    摘要： An object of the invention is to provide a porous filter cartridge that hardly involves the contamination problem, provides an economic advantage, and is able to achieve efficient filtration and extraction without breaking. The object is accomplished by a porous filter cartridge including a bottomed cylindrical cap 5 with an outlet opening 29 at the bottom and a porous filter held inside the cap 5 on the bottom. At the bottom of the cap 5 a plurality of ribs 35, 37, and 39 are arranged radially about the outlet opening 29 in a standing condition to support the porous filter. At least some of the ribs are connected to each other at the center of the outlet opening 29 to span the outlet opening 29 to form a junction 43. The junction 43 has a top surface 41 convex to the porous filter side.

    摘要： A cartridge for nucleic acid separation and purification and a method for producing the cartridge are provided which does not require a special facility for adhering containers and can produce a number of cartridges at the same time. Also is provided a cartridge for nucleic acid separation and purification in which a washing liquid is prevented from remaining in the container during washing step of nucleic acid separation and purification, and liquids is prevented from attaching to an outer wall surface of a discharge part. Specifically, a cartridge for nucleic acid separation and purification (100) is composed of: an insert member (110) including a bottom member (120) and a nucleic acid-adsorptive porous membrane (F); and a barrel (140) which is formed by insert injection molding with the insert member (110). A rib (226) of the cartridge for nucleic acid separation and purification (200) slopes down to the discharge part (224) in a direction from an outer side end part (226a) to an inner side end part (226b). A thickness (T) at an end face (324), which is a part forming the second opening (321) of the cap (320) of the cartridge for nucleic acid separation and purification (300), is made 0.2 mm or more.

    摘要： Porous membrane cartridge includes: a tubular-shaped barrel member having a weld portion at an outer peripheral surface positioned adjacent to one end thereof; a tubular-shaped cap member having a weld portion, inner peripheral surface of which contacts the weld portion of the barrel member, and a sandwiching surface which faces to an open edge portion of the barrel member-side weld portion; and a porous membrane sandwiched between the open edge portion of the barrel member-side weld portion and the sandwiching surface of the cap member. Porous membrane cartridge is manufactured by inserting the cap member and the porous membrane in a cavity of a mold for injection molding, and thereafter injecting molding material into the cavity to form the barrel member. Cap member-side weld portion has a ratio of its height (H) and its diameter (D), which is defined by H/D, to be equal to or greater than 0.07.
