CENTRIFUGAL ULTRAFILTER UNIT FOR ULTRAFILTRATION OF BIOCHEMICAL SOLUTIONS

摘要

Abstract of the DisclosureA separator (1; 51) including a solution reservoir (3;53) having a solution chamber (3a; 53a) for putting therein asolution, a membrane support base (4; 54) joined to the solu-tion reservoir, an ultrafiltration-oriented filteringmembrane (5; 55) held between the solution reservoir and thesupport base, and a filtrate cup (2) attached to the supportbase, in which the solution reservoir and the support baseare each respectively made of a thermoplastic material,wherein the solution reservoir is ultrasonically welded tothe support base at a part (3b; 53b) thereof spaced apart bya predetermined distance (11; 12) from the filteringmembrane.
