Cartridge for nucleic acid separation and purification and method for producing the same

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 ( 226 a) to an inner side end part ( 226 b). 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.
