Exceptional High-Temperature and Chemical Resistance
Crafted from high-purity quartz, these connectors can withstand extreme temperatures (far exceeding borosilicate glass) and exhibit superior inertness to most acids and alkalis, making them ideal for reactions and processes in harsh chemical and thermal environments.
High Purity and Non-Contaminating
Made from ultra-high purity fused silica, these connectors guarantee minimal leaching or contamination. This characteristic is vital for sensitive analytical procedures, high-purity material synthesis, and any application where sample integrity is paramount.
Secure, Leak-Tight Sealing
The precision-ground conical joints ensure a tight, reliable, and leak-free connection between various glassware components. This is crucial for maintaining vacuum, controlling atmospheres, or preventing loss of volatile chemicals in demanding laboratory and industrial setups.
Robust Durability and Versatility
Quartz is known for its strength and resistance to thermal shock, providing excellent durability and a long service life. Available in standard ground joint sizes and supporting custom designs, these connectors offer versatile solutions for complex plumbing of high-performance glassware systems.
Application Scenario
High-Temperature Reaction Apparatus Assembly
Used to securely connect various components (e.g., flasks, condensers, thermometers) in chemical reaction setups that operate at extremely high temperatures, where conventional glass connectors would soften or degrade.
Corrosive Chemical Transfer & System Integration
Essential for building leak-proof systems and transfer lines for highly corrosive acids, alkalis, or reactive gases. The exceptional chemical inertness of quartz ensures the integrity of the fluid path and prevents material degradation.
High Vacuum & Inert Atmosphere Systems
Critical for creating and maintaining ultra-high vacuum environments or sealed systems under inert gas (like argon or nitrogen), typically found in air-sensitive chemistry, glovebox setups, or thin-film deposition equipment, ensuring minimal leakage.
High-Purity Material Processing & Analytical Sample Preparation
Employed in applications requiring the utmost purity, such as semiconductor processing, trace element analysis, or pharmaceutical synthesis, where these connectors prevent contamination and maintain the integrity of high-purity chemicals or samples.
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.
Yes, our quartz connectors are manufactured to adhere to international standards for conical ground joint sizes (e.g., 14/20, 24/40). This ensures full compatibility and interchangeability with borosilicate glassware and other laboratory apparatus that utilize standard taper ground joints of the corresponding size.
For optimal vacuum-tight sealing, ensure both male and female ground joints are perfectly clean and dry before assembly. Apply a thin, even layer of high-vacuum grease to the top half of the inner joint. Insert the outer joint and rotate gently to spread the grease uniformly, creating a clear, bubble-free seal. For systems requiring grease-free operation, specialized O-rings or PTFE sleeves compatible with the ground joint can be used.
You should choose a quartz connector when your application involves extremely high temperatures (above 500°C), highly corrosive chemicals (where borosilicate might degrade), or requires the absolute highest purity with no leaching from the glassware. Quartz’s superior thermal shock resistance and chemical inertness make it indispensable for demanding scientific and industrial processes.
