Abstract

Disclosed is an apparatus for quantitively supplying a high-viscosity fluid sample, the apparatus including a cylinder body in which a high-viscosity fluid is to be stored, a cylinder head detachably attached to the cylinder body, a piston configured to slide in a longitudinal direction of the cylinder body, and a cutter disposed below the cylinder head and configured to cut a high-viscosity fluid discharged from the cylinder head.

First claim

What is claimed is:

1. An apparatus for quantitively supplying a high-viscosity fluid sample, the apparatus comprising:
a cylinder body in which a high-viscosity fluid is to be stored;
a cylinder head detachably attached to the cylinder body;
a piston configured to slide in a longitudinal direction of the cylinder body;
a cutter disposed below the cylinder head and configured to cut a high-viscosity fluid discharged from the cylinder head; and
a cooler configured to cool the high-viscosity fluid discharged from the cylinder head.

2. The apparatus of claim 1 , wherein the cutter comprises:
a plurality of blades configured to cut the high-viscosity fluid in a direction orthogonal to a direction in which the high-viscosity fluid is discharged; and
an operation lever configured to operate the plurality of blades.

3. The apparatus of claim 2 , wherein the plurality of blades is configured to approach a central axis of the cylinder head while rotating about the central axis.

4. The apparatus of claim 1 , further comprising:
support columns disposed on both sides of the cylinder body; and
fixers penetrating the support columns to fix the cylinder body by pressing both sides of the cylinder body.

5. The apparatus of claim 4 , wherein each of the support columns comprises a guide formed in a direction perpendicular to a ground, and
the fixers are each configured to slide along the guide.

6. The apparatus of claim 5 , wherein the cutter is disposed below the cylinder head, and
the cylinder head is configured to move downward to reach the cutter.

7. The apparatus of claim 1 , wherein the cylinder body comprises:
a first portion having a columnar shape and comprising two planar portions facing each other; and
a second portion having a cylindrical shape and being connected to the first portion.

8. The apparatus of claim 7 , wherein the second portion and the cylinder head are threadedly engageable with each other.

9. The apparatus of claim 1 , wherein the piston comprises an indicator configured to indicate an amount of high-viscosity fluid in the cylinder body.

10. The apparatus of claim 1 , wherein the cooler comprises a cooling box disposed between the cylinder head and the cutter.

11. The apparatus of claim 1 , wherein the cooler comprises a cooling hose configured to enclose the cylinder head.

12. An apparatus for quantitively supplying a high-viscosity fluid sample, the apparatus comprising:
a cylinder body in which a high-viscosity fluid is to be stored;
a cylinder head detachably attached to the cylinder body;
a piston configured to slide in a longitudinal direction of the cylinder body; and
a cooler disposed below the cylinder head and configured to cool a high-viscosity fluid discharged from the cylinder head.

13. The apparatus of claim 12 , wherein the cooler comprises a cooling box disposed between the cylinder head and the cutter.

14. The apparatus of claim 12 , wherein the cooler comprises a cooling hose configured to enclose the cylinder head.
