Fisherbrand Centrifuge Tube 2 mL Snap Cap - 1500 tubes (3 cases)

Fisherbrand 14-666-314 Microcentrifuge Tubes – 2.0 mL, Locking Snap Cap, Assorted Colors

The Fisherbrand 14-666-314 is a specialized 2.0 mL microcentrifuge tube designed for labs requiring high-security sample containment and easy color-coded organization. These tubes feature a unique locking snap-cap mechanism that provides a superior mechanical seal compared to standard friction-fit caps, ensuring they remain closed during high-speed centrifugation, vigorous vortexing, and thermal incubation. Manufactured from high-clarity, medical-grade polypropylene, this assorted pack includes a variety of vibrant colors (Blue, Green, Red, Yellow, and Natural), allowing for rapid visual differentiation of samples or experimental groups. Certified DNase, RNase, and pyrogen-free, the 14-666-314 is a reliable choice for genomic research, clinical diagnostics, and high-purity protein applications.

Technical Performance and Design

• Locking Snap-Cap Mechanism: Specifically engineered to "click" into a locked position, providing extra security against pop-opens during boiling water baths or high-force centrifugation.

• Assorted Color-Coding: Supplied in a mix of colors to help organize complex workflows, distinguish between reagents and patients, or identify different stages of a protocol at a glance.

• High RCF Rating: Designed with reinforced walls to withstand centrifugation forces up to 25,000 x g, making them suitable for heavy-duty pelleting and nucleic acid precipitation.

• Easy-to-Read Graduations: Features molded-in volume increments for quick and accurate estimation of sample volumes during liquid handling steps.

Key Benefits & Applications

• High-Throughput Sample Tracking: The multi-color format is ideal for labs running large-scale comparative studies where quick visual identification is critical to preventing errors.

• Boiling and Incubation: The locking cap is the preferred choice for protocols involving heat-induced epitope retrieval or DNA denaturation, where standard tubes might pop open due to internal pressure.

• Secure Long-Term Storage: Provides a reliable seal for maintaining the integrity of samples in temperatures as low as -86°C, reducing the risk of sample desiccation.

• Shatterproof Durability: The medical-grade resin is designed to remain flexible and crack-resistant even when subjected to extreme thermal and mechanical stresses.
