Description

Technical Field

[0001] The utility model relates to the technical field of general sample holders for photometers, and particularly to a general sample holder for a spectrophotometer. Background Technique

[0002] A spectrophotometer, also known as a spectrometer, is a scientific instrument that decomposes light with complex components into spectral lines. It is a conventional instrument in modern laboratories and is often used for nucleic acid and protein quantification as well as the quantification of bacterial growth concentration. In the field of printing and dyeing, we can use a spectrophotometer to measure the dye uptake percentage during dyeing and the concentration of auxiliaries on the fabric, and it can also be used for color measurement. At the same time, it is widely used in food testing, pesticide testing, and petroleum testing in industry, etc. Usually, a cuvette is used as the sample chamber mainly for placing samples. For example, in the Chinese utility model patent with the patent number CN213301994U, a multi-well sample holder for a spectrophotometer includes a bottom plate and a sample holder body located on the bottom plate and integrally formed with the bottom plate. The sample holder body is provided with two rows of sample slots for accommodating cuvettes. Through holes are provided on both sides of the sample holder body, and an arc-shaped elastic piece is arranged on the outer side wall of each sample slot. The arc-shaped elastic piece is made of the same material as the sample holder body and is integrally formed, thus forming a spectrophotometer sample holder with a simple structure that does not require additional fixing of metal elastic pieces. Moreover, this sample holder can be disassembled and installed from above, and maintenance does not require debugging.

[0003] However, there are still some problems in the use of the above device. The sample slots on the sample holder are arranged in parallel, and the number of samples that can be accommodated is limited. When a large number of samples need to be detected, a large amount of space is required to place multiple sample holders, occupying a large space in the laboratory and making it inconvenient for laboratory personnel to take and place samples. Content of the Utility Model

[0004] According to the above existing technical problems, the utility model provides a general sample holder for a spectrophotometer, which is characterized by consisting of a base, a rotating shaft, a tray, label slots, and fixing devices. The rotating shaft is installed above the base, the tray is installed above the rotating shaft, several label slots are installed above the tray, and the fixing devices are respectively installed on the sides of the label slots.

[0005] The fixing device consists of a U-shaped fixing groove, side support rod A, side support rod B, slideway A, slideway B, sliding shaft, slider A, slider B, rotating sleeve, cover plate, chute, and stop block. The U-shaped fixing groove is installed on the side of the label slot. A chute is installed on one side of the open end of the U-shaped fixing groove, and a stop block is installed inside the chute. On the back side of one side of the U-shaped fixing groove, side support rod A is installed, and a slideway A is opened inside side support rod A, and slider A is installed inside slideway A. On the back side of the other side of the U-shaped fixing groove, side support rod B is installed, and a slideway B is opened inside side support rod B, and slider B is installed inside slideway B. A sliding shaft is installed inside slider A and slider B, and a rotating sleeve is installed outside the sliding shaft. A cover plate is installed on one side of the rotating sleeve.

[0006] Advantages of the present utility model:

[0007] A general sample holder for a spectrophotometer of the present utility model is provided with a circular tray, and a number of fixing devices are provided on the tray. Using a circular tray to replace the rectangular bracket-shaped setting can make full use of space, and more samples can be placed when occupying the same area. In addition, a rotating shaft is provided, and the tray can rotate. When an experimenter takes or places a sample, the tray can be rotated. At the same time, a label slot is provided, and a staff member can place a sample label on the label slot, which is convenient for sample distinction. Description of the drawings
