SPECIFICATION - Quantity: 20pcs, size: diameter * height, capacity: 25-85ul, alumin≥ 99%, type: with lid/without lid, high temperature resistance: 1600-1750℃.THERMAL ANALYSIS CRUCIBLE - High thermal conductivity, fast heat transfer between sample and crucible, uniform temperature distribution, stable structural performance, not easy to have physical and chemical reaction with analyzed sample.CONTROL HEATING/COOLING RATES - Excessive temperature change rates cause cracking! below 1200℃: 4℃/min, above 1200℃: 3℃/min, use power-controlled cooling, avoid rapid cooling by turning off power while hot, as initial furnace cooling is often too fast. (For larger products, use slower rates ≤2℃/min)AVOID DIRECT FLAME / LOCALIZED HEATING - Do not heat directly with gasoline torches, acetylene guns, alcohol lamps, or by with hot objects, uneven heating causes cracking.FIRST USE - Place in a ~105℃ oven for 120 minutes, or follow the process recipe for an initial empty firing to remove moisture/impurities.SPECIFICATION - Quantity: 20pcs, size: diameter * height, capacity: 25-85ul, alumina≥ 99%, type: with lid/without lid, high temperature resistance: 1600-1750℃.
- High thermal conductivity ensures rapid heat transfer between samples and crucibles, providing uniform temperature distribution for accurate analysis.
- Includes 20 pieces with a capacity range of 25-85µL, available in both with lid and without lid options to suit various experimental needs.
- devised for high-temperature resistance, these crucibles can withstand temperatures from 1600℃ to 1750℃, making them ideal for demanding thermal analysis applications.
- Carefully control heating and cooling rates to prevent cracking; recommended rates are 4℃/min below 1200℃ and 3℃/min above 1200℃.
- Initial use requires preheating in a 105℃ oven for 120 minutes to eliminate moisture and impurities, ensuring optimal performance during experiments.
