High purity alumina ceramic process tube for metal casting or ceramic sample preparation, designed to fit our TF furnaces.
Note: Not compatible with our STF1200, TFM2.1200 and TFM3.1200 series furnaces.
The process tube is the working chamber of a tube furnace: samples sit inside it while the heating elements surround it, and with sealing flanges fitted it can hold a vacuum or a controlled gas atmosphere.
With over 99.5% alumina and less than 0.01% iron oxide, the tube stays clean and stable at working temperatures up to 1750°C. Its impervious body is rated to hold vacuum down to 0.001 Pa, but positive pressure is limited to 3 psi, so gas flow should vent freely rather than build up in the tube.
Pair the tube with alumina thermal blocks placed in front of the sealing flanges to keep heat away from the flange gaskets.

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
