1. Ultra-High Purity – Never Contaminates Contents

• SiO₂ purity ≥ 99.99%, premium grades up to 99.999%
• Extremely low metal ion content — no precipitation or dissolution
• Introduces no impurities when storing high-purity reagents and chemicals
• The standard container for semiconductor-grade chemical storage

2. Strong Corrosion Resistance – Superior Chemical Inertness

• Resists most strong acids (except hydrofluoric acid) and strong oxidizers
• Resists weak alkalis; no reaction with contents at high temperatures
• Safely stores aqua regia, concentrated sulfuric acid, nitric acid and other highly corrosive media
• Service life far exceeds glass and plastic containers

3. Extreme Heat Resistance – Heatable & Autoclavable

• Long-term service temperature 1100°C–1200°C
• Can be heated directly, baked at high temperatures and autoclaved
• Suitable for distillation, digestion, high-temperature reactions and other processes
• Ordinary glass bottles shatter when heated; quartz bottles remain stable at high temperatures

4. Thermal Shock Resistant – Safe & Durable

• Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C)
• No cracking or fracturing under drastic temperature changes
• Can be cooled immediately after heating — safe and worry-free operation

5. Full-Spectrum Transmission – Visible & Measurable

• High transmittance across the full UV-to-IR spectrum
• Liquid level and reaction progress inside the bottle are clearly visible
• Supports UV transmission, irradiation and optical inspection

6. Excellent Sealing – Prevents Evaporation & Contamination

• Optional quartz / PTFE sealing caps provide excellent sealing performance
• Effectively prevents evaporation, moisture absorption and contamination of high-purity liquids
• Contents remain compositionally stable during long-term storage

7. Complete Size Range – Deep Customization

• Types: wide-mouth bottle, narrow-mouth bottle, flask, round-bottom flask, reaction bottle
• Capacity: 10ml – 20L (larger sizes available on request)
• Wall thickness: uniform and controllable; thickened pressure-rated designs supported
• Processing: ground mouths, flanged mouths, graduation lines, fired markings
• Accessories: quartz caps, ground stoppers, PTFE seals
