As transparent glass tubes made of quartz crystal, quartz tubes are widely used in the field of physical experiments because of its high temperature resistance, corrosion resistance and excellent optical properties.

1. Measurement of silica content by ultraviolet-visible absorption spectroscopy (UV-Vis)

Quartz tubes play a key role in UV-Vis absorption spectroscopy, especially when measuring silica (SiO 2) content. UV-Vis spectroscopy exploits the unique absorption characteristics of substances at different wavelengths. By comparing the sample spectrum with the standard spectrum, the wavelength affected by the sample can be accurately determined, and thus the silica content can be determined. Quartz tubes act as sample containers in this process, capable of withstanding ultraviolet light and maintaining optical transparency to ensure the accuracy of measurement.

2. Heating components for laboratory tube furnaces

Quartz tubes are widely used as heating components in laboratory tube furnaces due to their excellent thermal stability and high temperature resistance. At furnace temperatures up to 1200 ° C, quartz tubes remain stable and will not burst due to high temperatures. At the same time, quartz tubes have a very small coefficient of thermal expansion and can withstand severe temperature changes, making them ideal for high temperature experiments. In higher temperature furnaces, corundum tubes are usually selected as heating carriers.

3. Liquid level measurement

Quartz tubes also have important applications in liquid level measurement. It uses the principle of refraction and reflection of natural light in liquids to make the liquid phase appear green and the gas phase appear red through red and green sheets, so as to realize long-distance operation and night patrol. This liquid-gas phase display has the characteristics of large contrast and clear indication, which makes quartz tubes widely used in liquid level measurement of transparent liquid containers and boilers in petroleum, chemical, electric power, metallurgy and other industries.

4. Preparation of crystals by physical vapor transport

The quartz tubes are also used as a reaction vessel for the preparation of crystals by the physical vapor transport method. The physical vapor transport method uses the saturated vapor pressure characteristics of substances to produce gases at lower temperatures, and then condenses into solids at lower temperatures, thus realizing the growth of crystals. The quartz tubes have high degree of vacuum, which can avoid the influence of impurities and moisture and ensure the accuracy of the experiment. At the same time, the transparency of the quartz tube allows the experimenter to observe the growth process of the crystal and make real-time adjustments to the experiment.

5. Other physical experimental applications

In addition to the above applications, quartz tubes can also be used in a variety of physical experiments such as atomic absorption spectrometry and fluorescence spectroscopy. Its high temperature resistance, corrosion resistance and excellent optical properties make quartz tubes ideal for a variety of precision experiments.

Quartz tubes have a wide range of applications in the field of physical experiments, and their excellent physical and chemical properties make them the preferred material for various high temperature, high pressure, and high vacuum experiments. Quartz tubes demonstrate their irreplaceable importance by measuring silica content by ultraviolet-visible absorption spectroscopy, as heating components in laboratory tubular furnaces, for liquid level measurement, and for crystal preparation by physical vapor phase transport.
