Description: Visible Spectrophotometer VS721G Visible Spectrophotometer VS721G Brand NEW Description: This product 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. Characteristics:The monochromator with a holographic flashing grating is used. It has the advantage of high wavelength precision, good monochromaticity and low stray light.Automatic switching of tungsten halogen lamp and deuterium lamp.A sample compartment for 0.5cm-10cm cells.Computer control system, precise automatic T/A changeover.Automatic zero and full scale adjustment.Direct concentration read-out and concentration factor setting function.Equipped with RS232 port.
