Quartz Glass Petri Dishes with Lid - Flat-Bottom, High-Temperature Resistant, Ideal for Lab Use (Φ30/40/50/60mm)(OD50x2x15mm)

This series of glassware is made of quartz glass, with a SiO2 content greater than 99.5%, a low coefficient of thermal expansion, high temperature resistance, and good chemical stabilityThe welding process is adopted, making the surface neater, the dimensions more precise, and the tolerance ± 0.1mmQuartz glass material has extremely high thermal stability and can withstand drastic temperature changesQuartz glass is an acidic material. When used at high temperatures, it is strictly forbidden to come into with alkaline substances; otherwise, its anti-crystallization performance will be greatly reducedDetailed parameters are provided in the options. The diameter is the external diameter. Each set comes with a lid. Please carefully confirm and select the appropriate size when purchasing
