCF Performance: Structural thickness allows the tube to safely withstand maximum relative centrifugal forces (RCF) up to 17,000 × g in compatible microcentrifuge rotors without wall structural failure.
• Positive Snap-Seal Integrity: Outfitted with a heavy-duty, push-fit snap cap engineered with an optimized sealing lip that prevents accidental pop-open evaporation during thermal cycles while facilitating reliable repeated openings.
• Molded External Graduations: Features high-contrast external volume markings molded cleanly into the clear cylinder wall alongside a frosted writing pad to ensure rapid, error-free sample identification.
• Flat-Profile Labeling Surface: Designed with an ultra-flat cap top surface that provides an ideal surface for permanent markers, automated barcode dots, or adhesive labeling tags.

Key Benefits & Applications

• Molecular & Genomic Assay Support: Perfect for building master reagent mixes, extracting genomic DNA/RNA fragments, or hosting long-term cell lysate suspensions.
• Autoclave Sterilization Flexibility: Supplied non-sterile, allowing quality control units to batch-autoclave quantities or directly integrate the tubes into protocols where pre-sterilization is unneeded.
• Universal Rotor Fitting Dimensions: The standard 0.500-inch outer diameter (O.D.) geometry maps cleanly across major modern benchtop microcentrifuge fixed-angle and swinging-bucket rotors.
• Contaminant-Free Compounding: Natural, uncolored raw material compound formulation completely avoids colorant pigment leaching anomalies that can interfere with sensitive spectrophotometric micro-volume determination readouts.

If your assay matrix demands chemical-proof threading for ultra-volatile solvents, alternative screw-cap microcentrifuge configurations should be sourced independently.
