FAQ
Q: What sizes of lab crucibles do you stock?
A: We offer a range of standard sizes from 10ml to 500ml capacity. Common sizes include 30ml, 50ml, 100ml, 200ml, and 300ml. For custom sizes or special geometries, please provide your specifications and we will manufacture to order.
Q: Can these crucibles be used in a muffle furnace in air?
A: Graphite crucibles can be used in air up to approximately 450°C before significant oxidation occurs. For higher temperature operation in air, we recommend using a ceramic crucible or placing the graphite crucible inside a protective outer crucible. For temperatures above 450°C, use in vacuum or inert atmosphere.
Q: Do you offer discounts for bulk orders or educational institutions?
A: Yes, we offer volume discounts for bulk orders and special pricing for universities and research institutions. Please contact us with your quantity requirements and we will provide a competitive quotation. Shipping worldwide to research facilities is available.
