PURPOSE:To achieve an accurate and stable quantitative sampling by mounting a sample liquid sampling container detachably on a needle sampling pot together with a support to inject a sample liquid stored in the sampling pot thereinto. CONSTITUTION:A ceiling wall section 1b exists above a storage section 1a and a hole 7 for mounting a support 2 of a needle 4 at the center thereof. The top of the support 2 is so formed to fit the mouting hole 7 that the support 2 is detachable from the mounting hole 7. The storage section 1a is always filled with a sample liquid and a water separation is performed at the top of the storage section 1a while the lower end of the needle 4 is opened near the bottom of the storage section. This eliminates the mixing of air into a sample liquid sampling container thereby accomplishing an accurate and stable quantitative sampling. |
