Corning Costar Centrifuge Tube 0.65 ml Attached Snap Cap PP 2000 Tubes

Corning 3206 Low-Binding Microcentrifuge Tube – 0.65 mL, Snap Cap, Polypropylene

The Corning 3206 is a high-performance 0.65 mL microcentrifuge tube engineered specifically for precision molecular biology and proteomics applications. Manufactured from optically clear, virgin polypropylene, these tubes feature advanced low-binding polymer technology that significantly reduces the adhesion of proteins, enzymes, and nucleic acids to the interior walls. This ensures maximum sample recovery and accurate quantitation, especially when working with low-concentration or highly valuable microscopic samples. Designed to withstand extreme centrifugal forces up to 17,000 x g, the tube is equipped with a secure, positive-seal snap cap that prevents popping and evaporation during rigorous boiling or high-speed spinning. Certified RNase- and DNase-free, the Corning 3206 provides a dependable, sterile-grade environment for the most sensitive laboratory protocols.

Technical Performance and Design

• Low-Binding Technology: Utilizes a proprietary bonded polymer surface (rather than temporary silicone coatings) to prevent sample loss due to plastic adherence, maximizing the yield of rare RNA transcripts or diluted protein assays.

• High-Speed Durability: Engineered with heavy-duty polypropylene and a reinforced conical base to safely withstand maximum Relative Centrifugal Forces (RCF) of up to 17,000 x g without cracking or structural failure.

• Positive-Seal Snap Cap: The attached, flat-top cap provides a highly secure, leak-proof friction fit that resists popping open during thermal cycling or extended incubation steps, yet remains easy to open with one hand.

• Clear Identification: Features distinct, molded external volume graduations for quick visual checks, along with a frosted writing panel on the side and a flat cap surface for easy, smudge-free sample labeling.

Key Benefits & Applications

• Proteomics & Enzymology: The go-to consumable for preparing protein dilutions, handling sticky enzymes, or conducting sensitive ELISA and mass spectrometry sample prep where standard tubes would cause sample loss.

• Nucleic Acid Recovery: Essential for RNA/DNA precipitation and purification protocols involving very low target concentrations or highly diluted genetic material.

• Micro-Volume Processing: The 0.65 mL size is perfect for conserving expensive reagents, reducing dead volume, and processing small aliquots that would otherwise get lost at the bottom of a standard 1.5 mL tube.

• Thermal Stability: Polypropylene construction allows the tubes to be safely autoclaved at 121°C or archived at ultra-low freezer temperatures (-80°C) without turning brittle.
