CGOLDENWALL Visible Spectrophotometer 721G Lab Equipment Wavelength Range:340-1000nm Spectral Bandwidth: 5nm

• This Visible Spectrophotometer adopts a microprogramming technology. It can be used in a material determination, a quantitative analysis in a visible spectrum field. This equipment is a multipurpose analyzer which is necessary for all general labs. It applies to the medical health, clinical examination, biochemistry, petrochemical engineering, environmental protection, quality control’s department and teaching lab of universities and colleges etc..
• Fundamental principles: The spectrophotometer analytical method is based on the different materials’ molecular structure’s selective absorption of electromagnetic radiation..
• The available electromagnetic radiation’s spectral region is normally between 330nm-800nm..
• Main Technical standard: Wavelength Range: 340nm~1000nm.
• Stray light: ≤0.5%(T)(at 360nm ,with NaNO2).

2 Packs Bug Zapper Mosquito Trap Indoor Insect Attractant Trap Lamp Mosquito Killer for Home Indoor

• Double trapping ability, the mosquito killer lamp has 6 ultraviolet lamps, which emit light with a wavelength of 365-395NM, which is very attractive to mosquitoes. The light is used to attract mosquitoes, then the fan sucks them in so they can’t escape..
• Please use it for 3 to 5 consecutive days for the first time. Close the doors and windows during the day to keep the environment dark and put it in the bedroom to kill mosquitoes. When you go nto sleep, move it to the living room to kill mosquitoes (to prevent mosquitoes in the living room from flying into the bedroom). Try to place it at a position about 1 meter above the ground. Do ot turn on the lights, open doors and windows, and do not place it on the air conditioner or fan outlet..
• Turn on the mosquito killer 3 hours before entering the room, do not put it on the bedside or around the human body, because human body temperature and odor will affect the effect of attracting mosquitoes..
• Look at the mosquito storage box after seven days, because the physical mosquito killing method is adopted, and the mosquitoes are killed by air-drying and dehydration. If it is opened frequently, mosquitoes that are not dead will fly out..
• Mosquito killing lamp adopts physical mosquito killing method. Unlike mosqui....
