ZF-1 type three ultraviolet analyzer UV lamp quartz glass UV lamp and filter composed of two light wavelengths were 254nm and 365nm. Light through a color filter can be used for experiments, two light sources can be used alone or both simultaneously mixed. First, use: 1, it is a scientific experiment to detect various substances such as proteins, nucleotides and other necessary equipment. 2, in drug production and research, biomass can be used to check hormone base, vitamins and other drugs can produce the quality of fluorescence, which is particularly suitable for thin layer chromatography, paper layer analysis and detection spots. 3, in the dye coating, rubber, oil and other chemical industries, measuring a variety of fluorescent materials, fluorescent indicator and additives, to identify different types of crude oil and rubber products. 4, in the textile and chemical fiber can be used to measure different kinds of raw materials such as wool, silk, rayon, cotton, synthetic fibers and check product quality. 5, grain, vegetables, food sector can be used to check the quality of toxins (such as aflatoxin, etc.), food additives, spoiled vegetables, fruits, chocolate, fat, honey, sugar, eggs and the like. 6, can also be used to prove the identification of public security departments. Second, the instrument structure: This instrument uses wavelengths of 254nm, 365nm of quartz UV lamp and filter composed of a group. For chromatography plate spotting, positioning the lighting, is also equipped with an ordinary fluorescent lamps inside here. The whole structure is simple, lightweight, parts versatility, easy use and maintenance. Third, the technical performance: 1, UV wavelength: 254nm, 365nm 2, UV filter size: 50mm × 200mm 3, Power: AC220V ± 10% 50Hz; lamp tube voltage: 50V ± 10V 4, instrument power: 24w; Instrument Weight: 3.7Kg Fourth, the use and precautions: 1, connect the power, open the "On / Off" light bulb, can be detected by observing and analyzing the samples on the lamp, if the instrument is placed in a dark room or completely obscure the light with a black cloth, the better. 2, UV filter and metal objects can not grazing, not by force, the surface should be kept clean and dry, and so should always wipe with alcohol or ether, anti-mildew filter. 3, when the operator uses, should be aligned samples of ultraviolet radiation, avoid exposure to the human body, it is best to wear glasses, so as not to cause injury.
