Thermo Scientific Centrifuge Tube Conical 15 ml 100 Centrifuge Tubes

Thermo Scientific Nunc 339650 Conical Centrifuge Tubes – 15 mL, Sterile, Polypropylene, Bulk

The Thermo Scientific Nunc 339650 is a premium 15 mL conical centrifuge tube engineered for high-performance sample separation, chemical compounding, cell culture processing, and biological liquid archiving. Molded from ultra-pure, clarified virgin polypropylene (PP), this tube combines exceptional chemical tolerance with high-speed mechanical strength, rated to withstand rigorous centrifugation forces up to 10,500 × g. Featuring a secure HDPE plug-seal screw cap, it guarantees an absolute leak-proof closure. It also includes crisp, high-contrast black graduations and the largest integrated matte writing area available on the market to ensure rapid labeling and absolute sample traceability.

Technical Performance and Design

• Super-Speed Centrifugation (10,500 × g): Precision-engineered wall uniformity and high-purity resins allow this tube to handle low-speed pelleting up to high-speed separation protocols ($\text{Max RCF} = 10,500 \times g$) when fully supported by a standard conical rotor cavity.

• Maximized Traceability Writing Grid: Features an extra-large white matte marking patch that provides extensive surface area for detailed sample documentation, dating, and logging, minimizing tracking identification errors on busy lab benches.

• Hermetic Plug-Seal Cap: The blue, high-density polyethylene (HDPE) cap features an inner plug geometry that drives into the inner rim of the tube barrel. This creates a secure, leak-proof mechanical isolation layer to isolate dangerous biohazards and volatile liquids.

• Certified Biological Cleanliness: Cleanroom-molded to strict ISO quality standards, these tubes are gamma-sterilized to a high Sterility Assurance Level (SAL 10⁻⁶) and are strictly certified non-pyrogenic, non-cytotoxic, and RNase/DNase-free.

Key Benefits & Applications

• Cell Culture Processing: The cleanroom standard for pelleted mammalian cells, chemical harvesting, washing suspension lines, and splitting primary cell matrices without chemical leaching risks.

• Aqueous Solvent and Buffer Archiving: Broad polymer compatibility shields sample contents from organic extractable leachates, preserving delicate enzyme configurations, nucleic acid libraries, and mass spectrometry standards.

• High Volumetric Resolution: Imprinted with permanent, dark black bi-directional graduation markings running from 2 mL up to 14.5 mL (0.5 mL increments) alongside molded baseline marks for quick volumetric confirmation.

• Glass Replacement Safety: Completely eliminates the high-consequence laboratory hazard of broken glass shrapnel and chemical spill exposure under high rotational strain inside benchtop centrifuges.
