FAQ
Q1: Can it be used with hydrofluoric acid (HF)?
A: No, quartz reacts with HF. Use Teflon or platinum crucibles instead.
Q2: Are custom sizes available?
A: Yes, we provide tailored dimensions, wall thicknesses, and shapes.
Q3: What's the lead time for bulk orders?
A: Usually within 7 days, depending on quantity and customization.
