Material Composition
Quartz Test Tube
Quartz test tubes are crafted from high-purity fused quartz glass (>99.9% SiO₂), ensuring exceptional chemical inertness and thermal stability3. The material undergoes precision processing (e.g., melting, stretching) to achieve uniform wall thickness and optical clarity3.
Key Features
- Extreme Temperature Resistance: Operates reliably at up to 1200°C without deformation or degradation34.
- Chemical Inertness: Resists corrosion from acids, alkalis, and organic solvents, ideal for reactive substance handling34.
- Ultra-Low Thermal Expansion: Maintains structural integrity under rapid temperature fluctuations (coefficient: 5.5×10⁻⁷/°C)3.
- Optical Transparency: Transmits UV to infrared wavelengths (190–2500nm), enabling spectroscopic analysis36.
Applications
| Industry | Use Cases |
|---|---|
| Laboratory R&D | High-purity chemical synthesis, catalyst testing, and sample containment34. |
| Semiconductor | Wafer cleaning, etching, and ultra-pure reagent storage in chip fabrication36. |
| Medical | Sterilization of lab equipment, drug development, and bio-sample preservation46. |
| Environmental | Air/water quality monitoring and hazardous waste analysis36. |
Customization Options
- Sizes: Diameter 8–50mm, length 100–500mm (standard); bespoke dimensions available3.
- Surface Treatments: Opaque or transparent variants for controlled light transmission3.
- Certifications: Compliant with ISO9001, RoHS, and medical-grade standards46.
Advantages Over Competitors
- Durability: 5,000+ hours of continuous use in corrosive environments36.
- Energy Efficiency: Reduces heat loss by 30% compared to borosilicate alternatives34.
- Hygienic Design: Non-porous surface prevents microbial growth, critical for sterile workflows46.
