Polypropylene (PP) models (63401, 63402) offer excellent chemical resistance to a wide range of reagents, full autoclavability at 121°C without degradation, and good clarity suitable for most applications. They are the best choice for routine use and applications requiring repeated sterilization.
Polycarbonate (PC) models (63411, 63412) provide exceptional optical clarity approaching that of glass, making them the top rated choice when maximum visibility of contents and pellets is critical. However, repeated autoclaving reduces their mechanical strength over time, so they are best suited for single-use or limited autoclave cycles.
Both materials are strong enough for use up to 50,000xG.
Both polypropylene and polycarbonate models are strong enough to be used up to 50,000xG, making them suitable for the most demanding high-speed centrifugation and ultracentrifugation applications. This rating applies when tubes are used according to manufacturer guidelines and with appropriate rotors and adapters.
Yes, these tubes can be autoclaved. However, there is an important distinction: Polypropylene (PP) tubes can be repeatedly autoclaved at 121°C without significant degradation, maintaining their mechanical strength. Polycarbonate (PC) tubes can also be autoclaved, but repeated autoclaving progressively reduces their mechanical strength. For PC tubes, we recommend single-use or limited autoclave cycles for applications requiring maximum strength.
Four tube models are available:
• Code 63401: 16ml polypropylene (PP)
• Code 63402: 50ml polypropylene (PP)
• Code 63411: 16ml polycarbonate (PC)
• Code 63412: 50ml polycarbonate (PC)
All models are supplied in packs of 50 pieces.
Yes, replacement caps are available separately:
• Code 63421: Caps for 16ml tubes, supplied in packs of 100 pieces
• Code 63422: Caps for 50ml tubes, supplied in packs of 100 pieces
This allows you to replace lost or damaged caps and extend the useful life of your tubes.
The round bottom design offers several advantages for certain applications: it facilitates complete resuspension of pellets without the dead space found in conical tubes; it is preferred for certain rotor types, particularly swinging-bucket rotors; and it is ideal for density gradient centrifugation where undisturbed layers are important. The smooth interior surface also minimizes sample retention.
All tube models (63401, 63402, 63411, 63412) are supplied in packs of 50 pieces. Cap models are supplied in packs of 100 pieces: 63421 for 16ml caps, 63422 for 50ml caps. These economical pack quantities ensure adequate supply while maintaining cost efficiency.
Polypropylene offers excellent resistance to a wide range of chemicals including aqueous solutions, dilute acids and bases, alcohols, and many organic solvents. Polycarbonate has good resistance to many reagents but can be affected by strong bases, some organic solvents, and prolonged autoclaving. For specific chemical compatibility with your samples, consult standard resistance charts for each material.
Yes, with a maximum rating of 50,000xG, these tubes are suitable for many ultracentrifugation applications. However, always verify compatibility with your specific rotor and centrifuge model, and never exceed the manufacturer recommended G-force for your specific tube and rotor combination. Proper tube filling and balancing are essential for safe ultracentrifugation.
These round bottom centrifuge tubes combine multiple features that make them exceptional: dual material options (PP and PC) allow selection for specific application needs; 50,000xG strength handles the most demanding protocols; excellent clarity in both materials enables sample visualization; round bottom design facilitates pellet resuspension; autoclavable construction (with material-specific considerations) allows sterilization; replacement caps extend tube life; and economical 50-piece packs provide excellent value. This comprehensive range, focused on real high-speed centrifugation needs, makes these tubes the best choice and the top rated solution for demanding applications.
