## Questions & Answers

**Q: Are Cobetter centrifuge filters reusable?**
A: We recommend using them once, but some of our customers tried to use it for the same sample up to maximum 3 times, only for reference only.

**Q: How to clean Cobetter centrifuge filters?**
A: First, soak them in 0.1M NaOH for 24 hours, then soak them in 20% ethanol for preservation.

**Q: Can Cobetter centrifuge filters be used to filtrate exosomes?**
A: Yes, and it is recommended to use 100kDa first and then 3kDa centrifuge filters to concentrate exosomes with serum, and 3kDa centrifuge filters can be used directly for those without serum.

**Q: Are Cobetter centrifuge filters compatible with regular centrifuges?**
A: No, they aren't. They are matched to conical bottom centrifuges.

**Q: What is the size of the outer tubes?**
A: The outer tubes for 4ml centrifuge filters is 15ml, and the outer tubes for 15ml centrifuge filters is 50ml.
