Constructed from high-clarity, medical-grade polypropylene, these tubes feature a free-standing, skirted base that allows them to remain upright on the benchtop without the need for a rack. Equipped with a secure screw cap and an integrated O-ring seal, the 16466-058 provides a leak-proof barrier against evaporation and contamination. These tubes are engineered to withstand extreme thermal stresses, making them suitable for everything from boiling water baths to vapor-phase liquid nitrogen storage.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eFree-Standing Skirted Base:\u003c\/b\u003e The stable, flat-bottom exterior allows the tube to stand independently, facilitating easier one-handed additions and reducing the risk of benchtop spills.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eO-Ring Screw Cap Seal:\u003c\/b\u003e Features a precision-fitted ethylene propylene (EP) O-ring within the cap to ensure a pressurized, airtight seal that prevents leakage during high-speed centrifugation or vortexing.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHigh-Centrifugation Stability:\u003c\/b\u003e Rated for high G-forces, the robust wall thickness prevents tube failure and ensures sample integrity even during intensive pelleting protocols.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eUltra-Low Temperature Resilience:\u003c\/b\u003e Designed for use in temperatures ranging from -196°C to +121°C, providing a versatile solution for both cryogenic freezing and autoclaving.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 16466-058\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVolume Capacity:\u003c\/b\u003e 2.0 mL\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaterial:\u003c\/b\u003e USP Class VI Polypropylene\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBase Style:\u003c\/b\u003e Free-Standing (Skirted)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCap Type:\u003c\/b\u003e Screw Cap with O-Ring\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eColor:\u003c\/b\u003e Natural\/Clear\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Sterile (Verify your specific lot)\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eClinical Sample Collection:\u003c\/b\u003e The self-standing design and secure seal are ideal for collecting and transporting sensitive patient specimens, including sputum, urine, or blood derivatives.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBiobanking and Storage:\u003c\/b\u003e Optimized for long-term preservation in ultra-low temperature freezers, ensuring that valuable biological extracts remain protected from desiccation.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eProteomics and Genomics:\u003c\/b\u003e Certified free of detectable DNase, RNase, and human DNA, making these tubes suitable for high-purity molecular biology workflows.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eChemical Stability:\u003c\/b\u003e Resistant to a broad spectrum of laboratory reagents, including alcohols and DMSO, ensuring no leachables interfere with analytical results.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"VWR","offers":[{"title":"Default Title","offer_id":44498011980028,"sku":"4116","price":185.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/vwr-centrifuge-tube-2-ml-free-standing-screw-cap-sealed-1000-tubes-centrifuge-tubes-vwr-780823.jpg?v=1766304381","url":"https:\/\/lifesciencestrading.com\/products\/vwr-centrifuge-tube-2-ml-free-standing-screw-cap-sealed","provider":"Life Sciences Trading","version":"1.0","type":"link"}
