What is the main advantage of quartz glass over borosilicate glass?\u003C/strong\u003E\u003Cbr /\u003EWhile borosilicate glass is excellent for general use, quartz glass offers much higher thermal resistance (up to 1100 \u0026deg;C) and superior UV transparency, as well as significantly higher purity for trace analysis.\u003C/p\u003E\u003Cp\u003E\u0026nbsp;\u003C/p\u003E\u003Cp\u003E\u003Cstrong\u003E2. Can proQuarz crucibles be used in muffle furnaces?\u003C/strong\u003E\u003Cbr /\u003EYes, proQuarz crucibles are specifically designed for high-temperature applications in muffle furnaces, providing excellent resistance to thermal shock and chemical attack during ashing processes.\u003C/p\u003E\u003Cp\u003E\u0026nbsp;\u003C/p\u003E\u003Cp\u003E\u003Cstrong\u003E3. Is quartz glass resistant to hydrofluoric acid?\u003C/strong\u003E\u003Cbr /\u003ENo. Like almost all glass types, quartz glass is susceptible to hydrofluoric acid and phosphoric acid at high temperatures. It should not be used with these specific chemicals if the integrity of the vessel is critical.\u003C/p\u003E\u003Cp\u003E\u0026nbsp;\u003C/p\u003E\u003Cp\u003E\u003Cstrong\u003E4. How should I clean my proQuarz glassware to maintain its purity?\u003C/strong\u003E\u003Cbr /\u003EFor general cleaning, standard laboratory detergents are fine. For high-purity applications, quartz glass can be cleaned with high-purity acids (except HF) to remove trace contaminants before rinsing with deionized water.\u003C/p\u003E","metaKeywords":"proQuarz, quartz glass, fused silica, laboratory glassware, technical glass, quartz beakers, quartz crucibles, semiconductor glass","metaDescription":"Experience extreme thermal resistance with proQuarz.
