Exceptional Thermal Shock Resistance
Beyond their high maximum operating temperature of 1200°C, these quartz flasks exhibit superior resistance to thermal shock, allowing for rapid heating and cooling cycles without the risk of cracking or deformation, crucial for dynamic reactions.
Broad Chemical Compatibility & Non-Reactive Surface
The inherently inert nature of quartz glass provides outstanding resistance to a wide range of corrosive chemicals, preventing leaching and unwanted side reactions, thus guaranteeing the purity and yield of your experimental results.
Flawless Optical Clarity for Precision Monitoring
With high light transmittance and a solid, bubble-free weld, these flasks offer crystal-clear visibility into your reaction, enabling precise visual monitoring of phase changes, color shifts, and other critical reaction parameters throughout the process.
Unrivaled Purity for Sensitive Reactions
Manufactured from 99.99% high-purity SiO2, our quartz flasks ensure minimal contamination, making them ideal for ultra-pure chemical processes, pharmaceutical synthesis, and sensitive analytical applications where material integrity is paramount.
Application Scenario
High-Temperature Chemical Synthesis & Reactions
These flasks are indispensable for organic and inorganic synthesis requiring elevated temperatures (up to 1200°C) that conventional borosilicate glass cannot withstand, such as specific material development, catalyst testing, or high-boiling point distillations.
Corrosive Chemical Processing
Due to quartz’s exceptional inertness and resistance to most acids and alkalis, these flasks are ideal for safely handling aggressive or highly corrosive chemicals, including strong acids (excluding HF and hot phosphoric acid) and harsh industrial solvents, preventing vessel degradation and sample contamination.
High-Purity Material Production & Analysis
In industries like pharmaceuticals, semiconductors, and advanced materials, where even trace contamination is critical, the 99.99% high-purity SiO2 construction ensures the integrity and purity of sensitive chemical processes, crystal growth, or ultra-pure substance synthesis.
Vacuum or Pressure Reactions & Distillations
The robust and precisely engineered ground glass joints, combined with the structural integrity of fused silica, make these multi-neck flasks suitable for complex vacuum distillations, inert atmosphere reactions, or controlled pressure experiments where gas tight seals and thermal stability are crucial.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Quartz three-neck flasks offer significantly higher heat resistance (up to 1200°C stable operating temperature compared to borosilicate’s ~500°C), superior chemical inertness to a wider range of acids and alkalis, and exceptional purity (SiO2 ≥99.99%) which minimizes contamination in sensitive reactions. They also exhibit better thermal shock resistance and optical clarity for visual monitoring at extreme conditions.
Yes, absolutely. We offer full customization for our quartz three-neck flasks. This includes custom dimensions (bottle height, diameter), various neck sizes and angles, different bottleneck selections, and multi-shape options to perfectly match your unique experimental setup or industrial process requirements. Please contact our customer service with your specific specifications.
While highly resistant to most acids and alkalis, quartz glass is generally not recommended for prolonged exposure to hydrofluoric acid (HF) at any concentration, or hot concentrated phosphoric acid. These specific chemicals can etch or degrade the quartz material over time. For all other common laboratory chemicals, including strong acids and bases (within the material’s temperature limits), quartz offers excellent resistance.
