## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is to provide a guiding device, and more specifically, to a guiding device for guiding a dispenser to draw solution from at least one well on a microplate.
2. Description of the Prior Art
It is general to use a dispenser to draw solution from a well on a microplate for an experiment or a test. However, as putting a pipe of the dispenser in a wrong place, it is easy to draw a specimen and the solution at the same time, resulting in affecting an accuracy of the test. For example, when applying a magnetic specimen which the specimen is attracted with iron powder as a carrier, a magnet is often disposed on a lower side of the microplate to attract the magnetic specimen, and then the dispenser can be operated to draw the solution with an automation testing system or an experimenter by visual inspection. However, the solution may not be drawn in a particular angle without drawing the specimen at the same time in a rapid, accurate, easy and low-cost manner.

The guiding device 58 includes at least one column body 64, and at least one slotting structure 66. Please refer to FIG. 1 to FIG. 6. FIG. 6 is a diagram of the column body 64 and the slotting structure 66 according to the embodiment of the present invention. A first opening 641 and a second opening 643 are formed on two opposite sides of the column body 64. The slotting structure 66 passes through the column body 64 and communicates with the first opening 641 and the second opening 643, the slotting structure 66 can be substantially not parallel to an axial direction of the column body 64.
