50mL Leak-Proof Centrifuge Tubes with Screw Caps

[High-Purity Material Durability]: These tubes are designed with longer screw caps featuring sealing rings, providing a leak-proof closure and preventing sample leakage. The smooth, flat inner surface minimizes residue, making them ideal a variety of laboratory applications. [Clear Marking and Easy Identification]: Each tube comes with a convenient white writing patch that resists matting, allowing clear and easy sample marking and identification. The large, unerasable frosted white printed area ensures that markings remain legible, even under harsh laboratory conditions. [Accurate and Easy-To-Read Graduations]: The tubes feature precise black graduations accurate to ±2%, with 1 mL increments up to 50 mL, allowing reliable measurement in scientific experiments. The easy-to-read scale and large writing space make these tubes suitable recording sample data directly on the tube. [Chemical and Temperature Resistance]: These centrifuge tubes are non-pyrogenic and DNase/RNase free, making them safe and ready use in sensitive biological applications. They are autoclavable at 121°C and freezable to -80°C, withstanding high pressures and providing versatility different laboratory procedures. [Wide Range of Laboratory Applications]: Ideal use in biochemistry and molecular biology, these tubes are widely used the separation and preparation of biological samples. Their high-quality material and precise design make them suitable high-speed centrifugation, sample collection, transportation, and more, catering to the diverse needs of scientific research and analysis.
