Pretreatment kit, pretreatment apparatus for pretreatment of sample using the pretreatment kit, and analysis system including the pretreatment apparatus

摘要

A preprocessing kit includes a separation device, a collecting container, and a skirt part. The separation device is a cylindrical container which has an upwardly-open internal space, and includes a separation layer which allows a sample to penetrate and separates a specific component in the sample from the sample, in the internal space, and an extraction outlet for extracting the sample penetrating the separation layer, in a lower end. The collecting container is attachable to and detachable from the separation device, has an internal space in which an extracted sample provided from the extraction outlet of the separation device is collected, and is fitted into a recess part forming a filtration port for performing filtration processing on a sample with a lower end of the separation device of the separation device being contained in the internal space. The skirt part is integrated with the separation device, and is provided to surround an outer circumferential surface of the separation device with a clearance being left from the outer circumferential surface so that a space having a closed upper side and an open lower side is formed between the outer circumferential surface of the separation device and the skirt part. The skirt part is provided in such a way that a lower end of the skirt part comes into intimate contact with a peripheral surface of an opening of the recess part when the collecting container containing the lower end of the separation device is fitted into the recess part.
