Laboratory round quartz glass window
In the field of scientific research and industrial experiments, it is essential to observe and monitor the experimental process. As a key component, the laboratory round quartz glass window provides a clear and stable observation window for experiments under various harsh conditions with its excellent physical and chemical properties. It not only ensures the visibility of the experiment, but also greatly affects the success or failure and safety of the experiment.
The round quartz glass window in the laboratory, as the name suggests, is a transparent observation window with a circular profile processed from high-purity quartz glass (mainly composed of silicon dioxide, SiO _ 2). It is usually inlaid or sealed on the shell of the experimental equipment (such as reaction kettle, autoclave, oven, vacuum chamber, melting furnace, etc.), allowing researchers to directly observe the physical state changes, reaction process, color changes, bubble formation and other key phenomena of the experimental substance without disturbing the internal environment of the experiment.
Core advantages:
Extremely high temperature resistance: quartz glass has a softening point of up to about 1730 ° C and can be used for a long time at 1100 ° C, far exceeding ordinary glass and able to withstand most high temperature experimental environments.
Exceptional optical properties: It has excellent transmittance in the entire spectral range of ultraviolet to infrared (UV-VIS-IR), especially the transmittance of ultraviolet light is much higher than that of ordinary glass, making it suitable for experiments requiring ultraviolet observation or UV light source penetration.
Excellent chemical stability: It can resist the corrosion of most acids (except hydrofluoric acid and hot phosphoric acid), salts, and solvents, and its alkali resistance is also better than that of ordinary glass, ensuring stability in a chemically corrosive environment without introducing impurities.
Low thermal expansion coefficient: very small thermal expansion coefficient (about 0.54 x 10 /K), good thermal shock resistance, can maintain dimensional stability under severe temperature changes, not easy to break.
High mechanical strength: Although brittle, it has sufficient compressive strength to withstand certain internal pressures or external shocks.
High purity: The raw materials are of high purity, do not contain harmful impurities, and do not contaminate the experimental samples.
Application
The application of round quartz glass windows in laboratories is extremely extensive, covering almost all experimental scenarios that require visual monitoring of internal processes.
High-temperature chemical reaction: In a high-temperature and high-pressure reactor, observe the melting, vaporization, and color change of the reactants. For example, organic synthesis, inorganic material synthesis, polymerization, etc.
Materials science: observe the phase transformation, melting behavior and grain growth process of materials at high temperature. Such as metal smelting, ceramic sintering, glass melting, etc.
Semiconductor and Optical Manufacturing: Monitor temperature distribution, gas flow, deposition uniformity, etc. in quartz tube furnaces or reaction chambers for semiconductor wafer processing, thin film deposition (e.g. PECVD), annealing, and other processes.
Vacuum technology: In vacuum coating equipment, vacuum drying oven, and vacuum reactor, observe the internal sample status or internal conditions of the equipment.
Food and pharmaceutical industry experiments: In experimental-scale sterilization, drying, crystallization, and other equipment, monitor the condition of materials to ensure that the process meets requirements.
Environmental and energy research: observation of reaction phenomena in experimental devices such as simulated high-temperature combustion, catalytic reaction, and photocatalytic degradation.
Physics and Chemistry Teaching Demonstration: In university laboratories, it is used to demonstrate high temperature, high pressure or corrosive experiments to enhance teaching intuitiveness.
Ultraviolet/visible/infrared optical experiments: as a light source or detector window, leveraging its broad spectral transmission characteristics.
Custom description
Due to the diversity of experimental equipment and experimental conditions, laboratory round quartz glass windows usually need to be customized according to specific needs. Customization content mainly includes the following aspects:
Dimensions:
Outer Diameter (OD): Determines the installation size of the window on the device housing.
Inner diameter (ID): If the window has a flange or other structure, the inner diameter is the key dimension.
Thickness: Determined according to the pressure, temperature range and mechanical strength requirements required. Usually the higher the pressure and temperature, the greater the required thickness. Common thicknesses range from a few millimeters to twenty or thirty millimeters.
Roundness and parallelism: High-precision roundness and parallelism are essential to ensure sealing and installation accuracy.
Edge processing:
Chamfer/deburring: Prevent sharp edges from causing damage or scratching the seal during installation or use.
Scrub/Polish: Depending on the optical requirements, the surface may require high-precision polishing for optimum transmittance, or a light matte treatment for added safety (anti-glare).
Installation structure:
Structural/planar: The simplest form of a direct compression seal.
With flange: The window edge has a raised flange edge for stronger bolting and sealing to the equipment housing.
Threaded: The edge of the window is machined into internal or external threads for screwing into specific joints.
Special sealing groove: Sealing groove is designed according to a specific sealing method (e.g. O-ring seal).
Optical performance requirements:
Spectral range: Identify the transmission spectral range that needs to be optimized (e.g. UV enhancement, visible high transmittance, infrared transmittance, etc.).
Transmittance: Specific requirements for optical transmittance at specific wavelengths or across entire bands.
Surface quality: the level of surface defects (such as bubbles, impurities, scratches, pitting, etc.) is specified.
Special treatment:
Coating: According to requirements, anti-reflection film, reflective film, thermal insulation film, anti-reflection film, etc. can be plated on the surface.
Marking: Marking the number, model, or scale on the edge of the window or at a specific location.
Strengthening treatment: Tempered or heat-treated windows to improve their mechanical strength and thermal shock resistance (but may sacrifice some optical properties).
Material grade:
According to the purity requirements of the experiment, different grades of quartz glass can be selected, such as electronic grade, optical grade, chemical grade, etc.
Laboratory round quartz glass windows are an indispensable component in modern experimental research, and their excellent performance and flexible customization capabilities enable them to meet a variety of complex and demanding experimental observation requirements.
