Abstract

A transfer jig has a main body capable of housing a tubular first cylinder for collecting a vaporized organic material, and the main body housing the first cylinder is housed inside a tubular second cylinder of a purification apparatus. A loading method has: a step of housing, in the main body of the transfer jig, the tubular first cylinder for collecting a vaporized organic material; and a step of inserting and removing the transfer jig housing the first cylinder into and from the tubular second cylinder of the purification apparatus.

Description

technical field [0001] The invention relates to a handling tool, a filling method, and a purification method. Background technique [0002] If impurities are mixed in materials (hereinafter, sometimes simply referred to as organic EL element materials) used in organic electroluminescent elements (hereinafter, sometimes simply referred to as organic EL elements.), the impurities become carriers (electrons, holes) or become a cause of extinction, leading to a decrease in the luminous intensity, luminous efficiency, and durability of the organic EL element. Therefore, in order to reduce impurities, it is necessary to refine the material for organic EL elements to high purity. [0003] As a purifying apparatus for purifying organic materials such as materials for organic EL elements, it is described in Patent Document 1, for example. [0004] In addition, as another purification device, there is, for example, a device that accommodates an inner cylinder in an outer cylinder, s...
