Will the pan keep its integrity in a muffle furnace at 550C?

These weigh pans are made of Aluminum and have a maximum operating temperature of 677°C. Our aluminum weigh pans handle the muffle furnace temperature of 550°C very well. However, the pan labels with the lot numbers and tare weights will burn off in the muffle furnace. I always recommend “writing” either the pre-weight or ID or both on the bottom of the pan with a pencil – you are actually making an indentation on the pan at that point. If you write with a Sharpie it also burns off but the indentation holds up well.

Do you have a question?
