Item Name:
Fused Quartz Tubing - 19mm x 2.75mm
SKU:
ABRQT230
Description:
This fused quartz tubing is manufactured from high-purity silica that is melted and drawn into a consistent, seamless tube with a heavy wall. The 19 mm outside diameter paired with a 3 mm wall thickness makes it a rigid, durable size that holds shape well during fabrication and resists deformation when heated. In scientific lampworking, fused quartz is chosen when the job demands extreme heat resistance, very low thermal expansion, and excellent chemical purity. It is commonly used for high-temperature process tubes, protective sleeves, and specialty components where standard glass materials are more likely to devitrify, sag, or fail under repeated thermal cycling. This size is especially useful when you need a stronger tube for structural sections, sleeves over internal parts, or applications where the tubing may be handled, clamped, or supported during use.
How it is used:
- Cut to length and fire-polish the ends for clean, chip-resistant edges before assembly
- Used as a high-temperature process tube or carrier tube in scientific and laboratory fabrication
- Used as a protective outer sleeve over internal components that need insulation from flame or radiant heat
- Worked with an oxy-hydrogen style flame when full forming and sealing operations are required due to quartz’s higher working temperature
- Incorporated into custom scientific builds where thermal shock resistance and purity are critical
Dimensions:
- Inner Diameter: 13.50mm
