Frequently Asked Questions (Centrifuge Sourcing Guide)

Q1: How do I choose between a refrigerated centrifuge and a standard room-temperature model?

Refrigerated centrifuges are essential when processing temperature-sensitive biological samples such as enzymes, live cells, RNA, and proteins that degrade or denature at elevated temperatures generated during high-speed rotation. Standard room-temperature centrifuges are suitable for routine chemical and robust sample separations.

Q2: Are Qiwei centrifuge rotors interchangeable for different tube sizes?

Yes! Qiwei centrifuges support quick-exchange angle rotors and swing-out buckets compatible with diverse tube types, including micro-tubes (1.5ml/2.0ml), PCR strips, falcon tubes (15ml/50ml), and blood collection tubes.

Q3: Do you support OEM custom branding and wholesale distributor pricing?

Yes, as a factory-direct manufacturer, we offer complete OEM/ODM custom branding, customized UI panels, private label packaging, and tiered volume discounts for global laboratory equipment distributors.
