Aplicaciones químicas y de laboratorioCustom quartz petri dishes are laboratory glassware made to a customer’s specific needs and specifications. They are crafted from high-purity quartz glass (99.998% SiO2) and offer properties such as high-temperature resistance, corrosion resistance, good thermal stability, high light transmittance, and excellent electrical insulation. These dishes can be customized to various sizes, shapes, and specific application requirements, making them suitable for a wide range of laboratory uses, including cell and microbial culture. Suppliers offer customization services for sizes ranging from 10 mm to 300 mm, ensuring products maintain their shape with a smooth growth surface. Custom quartz petri dishes are also widely used in high-temperature and strong acid/base environments in areas such as epidemic prevention stations, hospitals, biological product facilities, and the food and pharmaceutical industries.

Resistencia a altas temperaturas
Quartz petri dishes can withstand extremely high temperatures, with long-term working temperatures ranging from 1100°C to 1250°C and short-term exposure to temperatures up to 1450°C.
Corrosion Resistance
Quartz glass is inert to almost all acids (except hydrofluoric acid), offering superior acid resistance that is 30 times greater than that of ceramics and 150 times greater than that of stainless steel.
High Light Transmittance
Quartz glass exhibits excellent light transmittance across the entire spectrum from ultraviolet to infrared. Its visible light transmittance is greater than 95%, and its maximum transmittance in the ultraviolet spectral range exceeds 85%.
Chemical Stability
Quartz glass has exceptional chemical stability and does not readily react with other chemical substances. This makes it a popular choice in laboratories, especially for experiments where maintaining the purity of the vessel is critical.

Cell Culture
In biomedical research, quartz petri dishes are used for cell culture and observation because they provide a sterile and chemically stable environment.
Microbiology Research
They are used for the isolation, cultivation, and identification of microorganisms such as bacteria and fungi. Quartz petri dishes are suitable for a variety of microbiological experiments due to their high-temperature and corrosion-resistant properties.
High-Temperature Experiments
In chemical experiments requiring high-temperature processing, such as ashing and melting, quartz petri dishes are widely used because of their ability to withstand high temperatures.
Optical and Ultraviolet Experiments
Because of their high light transmittance, quartz petri dishes are useful in optical and ultraviolet light experiments, particularly in ultraviolet spectroscopy analysis where high transmittance is essential.
Quartz petri dishes can withstand extremely high temperatures. Their long-term working temperatures range from 1100°C to 1250°C, and they can withstand temperatures up to 1450°C for short durations.
Quartz petri dishes are inert to almost all acids, except for hydrofluoric acid. Their acid resistance is 30 times greater than that of ceramics and 150 times greater than that of stainless steel.
Quartz petri dishes have excellent transmittance across the entire spectrum from ultraviolet to infrared. Their visible light transmittance is greater than 95%, and their maximum transmittance in the ultraviolet spectral range is over 85%, making them very suitable for experiments requiring high light transmittance.

Preguntas más frecuentes
El vidrio de cuarzo es un material duro y quebradizo con excelentes propiedades físicas y químicas, dureza mecánica extremadamente alta, buen aislamiento eléctrico, resistencia a altas temperaturas y a la corrosión, rendimiento de retardo bajo y estable, buena transmitancia luminosa, etc. Se utiliza ampliamente en semiconductores, óptica, electricidad, química, aeroespacial, automoción y otros campos. Los materiales duros y quebradizos son difíciles de procesar, y muchos campos necesitan urgentemente procesos de corte con un pequeño colapso del borde, menos pérdida de material, baja rugosidad de la sección transversal y un amplio rango de grosor de corte. El método de corte tradicional del vidrio de cuarzo es el corte mecánico, es decir, el corte por disco. Los métodos de corte no tradicionales incluyen el corte por chorro de agua, el corte por hilo de descarga electroquímica, el corte por láser continuo, etc. El corte mecánico tiene un bajo coste, pero el contacto entre la rueda y el material causa un gran desgaste de la herramienta, y el material es fácilmente contaminado por la herramienta. El vidrio de cuarzo es propenso al colapso de los bordes, las microfisuras y la tensión residual, lo que afecta a la resistencia y el rendimiento del material. Es difícil conseguir un corte curvo y requiere un tratamiento posterior, como esmerilado y pulido. El corte por láser no entra en contacto directo con el material, no tiene tensión de contacto y puede realizar cortes curvos complejos. El láser de picosegundos tiene las ventajas de un diámetro de punto pequeño, alta precisión, tiempo de acción corto con el material y área de acción pequeña, y es adecuado para el procesamiento de materiales duros y quebradizos.
