Custom quartz ampoules are precision-fabricated sealed or sealable containers made from high-purity fused quartz (SiO₂), widely used in materials synthesis, crystal growth, chemical reactions, vacuum sealing, and high-temperature processing. Quartz ampoules offer exceptional thermal stability, chemical inertness, low impurity content, and optical transparency, making them ideal for demanding laboratory and industrial environments.

Compared with borosilicate or standard glass, quartz ampoules can withstand significantly higher temperatures, rapid thermal cycling, and aggressive chemical conditions without deformation or contamination. Their ultra-low metal impurity levels ensure minimal interaction with sensitive samples, which is critical for semiconductor materials, chalcogenides, halides, perovskites, and specialty compounds.

We provide fully custom quartz ampoules tailored to your experimental or production requirements. Dimensions, wall thickness, end geometry, sealing method, and surface finish can all be customized. Options include one-end sealed, two-end open, pinch-off tips, necked designs, and vacuum-ready geometries, suitable for flame sealing or pump–seal processes.

Our quartz ampoules are manufactured with strict dimensional control and clean fabrication processes, ensuring consistent quality for university research, national laboratories, and OEM customers.

Frequently Asked Questions — Custom Quartz Ampoules

What is a quartz ampoule used for?
Quartz ampoules are used for sealed or sealable containment of materials during high-temperature processing, chemical synthesis, crystal growth, vacuum reactions, and long-term storage of sensitive compounds.
Why use quartz instead of borosilicate or standard glass?
Fused quartz offers much higher temperature resistance, superior chemical inertness, lower impurity levels, and better thermal shock resistance compared with borosilicate or standard glass, making it ideal for demanding laboratory and industrial applications.
What temperatures can quartz ampoules withstand?
Quartz ampoules can typically withstand continuous operation above 1000 °C and short-term exposure to even higher temperatures, depending on wall thickness, geometry, and heating conditions.
Can the ampoules be vacuum sealed?
Yes. Quartz ampoules can be supplied with geometries suitable for flame sealing, pump-and-seal processes, pinch-off tips, and vacuum-ready neck designs.
What dimensions and geometries are available?
Fully custom dimensions are available, including length, inner/outer diameter, wall thickness, and end geometry. Options include one-end sealed, two-end open, necked designs, and special shapes for specific experimental setups.
Are quartz ampoules suitable for sensitive materials?
Yes. High-purity fused quartz has very low metal impurity content and low outgassing, making it suitable for semiconductor materials, chalcogenides, halides, perovskites, and other sensitive compounds.
Do you support research and OEM production?
Absolutely. Our custom quartz ampoules are supplied to universities, national laboratories, and OEM customers for both small-scale research and production-oriented applications.
