Claims

[Scope of Claim for Utility Model Registration] A hollow cylindrical reservoir body with one end closed and the other end open to serve as a sample injection port, and a depression extending from the middle part to one end on the side of the reservoir body. a reservoir body side filtration material holding surface formed in the longitudinal direction of the reservoir body on the surface of the depression, and a reservoir body side window hole that is transparently provided in the reservoir body side filtration material holding surface and communicates with the internal hollow. and a hollow reservoir that is fitted into the recessed portion of the reservoir body without a gap and has an extraction hole that is formed at the end of the reservoir body on the side corresponding to the one end of the reservoir body and communicates with the internal hollow. a guide section; a reservoir guide section-side filtration material holding surface formed on a fitting side surface of the reservoir guide section and connected to the reservoir main body side filtration material holding surface via a joining means or engagement means; A reservoir guide side window hole is transparently provided in the filter material holding surface on the reservoir guide side, and is aligned with the reservoir body side window hole so as to communicate with the inner hollow of the reservoir body and the inner hollow of the reservoir guide. , an ultrafiltration material that is sandwiched between the reservoir main body side filter material holding surface and the reservoir guide section side filter material holding surface and filters the sample through the reservoir main body window hole and the reservoir guide section side window hole; A liquid filtration device comprising: a cap that freely opens and closes a sample injection port; and a filtration cup attached to the extraction hole of the reservoir guide.
