Extreme High-Temperature & Chemical Resistance
Crafted from high-purity quartz, these threaded bottles can withstand very high temperatures and exhibit superior inertness to a wide range of corrosive acids, alkalis, and organic solvents, ensuring sample stability and bottle integrity in harsh environments.
Exceptional Purity & Non-Contaminating
Made with SiO2 purity of ≥99.99%, these bottles are free from bubbles and color lines, significantly reducing the risk of leaching and cross-contamination. This makes them ideal for storing and handling high-purity reagents and sensitive analytical samples.
High Optical Transmittance (UV & Visible)
The clear, high-transmittance quartz material allows for excellent light penetration across a broad spectrum, including UV, visible, and near-IR regions. This is particularly beneficial for applications requiring spectroscopic analysis or photochemical reactions.
Secure Screw Top & Versatile Specifications
The precision-threaded neck ensures a tight, reliable seal when paired with an appropriate cap, preventing leakage and evaporation. Furthermore, their availability in complete specifications offers versatility, allowing for various sample volumes and compatibility with diverse laboratory setups.
Application Scenario
High-Temperature Sample Storage & Reactions
Ideal for storing and reacting samples at elevated temperatures where a secure, threaded closure is required. This includes thermal stability studies, aging tests, or short-term high-temperature chemical reactions in a sealed environment.
Storage of Corrosive Chemicals & Reagents
Used for the safe and long-term storage of aggressive acids, strong alkalis, and various organic solvents. The superior chemical inertness of quartz ensures that the bottle does not degrade or leach impurities into the corrosive contents.
High-Purity Sample Collection & Transport
Essential in fields requiring ultra-low contamination, such as environmental analysis, semiconductor manufacturing, and pharmaceutical quality control. These bottles provide a non-contaminating, high-purity container for sensitive samples during collection, transport, and storage.
UV-Sensitive Reactions & Spectroscopic Sample Prep
Due to quartz’s excellent transparency in the ultraviolet (UV) range, these threaded bottles are suitable for conducting small-scale UV-induced photochemical reactions or for preparing and holding samples for UV-Vis spectroscopy, where light transmission is critical.
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 threaded bottles are designed for use with standard screw caps, often made from polypropylene or other chemically resistant plastics, usually with a septum liner (e.g., PTFE/silicone). While the bottles themselves are typically sold, matching caps and septa are usually available separately to ensure you can achieve a proper, leak-tight seal based on your specific application needs.
Quartz threaded bottles offer significantly superior chemical resistance compared to both borosilicate glass and most plastics. They are highly inert to nearly all acids (with exceptions for hydrofluoric acid and hot phosphoric acid) and strong bases, as well as many organic solvents, at temperatures where other materials would degrade or leach contaminants. This makes them ideal for the most aggressive and sensitive chemical applications.
Yes, quartz threaded bottles can be sterilized using various methods due to their high thermal stability and chemical resistance. Autoclaving (steam sterilization) is a common and effective method. They can also be sterilized by dry heat (up to their maximum temperature limit), chemical sterilization using strong acids or bases, or UV irradiation due to their transparency. Always ensure thorough rinsing after chemical sterilization.
