High temp. Sliding tube furnace

High Temperature Sliding Tube Furnace, BTF-1700C-S-SL

Can slide out the sample through the rail,convenient and reliable to take and put the sample.

With double air cooling structure, the temp. of shell is lower than 60℃ when heat to highest temp.

Furnace chamber adopt inorganic materials of alumina fiber by vacuum adsorption,clean and beautiful

Equipped with support frame for flange, reduce the load of tube body

With mature technology, high quality, uniform thermal field, rational construction
