    摘要: The blood filter unit of the invention is composed of a blood filtering material made of glass fiber filter and microporous membrane and a holder having a blood inlet and a filtrate outlet. The holder accommodates the blood filtering material so that the microporous membrane is located on the filtrate outlet side, provides a space between the blood filtering material and the filtrate outlet, and provides a means for preventing adhesion of the blood filtering material on the filtrate outlet side. By using the blood filter unit, a necessary volume of plasma or serum for analysis can be separated surely, irrespective of hematocrit value of the blood.

    摘要: The invention provides a blood filter cartridge which is made so that the filtrate discharged from the filtrate outlet is not drawn back to the inside of the filtering chamber. The blood filter cartridge includes a blood filtering material, a holder containing the blood filtering material and having a blood inlet and a filtrate outlet, and a filtrate receiver which receives the filtrate discharged from the filtrate outlet. The blood filter catridge is provided with a means for preventing the filtrate in the filtrate receiver from returning to inside of the holder upon finishing filtration. Such means include the following: removing opposite faces around the filtrate outlet, making length of lower end of the filtrate outlet 0.8 mm or more, smoothing surface around the filtrate outlet, and forming surface around the filtrate outlet by a material having a small surface energy.

    摘要: A device for determining ionic activity composed of, as essential components, plural pairs of ion-selective solid electrodes each pair having two electrodes (one electrode on each of two sides) and each pair having a different ion-selective layer; two liquid distribution porous members, each member disposed over all the electrodes of each said side of the plural pairs; and a porous capillary bridge disposed on or between the liquid distribution porous members. The bridge can be in liquid contact with all the electrodes through the liquid distribution porous members and achieve electrical conduction between two electrodes in each pair after spotting a test solution and a reference solution. The device preferably further comprises a support frame and a cover having two apertures for liquid spotting. The device can simultaneously determine ionic activities of a plurality of different ions in a test solution, such as whole blood, plasma, serum, urine, etc., by spotting a test solution and a reference solution each in one operation and measuring an electrical potential difference of each pair.
