Abstract

An exemplary embodiment of the present invention relates to a cuvette of which an inner space thereof is easily cleansed while minimizing its inner space. A cuvette according to an exemplary embodiment of the present invention includes an upper portion having an inlet and forming a first inner space; a middle portion following the first inner space and forming a second inner space that is smaller than the first inner space; and a lower portion following the second inner space and forming a through hole having an interior diameter that is narrower than a cross-section of the second inner space. Accordingly, the through hole functions as a valve to stop the solution when the solution is divided to the inner space for the test, and after the test, the inlet is pressed such that the through hole functions as a nozzle when cleansing such that the solution may be exhausted therefrom.

Dependent claims

A cuvette made of a container used for a spectroscope test of a sample solution, comprising:

an upper portion having an inlet and forming a first inner space of the container;
a middle portion connected to the first inner space and forming a second inner space of the container configured to contain the sample solution;
and
a lower portion having a through hole connected to the second inner space, a horizontal cross-section area of the through hole being narrower than a horizontal cross-section area of the second inner space,
wherein the vertical length of the second inner space is longer than the vertical length of the through hole,
wherein the lower portion and the middle portion have a quadrangle outer shape and the lower portion has substantially the same outer width and outer thickness with the middle portion, and
wherein the horizontal cross-section areas of the second inner space and the through hole respectively have a first dimension and a second dimension, the first dimension of the second inner space is the same to the first dimension of the through hole and the second dimension of the second inner space is greater than the second dimension of the through hole.
