Extreme High-Temperature Resistance
Engineered from pure quartz, these flasks can stably withstand temperatures up to 1200°C, with flash heating capability up to 1450°C. This makes them ideal for reactions, distillations, and heating processes far beyond the limits of conventional borosilicate glass.
Superior Chemical Inertness
Highly resistant to nearly all acids (with exceptions for HF and hot phosphoric acid) and alkalis, these flasks ensure minimal interaction with reactants. This prevents contamination and degradation of the flask, crucial for sensitive chemical synthesis and analysis.
High Purity & Optical Clarity
Crafted from high-purity quartz, the flasks themselves do not introduce impurities, making them perfect for high-purity chemical reactions and trace analysis. Their excellent optical transparency allows for clear visual monitoring of reaction progress without obstruction.
Robust Construction & Customization Options
Featuring a sturdy, rounded bottom and a precision frosted ground joint, these flasks are built for durability and provide a secure, leak-proof connection to other lab apparatus. Furthermore, they support customization in terms of capacity, joint sizes, and specific design modifications to meet unique experimental requirements.
Application Scenario
High-Temperature Chemical Synthesis & Reaction
Ideal for conducting chemical reactions, reflux, or heating processes that require temperatures far exceeding what borosilicate glass can handle (up to 1100°C stable, 1450°C flash). This is common in inorganic chemistry, materials science, and catalytic research.
Acid Digestion and Strong Corrosive Reactions
Used extensively for sample digestion with strong acids (excluding hydrofluoric acid and hot phosphoric acid) or for reactions involving highly corrosive chemicals, where the superior chemical inertness of quartz prevents flask degradation and sample contamination.
High-Purity Distillation & Reflux
Perfect for the distillation of high-purity solvents or refluxing sensitive reaction mixtures where metal ion leaching or contamination from standard glassware is unacceptable, leveraging quartz’s exceptional purity.
Vacuum Evaporation & Drying
Due to their robust construction and ability to withstand thermal stress, these flasks are suitable for vacuum evaporation processes, solvent removal, or drying of compounds at elevated temperatures, often connected to rotary evaporators or vacuum lines.
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 single-necked flasks offer significantly superior thermal shock resistance compared to borosilicate glass. This is due to quartz’s extremely low coefficient of thermal expansion, allowing it to withstand rapid temperature changes without cracking or breaking, even from ambient to very high temperatures, which is a major advantage in demanding lab operations.
Yes, absolutely. Quartz single-necked flasks with their precision ground joints are highly suitable for vacuum applications, including rotary evaporation, vacuum distillation, and other processes requiring a robust, leak-tight seal. Their thick walls and inherent strength make them resistant to implosion under typical laboratory vacuum conditions.
These quartz single-necked flasks are commonly available with standard taper ground joint sizes (e.g., 14/20, 19/22, 24/40, 29/32, etc.) to ensure compatibility with a wide range of laboratory apparatus. While the flask itself is typically sold separately, matching quartz glass stoppers or other joint accessories are available for purchase to complete your setup.
