A nucleic acid extracting device includes a reagent containing unit, a mixing unit, and a flow channel unit. The reagent containing unit contains a specimen, a magnetic bead, and a reagent for extracting. The mixing unit includes a mixing chamber and a stirring assembly. The mixing chamber includes a chamber portion and a tube portion. The stirring assembly includes a main body and an extension. The main body is provided in the chamber portion. The tube portion connects the chamber portion. And the extension connects the main body and extends into the tube portion. The extension and an inner wall of the tube portion have first and second gaps therebetween respectively along first and second directions of the tube portion. The first gap is less than the second gap. The flow channel unit is connected between the reagent containing unit and the mixing unit.

A blender tool is disclosed for assisting in blending a substance within a blender. The blending tool comprises a primary body and a secondary body. A handle is coupled to the primary body. The primary body and the secondary body slidably engage for defining a telescoping engagement. The telescoping engagement provides a varying tool length. A slip nut engages the telescoping engagement for coupling the primary body to the secondary body and defining a fixed tool length. An appendage is coupled to the secondary body for increasing the contact surface area between the secondary body and the substance and improving the blending of the substance within the blender container. The varying tool length is configured for maintaining a separation between the secondary body and the mixing blade.
