Shemle Tube ((better)) 〈ULTIMATE〉

A Shemle tube (often misspelled as "Shemle tube" or confused with similar apparatus) is a type of ceramic or refractory tube used in high-temperature furnaces, material testing, and thermal analysis. It is most commonly associated with thermogravimetric analysis (TGA) and differential thermal analysis (DTA) equipment, where it serves as a protective and sample-holding chamber.
