Extreme Temperature & Thermal Shock Resistance
Manufactured from high-purity quartz, these conduits can withstand continuous operating temperatures up to 1200°C and possess exceptional resistance to thermal shock, making them ideal for rapid heating and cooling cycles in demanding high-temperature processes.
Unparalleled Chemical Inertness
Offering superior resistance to almost all acids and alkalis, quartz laboratory tubing ensures minimal interaction with corrosive chemicals. This prevents contamination of sensitive samples and extends the lifespan of the tubing in harsh chemical environments.
High Purity & Optical Transparency
With a silicon dioxide purity of ≥99.99%, these conduits maintain the integrity of ultra-pure fluids and gases. Their high light transmittance allows for clear visual monitoring of flow and is beneficial for applications involving UV light, such as photocatalysis or spectroscopy.
Versatile Customization & Robust Construction
Capable of being precisely fabricated into various complex shapes (e.g., L-bends, T-connections, multi-branch designs) with firmly welded joints and rounded tube mouths, these tubes offer unmatched flexibility for custom laboratory setups and industrial systems, ensuring durable and leak-proof connections.
Application Scenario
High-Temperature Fluid and Gas Transfer Systems
Essential for conveying hot gases or liquids in high-temperature furnaces, reactors, or heating systems, where conventional glass or metal tubing would deform or corrode due to extreme heat.
Corrosive Chemical Transport
Utilized in laboratories and industrial processes for the safe and inert transfer of highly corrosive acids, alkalis, or aggressive solvents, preventing material degradation and ensuring the purity of the conveyed substances.
High-Purity Gas/Liquid Delivery for Sensitive Processes
Crucial in industries like semiconductor manufacturing, pharmaceutical production, or analytical chemistry, where ultra-high purity requirements dictate that the conduit material itself does not leach impurities into the gas or liquid stream.
Custom Laboratory Apparatus and Manifolds
Employed in specialized research setups for constructing complex gas or fluid manifolds, reaction pathways, or custom distillation/evaporation systems, leveraging the ability to precisely fabricate various bends, tees, and custom configurations.
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 laboratory conduits are highly versatile. They can be connected to other quartz or glass components using standard ground glass joints, secured with clamps and potentially vacuum grease for leak-tight seals. For permanent or robust connections, they can be directly fused (welded) together, or integrated into systems using specialized high-temperature fittings, silicone tubing, or compression fittings, depending on the application and desired seal integrity.
Yes, quartz laboratory conduits can be heated directly with a flame and are excellent for applications involving rapid heating and cooling. Due to quartz’s extremely low coefficient of thermal expansion, they exhibit superior resistance to thermal shock compared to other glass types, allowing them to withstand significant and abrupt temperature changes without cracking or breaking.
While highly inert, quartz laboratory tubing does have limitations. It is generally not recommended for prolonged exposure to hydrofluoric acid (HF) at any concentration, or hot concentrated phosphoric acid, as these can etch and degrade the quartz. Additionally, strong bases (alkalis) at elevated temperatures can also cause some etching over extended periods. For most other common acids, bases, and organic solvents, quartz provides excellent resistance.
