Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a rack used for cleaning a cuvette which is a glass, quartz or plastic cell used for an automatic photometer.

[0002]

[Prior art]

 An automatic photometer is a device that automatically performs absorption analysis. Spectrophotometry is an analytical method that utilizes the fact that substances in a solution absorb light. As the concentration increases, the amount of light absorbed increases, so use a photometer to measure the amount of light transmitted through the solution and perform quantitative analysis. In some cases, the quality of a substance in a solution is determined using the property that the wavelength of light absorbed by the substance differs. Since the wavelength of light to be absorbed differs depending on the substance, spectroscopy is required. A spectrophotometer is an analytical instrument that has a device that can continuously change the wavelength of light and a photometer that measures the amount of light. Actual absorption analysis is performed by irradiating a sample solution in a container called a cuvette with light of one or more wavelengths set in advance, and measuring the amount of transmitted light with a photometer. . An automatic photometer is a device that automatically absorbs and analyzes a large number of samples placed in multiple cuvettes. The cuvette is also called a cell and is made of glass, quartz or plastic. In general, there are a transparent and smooth photometric surface and a ground glass or ground glass surface, and accurate measurement cannot be performed if the photometric surface is contaminated. When operating with the cuvette, hold the frosted glass surface so that dirt on fingers does not adhere to the photometric surface. After use, after immersion in cleaning solution or ultrasonic cleaning, wash with water, dry and use repeatedly.

[Problems to be solved by the invention]

 When using an automatic photometer, tens to hundreds of cuvettes are often used for one analysis. Therefore, many cuvettes are cleaned after use, and during ultrasonic cleaning, they are put together and placed in one container. As a result, the cuvette was cracked or the photometric surface overlapped with the surface, and cleaning was not performed well. In addition, it was time-consuming to set the equipment after cleaning since it was put in containers separately. In addition, it was troublesome to rearrange them during storage after drying, or they were stored in pieces. The present invention has been made in view of such problems of the prior art, and solves the above-mentioned disadvantages or inconveniences, does not break or overlap during cleaning, and is easy to set in equipment. Its primary purpose is to provide a cuvette cleaning rack. More specifically, holes provided in a mat made of a plastic material can support the cuvettes while providing a washing space on the photometric surface, and each rack can be stacked while supporting the cuvettes. It is intended to provide a cuvette cleaning rack.

[0004]

[Means to solve the problem]

 In order to achieve the above object, the present invention provides a mat made of a plastic material provided with holes and a ceramic material used for cleaning a cuvette which is a glass, quartz or plastic cell used for an automatic photometer. In a rack made of metal, paper, or plastic frames, the cuvette can be supported by providing holes on the mat made of a plastic material while providing a washing space on the photometric surface. The rack can be stacked while supporting the cuvette.

[Embodiment of the invention]

As the plastic material used for the mat, various foams such as sponge-like silicon, urethane, and PS, and various rubbers can be considered, and silicone rubber having various resistances and flexibility is most suitable. The material of the frame is metal, such as stainless steel, steel, titanium, aluminum, etc., polycarbonate, polypropylene, which can be sterilized by high pressure steam, plastic such as ABS and polyacetal, porcelain such as ceramic, ceramics, glass, and water resistant treatment. Torn paper is conceivable. Depending on the material, injection molding and assembly can be considered for the production of the frame. A cuvette cleaning rack composed of a silicone rubber mat and a stainless steel frame was manufactured. The cuvette was firmly supported by the silicone rubber mat, did not fall off during cleaning, and a cleaning space was provided on the photometric surface, so that cleaning was possible. In addition, since they are individually arranged in order, it is easy to set them in an automatic photometer after washing. Furthermore, the cuvettes, which have been washed and dried and stored on a mat, can be stacked as they are, so they are orderly and have no cracks.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail. A silicone rubber mat was placed on a stainless steel frame to make a cuvette cleaning rack. The stainless steel frame was provided with a frame around the inside to put a silicone mat on, a support was also provided in the center, and a stainless steel mesh was set up at the bottom. The stainless steel net at the bottom may be a punched stainless steel plate having a plurality of holes formed in a stainless steel plate. A plurality of cuvette setting holes for inserting and fixing a plurality of cuvettes were alternately provided in the silicone rubber mat. The cuvette setting holes are provided alternately so that when the cuvette is inserted, the swelling of the hole does not easily affect the adjacent hole. Also, a mat holding plate was provided between the cuvette setting hole on the silicone rubber mat and the cuvette setting hole so that the mat did not rise when the cuvette was pulled out. The cuvette setting hole was 0.1 mm to 0.5 mm smaller than the cuvette diameter on one side, and larger than the cuvette diameter on one side. . As a result, a space for cleaning was formed on the photometric surface, and the cleaning liquid, water, and the like could be thoroughly washed at the time of cleaning. In addition, by making one side smaller than the diameter, the cuvette could be firmly supported and did not fall off during washing. Furthermore, since the cuvettes are individually arranged in order in the same direction, it has become easier to set the cuvettes on the automatic photometer after washing. Furthermore, the cuvettes, which have been washed and dried and stored on a mat, can be stacked as they are, so they are orderly and do not break.

(Example 1) Using a stainless steel plate having a thickness of 1 mm, a 10 mm wide frame is provided at a height of 144 mm, a width of 179 mm, a height of 22 mm, and an inner height of 15 mm for mounting a silicon mat. A 10 mm wide support is also provided at the center, a stainless steel net 6 with a mesh size of about 2 mm square is attached to the bottom, and each of the four corners of the frame is 10 mm long from the corner, a height of 7 mm and a stainless steel frame. A stainless steel frame 3 as shown in FIG. 2 provided with the stacking guide 5 so as to be 3 mm higher than the upper side was produced. Next, on a silicone rubber mat having a thickness of 7 mm, a length of 145 mm and a width of 175 mm, a height of 5 mm. A rectangular cuvette setting hole having a width of 7 mm and a width of 15 mm was set at an interval of 10 mm, and a cuvette setting silicon rubber mat 2 was prepared in which 50 rows were formed so that each row was alternated. The silicon rubber mat 2 for cuvette installation was placed on a stainless steel frame 3, and three silicon rubber mat pressing plates 4 each having a width of 3 mm were provided between the cuvette installation holes using stainless steel as shown in FIG. A cuvette washing rack was prepared. A cuvette 7 having a length of 6 mm and a width of 8 mm as shown in FIG. 3 is set in this cuvette washing rack such that the photometric surface 8 is located on the side of the washing space 10 as shown in FIG. After washing, the cuvette setting hole 1 on the side of the frosted glass surface 9 of the cuvette 7 is 0.3 mm shorter, so that the cuvette is firmly supported without falling off, the cuvette is not broken, and photometry is performed. The cleaning liquid and water spread into the cleaning space 10 between the surface and the silicone rubber mat, and the cleaning was performed efficiently. When the cuvettes 7 were set on the automatic photometer after washing, the cuvettes 7 could be easily set because they were individually arranged in the same direction and in order. Further, as shown in FIG. 6, cuvettes in which the storage after washing and drying are arranged on a mat can be stacked as shown in FIG. 6, so that the cuvettes are orderly and do not break. Further, since the stacking guides 5 are provided at the four corners, the stacking is stable and does not slip off when stacked.
