More Information
Summary:A nucleic acid extracting device (100) includes a reagent containing unit (110), a mixing unit (120), and a flow channel unit (130). The reagent containing unit (110) contains a specimen, a magnetic bead, and a reagent for extracting. The mixing unit (120) includes a mixing chamber (122) and a stirring assembly (124). The mixing chamber (122) includes a chamber portion (1221) and a tube portion (1222). The stirring assembly (124) includes a main body (1241) and an extension (1242). The main body (1241) is provided in the chamber portion (1221). The tube portion (1222) connects the chamber portion (1221). And the extension (1242) connects the main body (1241) and extends into the tube portion (1222). The extension (1242) and an inner wall of the tube portion (1222) have a first gap (G1) and a second gap (G2) therebetween respectively along a first direction (RD1) and a second direction (RD2) of the tube portion (1222). The first gap (G1) is less than the second gap (G2). The flow channel unit (130) is connected between the reagent containing unit (110) and the mixing unit (120).
