FAQ
Q1: Can quartz test tubes be used with hydrofluoric acid (HF)?
No, quartz reacts violently with HF. Use PTFE or carbon tubes instead.
Q2: How do I clean quartz tubes?
Use dilute acids (e.g., HNO₃/HCl) or specialized quartz cleaners; avoid abrasive scrubbing.
Q3: Are these tubes reusable?
Yes, with proper cleaning, they can be reused multiple times.
Q4: What's the lead time for custom sizes?
It depends on order quantity and craftsmanship.
Q5: Do you provide certifications?
Yes, material purity reports (e.g., 99.99% SiO₂) and ISO compliance available upon request.
