Description

TECHNICAL FIELD

[0001] The utility model relates to photochemical experiment technical field, concretely is a headspace irradiation's light reaction test tube. BACKGROUND

[0002] In modern chemistry and biology research, photochemical reactions are of great interest due to their unique reaction mechanisms. These reactions rely on specific wavelengths of light energy to drive chemical changes between molecules, and are widely used in synthetic chemistry, materials science, and biomedical fields.

[0003] To ensure the accuracy and repeatability of photochemical experiments and to be suitable for different reaction temperature conditions, researchers usually use specially designed photochemical reaction test tubes. These test tubes not only need to have good optical transparency to allow light to penetrate effectively, but also need to have heat resistance, chemical stability and mechanical strength to adapt to various complex experimental conditions. Traditional photochemical reaction test tubes are mostly made of glass or high-transparency plastic, and are equipped with sealing caps or plugs to maintain the purity and stability of the internal environment.

[0004] However, in the prior art, in order to solve the potential conflict between the light source device and the temperature control device, some designs choose to integrate an inward irradiation light system on the test tube cap. This design aims to avoid the liquid bath interference problem that may be caused by the traditional side irradiation method by directly mounting the light source on the top of the test tube. Although this method can simplify the experimental setup to some extent, it also brings new challenges. Specifically, since the light irradiation device partially extends into the test tube, it increases the risk of contamination of the reagents - any small particles or impurities attached to the surface of the light irradiation device may fall into the test tube, affecting the sealing of the reaction and the light utilization efficiency, and thus affecting the experimental results. In addition, in order to facilitate the control and adjustment of the position and parameters of the light irradiation device, it is often impossible to achieve complete sealing of the test tube and effective temperature control. Such a non-sealed state not only allows pollutants in the external air to enter, but also causes changes in the pressure difference between the inside and outside of the test tube, ultimately causing an increase in experimental errors and affecting the accuracy of the data. Therefore, developing a novel photochemical reaction test tube that can provide efficient headspace irradiation while ensuring the absolute sealing of the internal environment of the test tube has become a technical problem that needs to be solved urgently.

[0010] Further, the top view area of the light-transmitting hole is less than or equal to the top view area of the light-transmitting sheet.

[0011] Further, the light-transmitting hole is internally provided with a limiting structure, which can limit the movement of the light-transmitting sheet from inside the sealing cover to outside the sealing cover through the light-transmitting hole when the sealing cover is installed on the test tube body.
