Sorenson Centrifuge Tube 1.7 ml SafeSeal Pack of 250 Tubes

Sorenson SafeSeal Low-Retention Microcentrifuge Tubes - 1.7 mL, Siliconized Natural Polypropylene, Graduated, Flat Snap Cap, Certified Nuclease-Free (MPN: 11700)

The Sorenson BioScience 11700 (also cataloged as 11700-PK / 11700-CS) is a premium, molecular-biology-grade microcentrifuge tube engineered for workflows that demand maximum sample recovery and secure containment under extreme mechanical stress. Molded from high-clarity virgin polypropylene, these 1.7 mL tubes feature a specialized internal siliconized surface modification. This ultra-low-retention coating creates a highly hydrophobic inner matrix that prevents fragile DNA, RNA, proteins, and sticky chemical compounds from binding to the plastic walls. Equipped with an attached flat SafeSeal snap cap, the tube establishes an airtight mechanical lock that resists popping open during boiling water baths or high-speed centrifugation runs up to 30,000 x g.

Technical Performance and Design

• Premium Siliconized Surface Treatment: The interior walls undergo a specialized siliconization process to form an ultra-smooth, slick barrier. This low-retention architecture ensures near-zero sample hold-up, maximizing fluid recovery when pipetting expensive enzymes or rare genetic templates.

• Boil-Proof SafeSeal Mechanized Lock: Outfitted with an integrated flat snap cap featuring a reinforced positive-lock sealing rim. This design counters internal pressure buildup, guaranteeing the caps remain firmly sealed during high-temperature thermal cycler steps, boiling protocols, and deep-freeze cycles.

• High-Force Centrifugal Endurance: Built with structurally reinforced conical base walls designed to withstand extreme centrifugal forces up to 30,000 x g, making them fully compatible with heavy-duty microcentrifuge protocols and specialized pelleting lines.

• Certified Nuclease-Free Purity Profile: Manufactured under fully automated cleanroom conditions to ensure an aseptic, assay-ready state. Each batch is certified free of detectable RNase, DNase, human DNA, pyrogens, and PCR inhibitors right out of the bulk package.
