Product Parameters

Key Features

• Thin Wall Precision (1.5mm) – Consistent thin wall construction with uniform thickness ensures precise fluid dynamics for micro-scale gas and liquid flow applications.
• 1100°C Heat Resistance – Maintains structural integrity at sustained high temperatures for laboratory heating, optical instrument protection and high-temperature fluid transport.
• HF & Strong Chemical Resistance – Superior to borosilicate glass tubing, withstands hydrofluoric acid and concentrated acids/alkalis for corrosive fluid transport and chemical processing.
• Smooth Inner & Outer Surfaces – Polished surfaces minimize flow resistance and particle adhesion, ensuring clean fluid transport and easy cleaning between uses.
• High Purity, No Contamination – 99.99% pure fused silica with zero impurity precipitation, preventing sample contamination in analytical and high-purity applications.

Applications

1. Micro Fluid Transport

Precision tubing for micro-scale gas and liquid flow circuits in analytical instruments and laboratory setups, with smooth inner walls ensuring laminar flow characteristics.

2. Laboratory Bubbler Tube

Miniature bubbling tube for gas-liquid reaction and reagent humidification in laboratory experiments, with chemical resistance allowing use with aggressive reagents.

3. Optical Instrument Sleeve

Light path sleeve and small light source protective tube for optical instruments, with high transmittance and heat resistance protecting sensitive components from thermal damage.

4. Analytical Equipment

Micro reaction vessel and sample holding tube for chemical analysis equipment, with inert quartz construction preventing interference with analytical results.

5. Coating Fixture Sleeve

Positioning sleeve for vacuum coating fixtures, with dimensional precision and heat resistance suitable for coating chamber environments.

Advantages over Borosilicate Glass

Unlike borosilicate glass tubes that are chemically attacked by HF and soften at elevated temperatures, this thin wall fused silica quartz tube offers full HF resistance, sustained 1100°C operation, and excellent thermal shock resistance to prevent cracking under rapid temperature cycling—making it the superior choice for micro-scale high-temperature, corrosive and high-purity fluid handling applications.
