Centrifuge Tubes

<h2>What Are Centrifuge Tubes?</h2>
 Centrifuge tubes are cylindrical laboratory containers with caps that are used to separate, pellet, and store biological or chemical samples through centrifugal force. They are commonly made from polypropylene (PP) or polystyrene (PS) and are available in sizes ranging from small 0.5 mL microtubes to larger 50 mL conical tubes. These tubes are widely used for cell pelleting, protein precipitation, DNA and RNA extraction, tissue homogenate clarification, and long-term sample storage. Depending on the material, they can withstand temperatures from &minus;80 &deg;C to +121 &deg;C.
In short, the best centrifuge tube depends on your centrifuge rotor, required g-force, sample volume, and sterility needs.

<h2>How to Choose Centrifuge Tubes</h2>
 Volume and Rotor Compatibility
Select a tube size that matches both your sample volume and centrifuge rotor. Microtubes ranging from 0.5&ndash;2 mL are commonly used in microcentrifuges and can typically handle speeds up to 20,000 &times; g. Midi tubes in the 5&ndash;10 mL range are suitable for intermediate sample volumes, while 15 mL and 50 mL conical tubes are commonly used in clinical, research, and preparative centrifuges.
Material: Polypropylene vs. Polystyrene
Polypropylene (PP) tubes offer excellent chemical resistance and can tolerate temperatures from &minus;80 &deg;C to +121 &deg;C. They are suitable for autoclaving and exposure to many laboratory solvents. Polystyrene (PS) tubes provide superior optical clarity, making it easier to visually inspect samples and liquid levels, but they have lower resistance to solvents and extreme temperatures.
Sterility and Contamination Control
Sterile centrifuge tubes are typically gamma- or E-beam-irradiated and certified free of RNase, DNase, and pyrogens. These tubes are recommended for RNA extraction, cell culture, and clinical applications where contamination must be minimized. Non-sterile tubes may still be RNase- and DNase-free and are often suitable for routine DNA work and general sample storage.
Cap Design
Attached screw caps help prevent cap mix-ups and sample contamination, especially in high-throughput laboratories. Separate caps can be quicker to open and may be preferred in workflows that require frequent access to samples. If tubes will be used with automated systems, cap dimensions should be verified for compatibility with liquid handling equipment.
Packaging Options
Racked tubes provide convenient organization and allow direct pipetting while the tubes remain in the rack. Bulk-bagged tubes offer a more economical option for laboratories that process large volumes of samples and already have tube storage systems in place.
<h2> Comparing Common Centrifuge Tube Types</h2>
 Microtubes (0.5&ndash;2 mL) are ideal for PCR preparation, microcentrifuge applications, and storage of small sample volumes. They can generally withstand centrifugal forces up to 20,000 &times; g.
Midi tubes (5&ndash;10 mL) are designed for intermediate sample volumes such as culture supernatants and can typically tolerate forces up to 16,000 &times; g.
Sterile 15 mL conical tubes are frequently used for cell pelleting, RNA extraction, and clinical sample processing, with typical ratings between 12,000 and 15,000 &times; g.
Sterile 50 mL conical tubes are commonly selected for larger-volume applications including tissue culture work, density gradient preparation, and large-scale sample processing.
Polystyrene conical tubes in 15 mL and 50 mL formats are often chosen when visual sample inspection is important and solvent exposure is minimal.
<h2> Specifications and Features</h2>
 Polypropylene centrifuge tubes from Globe Scientific and Nest Scientific are manufactured from USP Class VI virgin resin and do not contain plasticizers or processing additives. Sterile products are typically irradiated to achieve a sterility assurance level (SAL) of 10⁻⁶. Most 15 mL tubes feature graduation marks at 1 mL intervals, while 50 mL tubes are usually graduated every 5 mL. MBP offers both bagged and racked centrifuge tube formats, including 15 mL and 50 mL conical tubes as well as smaller microtube and midi tube options.
MBP supports procurement departments by accepting purchase orders and offering institutional pricing for qualified high-volume customers. <a href="https://mbpinc.net/contact-us">Contact the MBP team today</a> for a customized quote.

<h2 data-section-id="1k6o3gy" data-start="0" data-end="50">What Are Midicentrifuge Tubes (5 mL and 10 mL)?</h2>
&nbsp;
Midicentrifuge tubes are polypropylene conical tubes available in 5 mL and 10 mL capacities, designed for laboratory workflows that require sample volumes larger than standard microtubes but smaller than traditional 15 mL conical tubes. These tubes provide an efficient solution for intermediate-volume applications and are commonly used in cell culture, protein purification, gradient fraction collection, virus concentration, and clinical specimen processing.
By filling the gap between 2 mL microcentrifuge tubes and 15 mL conical tubes, midi tubes help optimize sample handling and centrifugation efficiency while reducing unnecessary tube volume and excess headspace.
Midicentrifuge tubes are ideal for sample volumes between approximately 2 mL and 12 mL, especially when a 15 mL conical tube is too large for the application or incompatible with the available rotor setup.

&nbsp;
Selecting the Appropriate Volume
The choice between 5 mL and 10 mL tubes depends on the volume of your samples and workflow requirements.
5 mL midi tubes are well suited for applications involving smaller sample volumes, typically below 4.5 mL. They minimize excess headspace and can improve pellet formation during lower-speed centrifugation procedures.
10 mL midi tubes are commonly used for larger intermediate-volume applications, including culture supernatant collection, protein purification workflows, and virus concentration protocols requiring volumes between 6 mL and 10 mL.
Rotor Compatibility
Before purchasing midi tubes, verify that your centrifuge rotor or adapter system is designed to accommodate 5 mL or 10 mL formats. While many benchtop centrifuges support these tubes through dedicated adapters, compatibility varies by manufacturer and rotor model.
The standard dimensions of Globe Scientific 10 mL centrifuge tubes are compatible with many commonly used conical tube adapters found in research and clinical laboratories.
Sterility and Cap Design
Sterile midi tubes with attached screw caps are recommended for cell culture, clinical specimens, and applications where contamination control is essential. Attached caps also reduce the risk of sample mix-ups and accidental contamination.
Non-sterile tubes with separate caps may offer a more economical option for routine laboratory procedures where sterility is not required.
Packaging Considerations
Most midi tubes are supplied in bagged packaging rather than racks. A common configuration includes 100 tubes per bag, making them suitable for laboratories that process moderate to high sample volumes. Reviewing expected usage rates can help determine appropriate ordering quantities and inventory levels.

&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.
