Embodiment

[0019] The concrete structure of the present invention is as Figure 1 ~ Figure 2 shown by Figure 1 ~ Figure 2 It can be seen that the present invention includes a box body 1, and the box body 1 is made of opaque materials such as stainless steel, so as to ensure that the box body is light-tight and prevent ultraviolet light from leaking out and causing harm to the human body. The top in the box body 1 is provided with an ultraviolet light emitting device composed of an ultraviolet light tube 2 and a bracket 3, and the ultraviolet light tube 2 is fixed by the bracket 3; The heat pipe 4 heats the water liquid 5 and maintains a constant temperature; the sample tray includes a square tray body 7, a glass plate 8 and multiple rubber bands 9, and the square tray body 7 is made of stainless steel or enamel, which can resist acid and alkali. The glass plate 8 is placed in the square tray body 7, and the rubber band 9 is circled on the glass plate 8; each sample slide 10 is respecti...

Abstract

The invention discloses a thermostatic water bath UV light irradiator, comprising a light-tight case body; a UV light emitting device is arranged on the top part inside the case body; a baffle plate is fixed in the middle inside the case body and is transversely provided with a through hole, and a heating pipe is arranged under the baffle plate. A sample tray is placed under the UV light emittingdevice and above the baffle plate. The thermostatic water bath UV light irradiator, having the UV light emitting device and the thermostatic water bath device arranged in the same case body, has the advantages of convenient operation, safe use and stable performance.

Description

technical field [0001] The invention relates to an ultraviolet light irradiation instrument, in particular to a constant temperature water bath ultraviolet light irradiation instrument. Background technique [0002] Sister chromatid differentiation (SCD) is a chromosome processing technology developed in the mid-1970s. Sister chromatids have the same chemical composition and structure under normal circumstances, so they cannot be distinguished by simple staining. In 1973, Latt added 5-bromodeoxyuridine (Brdu) to cultured cells. When stained with Hoechst33258 fluorescent dye, he discovered the phenomenon of color difference reflection of sister chromatids and the exchange between them. [0003] In 1974, KO Renberg and Froeed-Lender improved this technique and established a simpler Brdu-Giemsa technique. This technique is used to study a series of important theoretical issues such as cell cycle, chromosome semi-conservative replication, molecular structure and aberration of ...
