Frequently Asked Questions
1. What is the difference between Haldenwanger porcelain and Alsint 99.7?
Standard laboratory porcelain is suitable for temperatures up to 1000°C. Alsint 99.7 is a high-purity alumina ceramic that can handle significantly higher temperatures (up to 1700°C) and offers better chemical resistance.
2. Can Haldenwanger crucibles be used in a muffle furnace?
Yes, Haldenwanger crucibles are specifically designed for use in muffle furnaces for applications such as ashing, tempering, and melting of samples.
3. Are the Buchner funnels resistant to strong acids?
Haldenwanger porcelain funnels offer excellent resistance to most acids and alkalis, except for hydrofluoric acid, which will attack the ceramic structure.
4. Should I heat Haldenwanger ceramics gradually?
While materials like Pythagoras offer good thermal shock resistance, it is always best practice to avoid rapid temperature changes to maximize the lifespan of any technical ceramic component.
