Exceptional High-Temperature & Chemical Resistance
Crafted from high-purity quartz glass, these tubes can withstand extreme temperatures up to 1200°C and exhibit superior inertness to a wide range of corrosive acids and alkalis, ensuring stability and longevity in harsh reaction environments.
Superior Purity & Non-Contaminating
With a silicon dioxide purity of ≥99.99%, quartz Schlenk tubes prevent leachables and minimize contamination of sensitive reactants or products, making them ideal for high-purity chemical synthesis and analytical applications.
Optimized for Air-Sensitive & Vacuum Chemistry
Designed specifically for handling air-sensitive compounds, these tubes feature precision ground joints and integrated stopcocks for efficient evacuation and backfilling with inert gas, enabling robust and reliable operations under vacuum or controlled atmospheres.
High Optical Transmittance & Customizable Design
Offering high light transmittance (≥90%), they are perfect for photochemical reactions. Furthermore, their “Full Specs: Custom” capability allows for tailored dimensions, capacities, and specialized configurations to meet unique experimental and industrial requirements.
Application Scenario
Air-Sensitive Chemical Synthesis & Manipulation
Indispensable for handling and reacting compounds that are sensitive to air or moisture, such as organometallics, catalysts, or highly reactive intermediates. The integrated stopcock and ground joints allow for operations under strict inert gas or vacuum conditions.
High-Temperature Reactions under Controlled Atmosphere
Used for chemical reactions, material synthesis, or pyrolysis processes that require both elevated temperatures (up to 1200°C) and a precise, oxygen-free, or specific gas environment, which traditional glassware cannot withstand.
Vacuum Line Operations & Gas Manifold Systems
Integral components in vacuum distillation, sublimation, or gas transfer setups where maintaining high vacuum or controlled gas flow is critical. Their robust design and precise joints ensure leak-tight connections for efficient and safe operations.
Photochemistry & Spectroscopy with Corrosive Reagents
Due to quartz’s high UV transparency and chemical inertness, these tubes are ideal for photochemical reactions where UV light needs to pass through the reaction mixture, or for preparing samples for spectroscopic analysis involving corrosive solvents.
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.
The primary advantage lies in quartz’s superior material properties. Quartz Schlenk tubes can withstand significantly higher temperatures (up to 1200°C compared to around 500°C for borosilicate), offer far better chemical inertness to a wider range of aggressive chemicals, and provide excellent optical transmission, especially in the UV spectrum, which is crucial for photochemical reactions. This makes them indispensable for more extreme and sensitive applications.
Yes, quartz Schlenk tubes are designed with precision ground joints and robust construction to handle high vacuum applications effectively, ensuring a tight seal for air-sensitive chemistry. While they are durable, their use under high pressure should be considered based on the specific wall thickness and design; custom solutions are often recommended for elevated pressure requirements. Always consult specifications or contact us for high-pressure applications.
To ensure a proper, leak-free seal, first ensure both the ground joint on the tube and the corresponding joint are clean and free of particles. Apply a thin, even layer of high-vacuum grease (unless grease-free operation is required, then use appropriate O-rings/clips for specific joint types) to the top half of the inner joint, then insert and rotate the outer joint to spread the grease evenly, creating a transparent seal. Secure with appropriate clamps or clips if necessary, especially under vacuum.
