Custom Laboratory-Grade Quartz Screw Thread Bottles for Chemical Storage -TOQUARTZ®
Features of High Purity Quartz Screw Thread Bottle
Precision Threading
Each quartz sample storage bottle features precisely manufactured screw threads (GL14/GL18/GL25) that ensure secure sealing for sensitive chemicals. The thread specifications meet international laboratory standards, enabling compatibility with common laboratory closures and systems.
Chemical Resistance
Quartz screw thread bottles remain chemically inert when exposed to most acids, alkalis, and salt solutions. They maintain stability with virtually all chemicals except hydrofluoric acid, demonstrating 30 times the acid resistance of ceramics and 150 times that of stainless steel.
Thermal Stability
These high temperature quartz bottles maintain structural integrity and performance at temperatures up to 1200°C, with a softening point of 1730°C. The material's low thermal expansion coefficient (5.5×10⁻⁷/K) minimizes stress during rapid temperature changes, making these bottles ideal for high-temperature chemical reactions.
Optical Transparency
They provide excellent light transmission across the UV to IR spectrum, with visible light transmission exceeding 93%. This makes them ideal for photochemical experiments, UV sterilization applications, and optical testing where visual clarity is essential.

Usage Guidelines of Quartz Screw Thread Bottles
Proper handling, usage, and maintenance of quartz screw thread bottles ensure maximum performance and service life. Follow these guidelines to optimize the functionality and longevity of your TOQUARTZ® laboratory glassware.
Handling & Operation
- Avoid sudden temperature changes exceeding 150°C/minute to prevent thermal shock.
- When tightening caps, use moderate force to prevent thread damage. Hand-tight is sufficient.
- For high-temperature applications, use appropriate PTFE or quartz caps rather than standard caps.
- Always place bottles on heat-resistant surfaces when handling hot contents.
Cleaning & Maintenance
- Clean with mild detergent and rinse thoroughly with deionized water.
- For stubborn residues, soak in dilute acids (except HF) or bases as appropriate.
- Periodically inspect threads for damage and replace if necessary.
- Store in padded containers to prevent mechanical damage and extend service life.
Safety Precautions
- Always wear appropriate PPE when handling bottles containing hazardous materials.
- Ensure proper ventilation when storing volatile or hazardous chemicals.
- Never use bottles with visible cracks or damage.
- Follow your organization's guidelines for handling, storage, and disposal.
Storage Recommendations
- Store clean, dry bottles in a dust-free environment.
- Avoid physical impact or stacking heavy items on quartz bottles.
- Keep caps loosely fitted during storage to prevent thread seizing.
- For long-term storage, maintain controlled temperature and humidity conditions.

FAQ
Q: What makes quartz screw thread bottles superior to standard glass bottles?
A: Quartz screw thread bottles offer exceptional chemical resistance (30x better than ceramics), thermal stability (up to 1200°C), minimal thermal expansion, superior optical clarity, and high purity (99.99% SiO₂). These properties make them ideal for aggressive chemical storage, high-temperature applications, and sensitive analytical work where material compatibility is critical.
Q: What thread specifications are available for quartz bottles?
A: TOQUARTZ® Standard thread specifications include GL14, GL18, and GL25, which are compatible with common laboratory closure systems. Custom thread specifications can be manufactured according to specific requirements, including specialized dimensions, thread pitch, and sealing surfaces for high-pressure or vacuum applications.
Q: How do I clean quartz screw thread bottles properly?
A: For routine cleaning, use mild laboratory detergent and thorough rinsing with deionized water. For stubborn residues, soak in appropriate cleaning solutions (dilute acids or bases, except HF). Avoid abrasive cleaners that might scratch the surface. For high-purity applications, final cleaning with electronic-grade solvents and drying in a clean environment is recommended.
Q: Can quartz screw thread bottles be used for UV applications?
A: Yes, our high-purity quartz bottles provide excellent UV transmission, making them ideal for photochemical reactions, UV sterilization, and spectroscopic applications. The material transmits over 90% of UV radiation in the 200-400nm range, significantly outperforming standard borosilicate glass which blocks most UV wavelengths below 300nm.
Q: Are TOQUARTZ bottles suitable for autoclave sterilization?
A: Yes, quartz screw thread bottles can withstand standard autoclave conditions (121°C, 15-20 psi) without degradation. In fact, their thermal properties exceed autoclave requirements by a significant margin. When using in autoclaves, ensure caps are loosened to prevent pressure buildup, and allow bottles to cool gradually to room temperature to maximize service life.
