PURPOSE:To reduce an measurement error caused by evaporation of a sample without impairing operability of sampling, by forming a small hole for inserting a sampling nozzle through the cap. CONSTITUTION:A small hole 4a is formed through the center of the cap 4 used for the sampling cup to enable insertion of the sapling nozzle. Such a constitution suppresses evaporation of the sample contained in the sampling cup without impairing operation of sampling, and reduces a measurement error due to its evaporation. |
