Unrivaled High-Temperature & Thermal Shock Resistance
Crafted from fused quartz, these flasks can withstand continuous temperatures up to 1200°C and tolerate rapid temperature changes without cracking. This makes them ideal for demanding applications like high-temperature reflux, distillation, and direct heating on hot plates, where standard glassware would fail.
Exceptional Purity and Chemical Inertness
The ultra-high purity (>99.99% SiO₂) of the quartz material ensures that no contaminants leach into your sensitive samples, which is critical for trace analysis, semiconductor processing, and high-purity chemical synthesis. It also exhibits superior resistance to nearly all acids (except HF) and bases, preventing corrosion and ensuring the integrity of your reagents.
Secure & Versatile Standard Taper Ground Joints
Each flask features a precision-ground standard taper joint, ensuring a tight, leak-proof seal with other standard laboratory components such as condensers, stoppers, and adapters. This facilitates the easy and secure assembly of complex distillation, reflux, or vacuum setups, enhancing experimental efficiency and safety.
Accurate Graduations & Stable Design
Equipped with clear, easy-to-read volume graduations, these flasks allow for precise liquid measurement. The robust, flat base provides excellent stability on laboratory benchtops and hot plates, minimizing the risk of accidental spills and ensuring consistent heating and stirring during your experimental procedures.
Application Scenario
High-Temperature Chemical Synthesis & Reflux
Ideal for organic and inorganic synthesis reactions that require prolonged heating or operate at elevated temperatures where standard borosilicate glass might deform or fail. The quartz flask’s superior thermal resistance and thermal shock capabilities ensure safe and stable reflux conditions, crucial for achieving desired reaction yields and kinetics.
Trace Analysis & Ultra-High Purity Sample Preparation
In fields like environmental monitoring, pharmacology, or semiconductor analysis, even minute contaminants can compromise results. These flasks are used for preparing and storing samples for sensitive techniques (e.g., ICP-MS, AAS) as their ultra-high purity fused quartz prevents the leaching of metal ions or other impurities, ensuring the integrity and accuracy of your analytical data.
Handling Aggressive & Corrosive Chemicals
For reactions involving concentrated acids (except hydrofluoric acid), strong bases, or other highly corrosive reagents, quartz flasks offer exceptional chemical inertness. This resistance prevents degradation of the flask over time and ensures that the vessel itself does not react with or contaminate the chemical contents, providing a safer and more reliable reaction environment.
Vacuum Distillation & Filtration Setups
The precision standard taper ground joint allows for seamless and airtight connection to other vacuum apparatus, such as vacuum pumps, condensers, or receiving flasks. This makes them perfect for vacuum distillation processes to separate volatile compounds at lower temperatures, or for vacuum filtration setups where a robust, chemically resistant flask is required to collect filtrates under reduced pressure.
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, absolutely. Our quartz Erlenmeyer flasks are manufactured with precision standard taper ground joints (e.g., 24/40, 19/22, etc.). This ensures universal compatibility with a wide array of existing standard taper glassware, including condensers, stoppers, adapters, and distillation setups. This allows for seamless integration into your current laboratory apparatus without requiring specialized connectors.
To maintain the exceptional purity and clarity of these quartz flasks, it’s best to rinse thoroughly with deionized (DI) or ultra-pure water after use. For stubborn residues, a mild, lab-grade detergent and a soft brush or sponge are recommended. For highly sensitive applications or trace analysis, a soak in a dilute acid solution (e.g., nitric acid, avoiding hydrofluoric acid) followed by extensive rinsing with ultra-pure water and drying in a clean environment will ensure optimal purity. Avoid abrasive materials that could scratch the surface.
While fused quartz has superior mechanical strength and thermal properties compared to borosilicate glass, it’s important to note that standard Erlenmeyer flasks are not typically designed for full vacuum applications, regardless of material. The conical shape, while robust for heating and mixing, is not optimal for sustained high vacuum without risk of implosion. For strong vacuum or pressure applications, we recommend specialized heavy-wall quartz vessels, which can be custom-fabricated to meet specific pressure ratings and safety standards.
