<p>PROBLEM TO BE SOLVED: To maintain the interior state of a container by forming the all surface parts of a container interior part with any one of metal, glass, ceramic, and quartz or a combination of these substances except an organic material absorbing material part, and defining an air permeable penetration part via an organic matter absorption material. SOLUTION: A container main body 1 and an open and close part door 2 for taking in and out a sample is made of aluminum. A metal holding member 4 of a wafer 3 is manufactured of stainless steel. Between the open and close door 2 and the main body 1, a high purity aluminum gasket is used as a packing 5. In addition, a penetration part 8 for the inside and outside parts of the case is provided; then, powder activated charcoal is charged in this penetration part 8 as an organic material absorption material 10. By this construction, all surface parts being exposed to air are metal except the organic matter absorbing material 10, and also, it includes the penetration part 8 via the organic matter absorbing material 10, an organic matter pollution caused by the container per se can be prevented during storage or transportation of an sample.</p> |
