Product parameters

Product Name Quartz Tubes for Vacuum Sealing
Material High-Purity Fused Silica (Quartz Glass)
Key Features

  • Excellent thermal stability and high softening point, ideal for flame sealing under vacuum.

  • High chemical purity and inertness, ensuring no contamination of sealed samples.

  • Low gas permeability, maintaining vacuum integrity over time.

  • Robust construction; available with options like pre-formed constrictions (for easy sealing) and various end finishes.

  • Good optical clarity for sample observation (if required).
Applications

Specifically designed for creating an inert or vacuum environment for samples. Common uses include:

  • Sample Encapsulation: Sealing reactive materials, sensitive compounds, or high-purity substances under vacuum or inert gas for storage, transport, or further processing.

  • High-Temperature Reactions: Used as reaction vessels for experiments conducted under vacuum or controlled atmospheres at elevated temperatures.

  • Material Science Research: Encapsulating samples for annealing, crystal growth, or phase transition studies under specific atmospheric conditions.

  • Fabrication of Ampoules: Serving as a base material for creating custom quartz ampoules for specialized applications.
