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.

Abstract: PURPOSE:To improve a washing effect and to make a quick and highly effective measurement of organic contamination turbidity possible, by carrying out automatic washing and manual washing by jetting air in a passing hole of a liquid to be inspected or inserting a freely detachable manual brush. CONSTITUTION:When an air pump 24 is started, air bubbles are jetted from an opening 27 of the lower part of a measurement cell 5 and a compensation cell 6 of a detection part for measurement 4 and contaminants stuck to the cells 5, 6 are washed automatically. Next, when the pump 4 is stopped and an air pump 25 is started, the bubbles are jetted from an opening 29 of the upper part of the cell 5, 6 and pressure difference is brought out between the upper and lower sides of the cells 5, 6. Then, circulation of a liquid to be inspected is accelerated and the degree of contamination turbidity of the liquid to be inspected is measured in accordance with the absorption rate of ultrviolet rays etc. On one hand, when manually operating brushes 31, 30 are inserted into each cell 5, 6 through a movable pipe, the cells 5, 6 are washed manually. The degree of organic contamination turbidity is measured quickly and highly effectively by impreving the washing effect by using jointly the automatic washing and manual washing.
