15ml & 50ml Centrifuge Tubes

<h2 data-section-id="155qizo" data-start="0" data-end="33">What Are All Centrifuge Tubes?</h2>
&nbsp;
The All Centrifuge Tubes collection includes the complete range of tube sizes commonly used in research, clinical, and laboratory environments. These tubes range from small 0.5 mL and 1.5&ndash;2 mL microtubes used in microcentrifuge applications to 5 mL and 10 mL midi tubes for intermediate sample volumes, as well as 15 mL and 50 mL conical tubes designed for cell culture, density gradient preparation, and larger-volume sample processing. They are available in polypropylene (PP) for enhanced chemical resistance and temperature tolerance or polystyrene (PS) for improved optical clarity.

<h2 data-section-id="1f93yys" data-start="914" data-end="963">How to Choose From All Centrifuge Tube Formats</h2>
&nbsp;
Volume and Rotor Compatibility
Selecting the correct tube size is essential for safe and efficient centrifugation. Microtubes ranging from 0.5&ndash;2 mL are designed for microcentrifuges, while 5&ndash;10 mL midi tubes fit compatible benchtop centrifuge rotors. Larger 15 mL and 50 mL conical tubes are commonly used in clinical and research centrifuges. Always verify rotor compatibility before introducing a new tube format into your workflow.
Sterility Requirements
For sensitive applications such as RNA extraction, cell culture, and clinical diagnostics, sterile tubes certified free of RNase, DNase, and pyrogens are recommended. Non-sterile tubes can provide a cost-effective solution for routine DNA analysis, protein assays, and general sample storage where sterility is not critical.
Material Selection
Polypropylene tubes offer excellent durability, can be autoclaved at 121 &deg;C, and resist many laboratory chemicals and solvents. Polystyrene tubes provide superior transparency, making it easier to monitor liquid levels and sample contents, although they are less resistant to heat and solvents.
Packaging and Inventory Planning
Microtubes are commonly available in pack sizes ranging from 500 to 1,000 units, while 15 mL and 50 mL conical tubes are often supplied in cases of 500. Laboratories with consistent usage may benefit from establishing recurring purchase orders to ensure uninterrupted supply.

<h2 data-section-id="urfo3f" data-start="2395" data-end="2433">Compare Centrifuge Tube Size Groups</h2>
&nbsp;
Microtubes (0.5&ndash;2 mL) are primarily used for PCR preparation, microcentrifuge applications, and storage of small sample volumes. These are typically manufactured from polypropylene and are available in pack sizes of 500&ndash;1,000 units.
Midi tubes (5&ndash;10 mL) support intermediate-volume centrifugation and supernatant collection. They are commonly made from polypropylene and supplied in packs ranging from 100&ndash;500 units.
15 mL conical tubes are widely used for cell pelleting, RNA isolation, and clinical sample processing. They are available in both polypropylene and polystyrene formats and are generally packaged in cases of 500.
50 mL conical tubes are designed for larger-volume workflows, including tissue culture, density gradient preparation, and sample processing. Like 15 mL tubes, they are available in polypropylene and polystyrene and are commonly sold in cases of 500.

<h2 data-section-id="1ezckh3" data-start="3318" data-end="3348">Specifications and Features</h2>
&nbsp;
Globe Scientific and Nest Scientific centrifuge tubes are manufactured from USP Class VI virgin polypropylene or polystyrene resin and are certified free from detectable RNase, DNase, and pyrogens. Sterile products are irradiated using gamma or E-beam methods to achieve a sterility assurance level (SAL) of 10⁻⁶. MBP offers both racked and bagged formats for 15 mL and 50 mL conical tubes, along with dispenser-box options for selected microtube product lines that support efficient use in high-throughput laboratory environments.
For procurement teams, MBP accepts purchase orders and offers institutional pricing for bulk and high-volume purchases. <a href="https://mbpinc.net/contact-ushttps://mbpinc.net/contact-us" title="Contact the MBP team" style="color: #236fa1;">Contact the MBP team</a> today to learn more
