ANALYSIS PREPTREATMENT APPARATUS

PROBLEM TO BE SOLVED: To provide an analysis pretreatment apparatus in which an analysis pretreatment can be executed stably while the activity of a sample liquid injected into a test tube with a ground stopper is being maintained. SOLUTION: A cooling device which blows a cool wind, from opened side faces of stands S, to circumferential faces of test tubes T, with ground stoppers, which are supported by the stands S is provided. A wind tunnel 12 into which a cool wind is introduced from the outside is installed in the lower part of a table 11 in a stand housing part 1 in which especially a plurality of stands are housed side by side. In addition, a plurality of cool-wind blowoff ports 14 which communicate with the wind tunnel and which blow off cool winds are installed so as to be along the side faces of the stands. In addition wind deflecting plates 15 which deflect the cool winds to be blown off from the cool-wind blowoff ports toward the side faces of the stands are erected and installed respectively on the table along the opened side faces of the respective stands.
