Description

Test tube rack with illumination function

Technical Field

The present utility model relates to a test tube rack, and more particularly, to a test tube rack having an illumination function.

Background

The test tube rack is a basic chemical experimental instrument and can be used for placing and airing test tubes in the chemical experimental process. In particular, in chemical experiments in which it is necessary to observe changes in the medium, it is necessary to place a test tube containing the medium on a test tube rack so as to observe changes in the medium at regular time. In the field of medical detection, it is also often necessary to place a test tube with a sample collected on a test tube rack for sampling detection. In order to be able to see clearly the sample deposit etc. in the test tube, it is often necessary to use light, and therefore test tube racks with illumination function have been proposed.

For example, chinese patent application CN205868341U discloses a double-row test tube rack with lighting function, wherein an upper support plate and a lower support plate are provided between the left and right brackets, two rows of test tube holes are provided on each support plate, and a light source is further provided on the inner sides of the left and right brackets to provide lighting function. By utilizing the double-row test tube rack with the lighting function, test tubes do not need to be taken out from the test tube rack, a tester can conveniently observe the change in the test tubes, and the test tubes needing to be compared can be more conveniently compared, so that the sample change in the comparison test tubes can be intuitively observed.

However, the tube rack disclosed in the above patent document is not suitable for strip sampling of an ultracentrifuge tube. This is because, on the one hand, the light-emitting sources are disposed inside the left and right brackets instead of below the test tube, and thus it is inconvenient to observe the band information in the test tube. On the other hand, when sampling a plurality of test tubes, the strips in the test tubes interfere with each other, which results in indistinguishable test staff. Moreover, after the syringe is adopted to transversely insert the needle to take the strip in the test process, a tester is required to hold the test tube to pour the upper layer strip, the syringe cannot be pulled out of the centrifuge tube during the test process so as to prevent liquid from flowing out, and the test tube rack cannot complete the operation.
