Abstract: PURPOSE:To efficiently and completely filtrate and eliminate impurities such as an unnecessary suspension, etc., and to discharge them to the outside of a system by connecting a network tube having a mesh diameter which can filtrate and separate the suspension, etc., contained in a liquid, into a feed liquid pipe-line for feeding by pressure a sample liquid to an analyzing device, etc. CONSTITUTION:A network tube 4 is a flexible and elastic tube made of a fibrous matter or a sponge, etc., having fine holes of a mesh diameter which cannot allow a suspension contained in the sample liquid, or a minute solid mater to transmit through, and provides so as to be pressed in a U-shape against the plural pieces of press rollers 7 provided between two pieces of disks 5 attached to a shaft 6. In such a way, when the disks are rotated in a direction as indicated with an arrow, the tube 4 is pressed by the rollers 7, and the sample liquid transmitted through its thin hole part oozes out of the surface of the roller 7 and drops down, collected to a sample liquid container 12 by a receiver 11, and fed to an analyzing device, etc., from a tube pipe-line 13 connected to said container. On the other hand, an unnecessary suspension, etc., left in the tube 4 are fed by pressure to an outlet tube 9 together with the remaining liquid,, and discharged to the outside of a system therefrom.
