A fluidic device is provided for sealing a proper amount of fluid with a brittle material. By moving an adsorbate through an external adsorption force, the brittle material for pre-sealing is broken, and the fluid flows out to interact with the external environment to generate a pump reaction. In addition, the invention may also be used for storing a liquid reagent in a device for a long time. Thereby, the fluidic device can be made small and portable.

Fluidic device

A magnetic separation device, comprising: at least a test tube base, for receiving at least a test tube; and a magnetic member, pivotally connected to the at least one test tube base and capable of generating a magnetic force. With the aforesaid device, the test tube being received in the test tube base can be moved toward/away from the magnetic member while the magnetic member and the test tube base are driven to rotate about a pivotal end connecting the two, and thereby, the strength of the magnetic force applied on a mixture containing in the test tube by the magnetic member is varied accordingly.

Magnetic separation device

A magnetic separation device, comprising: a separator, including a top base and a bottom base; at least a groove set, each composed of two arc-like grooves having curvatures opposite to each other; at least a magnetic member, being movably fitted inside the two arc-like grooves of the at least one groove set; and at least a test tube slot, each being formed at the outer rim of a base selected from the group consisting of the top and the bottom base of the separator; wherein the top and the bottom bases are assembled by means of a pivotal axis piecing through about at the center of the top and the bottom bases for enabling the two bases to rotate relative to each other; and one of the two arc-like groove is formed on the top base at a surface thereof facing toward the bottom base while forming another arc-like groove on the bottom base at a surface thereof facing toward the top base. With the aforesaid device, the magnetic member can be driven to slide inside the groove set while the top and the bottom bases are driven to rotate relative to each other, thereby, the magnetic member can be moved between two positions whereas one is near the test tube slot and the other is away from the same.
