PURPOSE:To handle a liquid container in safety by boring at least two holes which have cylindrical internal surfaces in a top surface, making the bottoms of the holes into planes perpendicular to the axes of the cylinders, and further boring a hole which has a cylindrical internal surface and does not penetrate the bottom in one of the two holes. CONSTITUTION:The 1st cylindrical hole 4 and the 2nd cylindrical hole 5 are provided in a main holder 1, and the 2nd hole 5 is a little bit shallower than the 1st hole 4. Further, the 3rd hole 6 which has the cylindrical internal surface is formed in the bottom surface of the 2nd hole 5 and does not penetrates the holder 1 to its bottom surface 2. The depths of the holes 4, 5, and 6 are selected properly according to the lengths of containers to be stored. When >=2 kinds of valuable liquid such as sample liquid and standard liquid are handles, their liquid containers are held stably in a hard-to-fall state and in an easy-to-take-out state.
