Advantages of Quartz Test Tube

Durable
Borosilicate glass is known for its durability, making it resistant to breakage and thermal shock.

Chemical resistance
Borosilicate glass is highly resistant to chemicals, making it ideal for labs that work with corrosive substances.

Cost
While borosilicate glass test tubes are typically more expensive than plastic test tubes, they are still more affordable than Pyrex.
Applications of Quartz Tubes
High-Temperature Furnaces: They are used as reaction vessels or protective enclosures in high-temperature furnaces due to their ability to withstand extreme heat and thermal cycling.
Chemical Reactions: Their chemical inertness makes them ideal for conducting reactions involving aggressive chemicals or for processes requiring a contaminant-free environment.
Spectroscopy and Optical Instruments: The optical clarity and UV transparency of quartz tubes are essential in spectroscopy, where they are used as sample containers or light guides.
Diffusion and Oxidation Processes: They are widely used in semiconductor manufacturing, particularly in diffusion and oxidation furnaces, where their high purity and thermal stability are critical.
Wafer Processing: The tubes serve as enclosures for semiconductor wafers during various high-temperature processes, ensuring minimal contamination and consistent thermal distribution.
Germicidal Lamps: Quartz tubes are used in UV germicidal lamps, where their high UV transmission allows for effective disinfection of air, water, and surfaces in medical, industrial, and residential settings.
Water Purification Systems: They are used in UV water purification systems, where they protect the UV lamps and ensure efficient UV light transmission.
Heating Elements: They are used as protective sheaths for heating elements in industrial furnaces and heaters, particularly in processes that require uniform and controlled heating.
Glass Manufacturing: In glass production, quartz tubes can be used to house high-intensity lamps or as part of the equipment used in glass processing.
Optical Fibers: They are used in the production of optical fibers, where their transparency and purity ensure efficient light transmission with minimal loss.
Laser Systems: They are also used in laser systems as beam guides or enclosures, benefiting from quartz's high optical clarity and resistance to heat.
Gas Analyzers: They are employed in environmental monitoring equipment, such as gas analyzers, where their chemical resistance and transparency are crucial for accurate readings.
Aerosol Research: In aerosol research, quartz tubes are used to collect and analyze particulate samples, leveraging their inertness and thermal stability.

Advantages of Quartz Beaker
High working temperature
Softening point is about 1730 degrees Celsius, long time using at 1100 degrees Celsius, short-term maximum working temperature is up to 1450 degrees Celsius.
Anti-corrosion
In addition to hydrofluoric acid, quartz is chemically nonreactive to any other acids, quartz's performance in high temperature far exceeds other common materials.
Thermal stability
The thermal expansion coefficient of quartz is very small, thus quartz beaker is able to withsand drastic temperature changes.
Photopermeability
In the ultraviolet to infrared spectral bands quartz is with high light transmission rate, transmittance of visible light is over 93%, and 80% of the ultraviolet.
Insulativity
Quartz's specific resistance is far lower than glass, it's considerd to be a good insulator, even in high temperature, quartz can still keep its electric insulativity.
