Custom 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.

高温耐性
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.
耐食性
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.
アプリケーション・シナリオ
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.
よくある質問
石英ガラスは硬くて脆い材料で、物理的、化学的性質が優れ、機械的硬度が非常に高く、電気絶縁性がよく、高温と耐食性に優れ、遅延性能が低く安定で、光透過性がよい。半導体、光学、電気、化学、航空宇宙、自動車などの分野で広く使用されている。硬くて脆い材料は加工が難しく、多くの分野で刃先の倒れが小さく、材料ロスが少なく、断面粗さが小さく、切断厚さ範囲が広い切断加工が急務となっている。石英ガラスの伝統的な切断方法は機械的切断、すなわち砥石切断である。非伝統的な切断方法には、ウォータージェット切断、電気化学放電ワイヤー切断、連続レーザー切断などがある。機械的切断はコストが低いが、ホイールと材料が接触するため工具の摩耗が大きく、材料が工具によって汚染されやすい。石英ガラスはエッジ崩壊、マイクロクラック、残留応力が発生しやすく、材料の強度や性能に影響する！曲線切断が難しく、研削や研磨などの後処理が必要。レーザー切断は材料に直接触れないため、接触応力がなく、複雑な曲線切断が可能です。ピコ秒レーザーは、スポット径が小さい、精度が高い、材料との作用時間が短い、作用面積が小さいなどの利点があり、硬くて脆い材料の加工に適しています。
