Key Features
- High-Transparency Polypropylene — Crystal-clear PP formulation provides excellent sample visibility for pellet identification and volume verification without opening the tube.
- High-Speed Rated — Microcentrifuge tubes tested to 25,000 x g; 15 mL conical tubes rated to 12,000 x g; 50 mL conical tubes rated to 9,500 x g for reliable high-speed centrifugation.
- Leakproof Closure Systems — Secure snap-cap with audible closure confirmation (microcentrifuge tubes); screw-cap with silicone O-ring seal for leak-free containment during vortex mixing and inverted storage.
- DNase/RNase-Free Options — Certified free of detectable DNase, RNase, human DNA, and PCR inhibitors for sensitive molecular biology applications including PCR, qPCR, and NGS library preparation.
- Wide Temperature Range — Stable from -80°C (ultra-low temperature freezer storage) to +121°C (autoclaving); suitable for boiling, freezing, and autoclave sterilization cycles.
- Easy Sample Identification — Molded volume graduations in 0.1 mL increments (microcentrifuge) or 0.5 mL increments (conical) with a frosted writing area for permanent marking with solvent-resistant laboratory markers.
FAQ
What is the maximum RCF these tubes can withstand?
Microcentrifuge tubes (0.2-2.0 mL) are rated to 25,000 x g. 15 mL conical tubes are rated to 12,000 x g. 50 mL conical tubes are rated to 9,500 x g. These ratings assume proper tube loading (fill level ≥ 80% of nominal capacity) and use in a rotor with appropriate tube support. Always verify the maximum RCF for your specific rotor and tube combination before centrifugation.
Are these tubes suitable for PCR and molecular biology applications?
Yes. The DNase/RNase-free, pyrogen-free, and DNA LoBind variants are specifically manufactured and certified for PCR, qPCR, RT-PCR, and other molecular biology applications. Standard tubes may contain trace levels of nucleases or PCR inhibitors and are not recommended for sensitive molecular applications. Always select the certified molecular biology grade for PCR-based workflows.
Can the tubes be autoclaved for reuse?
Roundfin centrifuge tubes are labeled as single-use disposable. However, the polypropylene material is autoclavable at 121°C for 15 minutes. Repeated autoclaving may cause gradual loss of optical clarity and slight dimensional changes. For applications requiring reusable tubes, we recommend a maximum of 3-5 autoclave cycles before replacement. Never reuse tubes that have contained biohazardous or infectious materials.
What is the minimum order quantity?
Standard packaging ranges from 500 to 5000 tubes per case depending on tube size. Small evaluation orders of 1-2 cases are welcome. Institutional bulk pricing applies for orders of 50+ cases. OEM/ODM custom production with private-label packaging is available with minimum order quantities of 50,000-100,000 tubes depending on tube size and customization requirements.
