Vertical Tube Furnace

A vertical tube/split tube furnace is a type of high-temperature heating apparatus used to process samples vertically in a cylindrical tube. It is perfect for uses that need for regulated atmospheres, homogenous heating, gravity-assisted reactions like quenching and processes involving gas solid interactions like the ones in catalysis and fluidized bed reactions.

For procedures like crystal formation, vapor phase reactions, and thermal decomposition, the vertical arrangement makes it simple to load crucibles, boats, or sample holders from the top. The furnace is designed to be precise and dependable, with high thermal uniformity, sophisticated temperature control, and adaptable tube designs to suit a range of commercial and research requirements.
