Complete Specifications
Aoxin Quartz offers the QTB15 Quartz Block, a specialized tool designed for the heat sealing of 20mm outer diameter quartz tubes. This precision-machined quartz block acts as a forming die, enabling a clean and reliable flame seal when preparing quartz ampoules or other sealed quartz vessels. Crafted from high-quality fused quartz, it offers excellent high-temperature resistance, non-stick properties, and durability for consistent sealing results. Its specific dimensions (15mm OD, 11mm Height) are optimized for working with 20mm OD quartz tubing.

Features
- Optimized for 20mm OD Tubes: Specifically designed and dimensioned to facilitate the effective heat sealing of quartz tubes with a 20mm outer diameter.
- High-Quality Quartz Material: Ensures superior performance at high flame-working temperatures without deforming or contaminating the tube being sealed.
- Clean and Uniform Seals: Helps to create a neat, consistent, and strong seal on quartz tubes, improving the reliability of ampoules or sealed vessels.
- Non-Stick Surface: Fused quartz offers good resistance to sticking when in contact with softened quartz, facilitating a clean release after sealing.
- Durable and Reusable: Designed for multiple sealing operations, providing a cost-effective tool for laboratory or production use (though wear is expected over time with high-temperature tools).
- Thermal Shock Resistant: Capable of withstanding the rapid temperature changes inherent in flame sealing processes.
- Precision Machined: Ensures accurate dimensions (15mm OD, 11mm Height) for repeatable sealing performance.
