Patent ID: 7708881

Claim:
A magnetic bead-based sample separating device, comprising: a body; a first reactor disposed inside the body for receiving a mixing solution at least comprising a plurality of magnetic beads and a sample extraction, wherein the sample extraction is bound with the magnetic beads; a second reactor disposed inside the body for receiving a washing buffer; a third reactor disposed inside the body for receiving an elution buffer, wherein the second reactor is positioned between the first reactor and the third reactor; a first micro-channel disposed inside the body for connecting the first reactor and the second reactor; and a second micro-channel disposed inside the body for connecting the second reactor and the third reactor; wherein the magnetic beads are driven by a magnetic force to move to the second reactor from the first reactor via the first micro-channel for enabling the washing buffer to wash the magnetic beads; wherein the magnetic beads are driven by the magnetic force to move to the third reactor from the second reactor via the second micro-channel for enabling the elution buffer to separate the sample extraction from the magnetic beads.
