FAQ
Q: What is the maximum temperature for these graphite crucibles?
A: These high-purity graphite crucibles can be used up to 3000°C in vacuum or inert atmosphere (argon, nitrogen). In air, graphite oxidizes rapidly above 500°C, so use must be in controlled atmosphere.
Q: Can you produce custom-sized crucibles for specific furnace models?
A: Yes, we manufacture custom graphite crucibles based on your drawings or furnace dimensions. Please provide your required dimensions or send us your old crucible for reference.
Q: Do you offer small quantity orders for university labs?
A: Yes, we welcome small orders for university and research laboratories. Standard sizes are available in small quantities with fast shipping. Please contact us for pricing and availability.
