Abstract

PURPOSE:To easily and inexpensively produce the dry bath having square hous ing chambers by fixing plural square cylindrical members thereby constituting a cuvette housing section. CONSTITUTION:The cuvette housing section 2 is integrally fixed with the square cylindrical members 3 consisting of an aluminum alloy as the side walls 4 there of are adhered to each other to constitute 5 lines and 5 rows. A bottom plate 5 likewise consisting of the aluminum alloy is fixed to the base of the square cylindrical members 3. Sample solns. and reagents are charged into the cuvettes 6 and are then stirred to form solns. 7 to be analyzed. These cuvettes 3 are inserted into the housing chambers 8 of the members 3. The reaction is progressed by heating the cuvettes with the bottom plate 5 and the side walls 4 via a heating member. The cuvettes are then taken out of the housing chambers 8 and the mounted to a measuring instrument, by which the solns. are analyzed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dry path for heating a solution to be analyzed in colorimetric analysis, fluorescence analysis, and the like.

[Conventional technology]

Conventionally, in colorimetric analysis, fluorescence analysis, etc., a sample solution and a reagent are placed in a test tube to form an analyte solution. next,
The test tube containing this solution to be analyzed is attached to a dry path, and the test tube is heated with a dry gas to allow the reaction of the solution to be analyzed to proceed. After the reaction of the analyte solution has sufficiently progressed, the test tube is taken out and the analyte solution is transferred to a cuvette, which is attached to a measuring instrument such as a cuberatra colorimeter or fluorometer for analysis.

[Problem that the invention seeks to solve]

However, in the conventional analysis method described above, a test tube is used during the reaction and a cuvette is used during the analysis, which requires the work of transferring the analyte solution from the test tube to the cuvette, resulting in poor workability. .

Therefore, the present inventors have developed an analysis method that uses a cuvette even during the reaction, eliminates the need to transfer the solution to be analyzed, and allows for efficient analysis.

That is, a sample solution and reagent are placed in a cuvette, and the cuvette is placed in a dry path and heated, but this dry path must have a large number of rectangular storage chambers in order to accommodate the cuvettes.

By the way, since the conventional dry path is for accommodating test tubes, a large number of circular accommodating chambers are formed therein. Dry buses like this were made by drilling holes into a block of metal.

However, the dry lotus used in the analysis method developed by the present inventor requires a rectangular storage chamber;
If it were attempted to form a storage chamber by cutting a metal block as in the past, the work would be extremely troublesome and expensive.

An object of the present invention is to provide a dry lotus that can be manufactured at low cost for use in an analytical method newly developed by the inventor.

[Means for solving the problems] The present invention has been made to achieve the above objects, and
It is constructed by fixing together a plurality of rectangular tube members that are previously formed into a square tube shape.

That is, the dry path of the present invention is characterized in that the cuvette accommodating portion is constituted by a plurality of rectangular tube members whose side walls are fixed to each other.

The cuvette accommodating section is for accommodating and heating cuvettes, and is provided with a plurality of rectangular accommodating chambers.

The rectangular tube member may have a rectangular tube shape with a hollow portion large enough to accommodate a cuvette and be heat resistant, and the manufacturing method thereof is not limited. Further, if the rectangular tube member is open at one end, the other end may be closed. This rectangular tube member is preferably manufactured by manufacturing a long tube and then cutting it at predetermined intervals because it is inexpensive.

[Effect]

In the dry lotus of the present invention, since the cuvette accommodating portion of the dry lotus is composed of a plurality of rectangular tube members, the storage chamber of the cuvette storage portion can be easily formed by forming the rectangular tube members and then fixing them. can.

〔Example〕

An embodiment of the dry pass according to the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a plan view of the dry lotus, and FIG. 2 is a partially cutaway perspective view of the same cuvette housing section.

In FIG. 1, reference numeral 1 indicates an operating section in which switches, temperature adjustment dials, etc. are provided, and reference numeral 2 indicates a cuvette accommodating section for accommodating cuvettes.

As shown in FIG. 2, the cuvette accommodating portion 2 includes a rectangular tube member 3 made of an aluminum alloy with a side wall 4.
are glued together and fixed together in 5 rows and 5 columns.

A bottom plate 5 made of aluminum alloy is similarly fixed to the bottom surface of these rectangular tube members 3.

Note that a heating member (not shown) having a built-in heater is provided on the lower surface of the bottom plate 5.

In the dry pass as described above, a sample solution and a reagent are placed in a cuvette 6 and stirred to form an analyte solution 7, and this cuvette 6 is inserted into the storage chamber 8 of the rectangular tube member 3. Then, the bottom plate 5 and the side walls 4 are heated via the heating member to advance the reaction of the solution to be analyzed 7.

After the reaction of the solution to be analyzed 7 has sufficiently progressed, the storage chamber 8
Take it out, attach it to a measuring device, and analyze it.

Next, a method for manufacturing the cuvette storage section 2 of the dry path will be explained.

First, as shown in FIG. 3, a rectangular long tube material 10 made of aluminum alloy is manufactured.
A large number of rectangular tube members 3 are manufactured by sequentially cutting 0 at predetermined intervals (indicated by broken lines in the figure). Then, the side walls 4 of these rectangular tube members 10 are adhered to each other and fixed together in 5 rows and 5 columns. Furthermore, the bottom plate 5 is fixed to one end surface of the rectangular tube member 10 fixed integrally, thereby completing the cuvette storage section 2.

〔Effect of the invention〕

According to the present invention, by fixing a plurality of rectangular tube members to form a cuvette storage section, a dry path having a rectangular storage chamber, which has not existed in the past, can be manufactured extremely easily and at low cost.
