Spectrophotometers

Product Details:

Spectrophotometer is commonly used for measuring transmittance or reflectance of solutions, transparent or opaque solids like polished glass or gases. These can also be designed for measuring diffusivity on any of listed light ranges that normally covers around 200nm - 2500nm through use of different controls and calibrations. Within these ranges of light, calibration is required on machine using standards which vary in type depending on wavelength of photometric determination, The range offered includes Atomic Absorption Spectrophotometer, Microprocessor UV/Double Beam Spectrophotometer and Single/Double Beam Microprocessor Spectrophotometer. Here, while offering the solutions we also ensure that these are the best available choices made available in the market.

Product Details:

Microprocessor UV/Double Beam Spectrophotometer has a range from 190-1100 nm and come with features like wavelength scan, DNA Protein Test/Kinetic, automatic peak picking and spectrum display. Further, it also has large screen with graphic display with option of spectrum & data to be printed out by printer as well as sent to computer via USB PORT. Other than this, a set of 4 quartz & 4 glass cuvettes and software are also provided is provided. As an advanced Double Beam UV-VIS Spectrophotometer, it delivers more accuracy as well as flexibility in usage. The operations include use of two detectors for measuring sample & reference simultaneously for getting accurate measurement. Further, it has wide wavelength range that meets the usage requirements in different fields like -
