Abstract

Föreliggande uppfinning avser en ny filtratprovtagare (100a, 100b) för uppsamling av ett filtratprov från en cellulosalösning. Filtratprovtagaren (100a, 100b) omfattar: en mantel (140a, 140b), en kolvstång (110a, 110b), som omfattar en första ände (111a, 111b) och en andra ände (112a, 112b), vilken kolvstång (110a, 110b) är anordnad in i nämnda mantel (140a, 140b) i mantelns (140a, 140b) längsriktning och en spaltsil (120a, 120b), som är anordnad vid kolvstången (110a, 110b). Spaltsilen (120a, 120b) omfattar ett flertal spalter (123), som sträcker sig i riktningen för kolvstångens (110a, 110b) längsriktning.
