Abstract

The present invention discloses a guiding device for guiding a dispenser to draw solution from at least one well on a microplate. The guiding device includes a column body whereon a first opening and a second opening are formed on opposite sides, and a slotting structure passing through the column body and communicating with the first opening and the second opening. A pipe of the dispenser passes through the first opening, the slotting structure and the second opening to reach inside the at least one well on the microplate for drawing the solution contained in the at least one well.

First claim

What is claimed is:

1. A testing system comprising:
a microplate, whereon a plurality of wells are formed for containing solution and magnetic specimens;
at least one magnetic component disposed on a side of the microplate for attracting the magnetic specimens contained in the plurality of wells;
a dispenser comprising at least one pipe for drawing solution contained in the plurality of wells; and
a guiding device for guiding the at least one pipe of the dispenser to draw solution from the plurality of wells on the microplate, the guiding device comprising:
at least one column body, a first opening and a second opening being formed on opposite sides of each column body; and
at least one passageway structure passing through the corresponding column body and communicating with the corresponding first opening and the corresponding second opening, and the at least one pipe of the dispenser passing through the corresponding first opening, the at least one passageway structure and the corresponding second opening to reach inside a corresponding one of the plurality of wells on the microplate for drawing the solution contained in the corresponding one of the plurality of wells and for preventing drawing the magnetic specimens contained in the corresponding one of the plurality of wells.

2. The testing system of claim 1 , wherein the at least one passageway structure is substantially not parallel to an axial direction of the at least one column body.

3. The testing system of claim 1 , wherein the at least one column body is inserted in the corresponding one of the plurality of wells on the microplate.

4. The testing system of claim 3 , wherein the guiding device further comprises a plurality of column bodies for selectively inserting in the plurality of wells.

5. The testing system of claim 1 , wherein the guiding device further comprises a guiding plate whereon a plurality of holes are formed, the at least one column body is detachably disposed in a corresponding one of the plurality of holes, and the guiding plate is installed on the microplate.

6. The testing system of claim 5 , wherein a constraining portion is formed in each hole on the guiding plate, the at least one column body comprises an engaging portion for engaging with the corresponding constraining portion so as to constrain a rotation of the at least one column body in the corresponding one of the plurality of holes on the guiding plate.

7. The testing system of claim 5 , wherein the guiding device comprises a plurality of column bodies for selectively inserting in the plurality of holes.

8. The testing system of claim 1 , wherein the guiding device further comprises a guiding plate whereon a plurality of holes are formed, the at least one column body is fixed in a corresponding one of the plurality of holes on the guiding plate, and the guiding plate is installed on the microplate.

9. The testing system of claim 8 , wherein the guiding device comprises a plurality of column bodies being selectively fixed in the plurality of holes.

10. The testing system of claim 1 , wherein the guiding device comprises a plurality of column bodies separated from or connected with each other.
