The plurality of rings stacked at regular intervals from each other are connected and coupled to each other by using a sealing material S on the inner surface thereof, thereby maintaining the outer shape of the case 32 and the sample container 34. The reason for forming the gap is to allow the pure water to flow out of the sample container 34 and the case 32 during sampling, and to collect only the resin.

In addition, the lower end of the case 32 and the sample container 34 should be sealed so that the collected resin can be contained.

Therefore, when the sample container 34 enters the pure water tank T while being embedded in the case 32, the sample container 34 is filled with pure water and resin, and the sampling operation proceeds sufficiently so that the sampler is filled. In the process of drawing 30 from the pure water tank T, the pure water exits at intervals formed between the plurality of rings forming the sample container 34 and the case 32, and is again contained in the pure water tank T. Only the resin in the solid state can be taken out while contained in the sample container 34.
