Why do you need RNase-free, DNase-free centrifuge tubes for sensitive samples?
Off-the-shelf tubes often carry residual RNase/DNase or pyrogens, degrading RNA, qPCR signals, and cell cultures. Servicebio tubes are certified RNase/DNase- and pyrogen-free, so sensitive samples stay intact from first spin to −80°C storage.
What maximum RCF and temperature range can these centrifuge tubes handle?
1.5 / 2 mL tubes: up to 18,000 × g. 15 / 50 mL conical tubes: up to 17,500 × g. Rated −80°C to 121°C—freezer-safe and autoclavable, with a thickened PP wall that resists cracking at max RCF.
What are these RNase-free centrifuge tubes used for?
Built for PCR/qPCR and RNA/DNA work, sterile cell culture, −80°C sample storage, high-speed spins up to 18,000 × g, and sample homogenization with the dedicated grinding tube.
Are these centrifuge tubes really RNase/DNase-free, leak-proof, and crack-resistant?
Yes—independently certified. RNase/DNase-free prevents sample degradation; the screw cap seals leak-proof through inversion and freezing; the thickened PP wall survives 18,000 × g without cracking.
Where are these centrifuge tubes commonly used?
In molecular biology labs, sterile cell-culture suites, biobanks, and sample-prep pipelines. Buyers include university/hospital labs, IVD manufacturers, biopharma teams, and lab distributors.
What should you look for in a centrifuge tube supplier?
Verify four things: an ISO 13485:2016 quality system, CE/UKCA/TÜV compliance with MSDS per SKU, factory-direct supply with batch traceability, and OEM/ODM support for custom logos and packaging.
Which centrifuge tube volume should I choose?
1.5 / 2 mL for PCR and grinding; 15 mL for cell culture and routine spins; 50 mL for large volumes and biobanking. All share the same nuclease-free rating and −80°C–121°C range. Available in bulk bag, rack, or sterile wrap.
