Document Type and Number:
WIPO Patent Application WO/2014/129809
Kind Code:
A1
Abstract:
The invention is related to an inner tube, especially an inner tube for collecting a purified material, used in an apparatus for sublimation-purification of OLED materials. The surface area or size of the conventional inner tube used for a sublimation-purification apparatus is limited to the surface area or size of an outer tube, and thus the amount of material obtained in one process is restrictive thereby. The present invention provides an inner tube for improving productivity of the purified material compared to the conventional inner tube.
