UV-VIS Spectrophotometer Manufacturer,Supplier and Exporter in India
Product Code : EL-AS-10474
Jlab Export is a leading UV-VIS Spectrophotometer Manufacturer,and suppliers in India
UV-VIS Spectrophotometer (code EL-AS-10474) is an ultraviolet-visible spectrophotometer that scans spectra, follows kinetic curves and measures the concentration of unknown samples. It has 0.5 nm optical resolution, a choice of four spectral bandwidths and stray light of 0.03%, and can print a report directly. JLab manufactures its double-beam and split-beam versions in Ambala, India.

From Absorbance to Concentration
The instrument passes light of a selected wavelength through the sample and compares it with light that has not been absorbed. Absorbance follows the Beer-Lambert law, A = εcl, where ε is the molar absorptivity of the compound, c its concentration and l the path length of the cell; with ε and l fixed, absorbance rises in proportion to concentration, so an unknown sample can be read against standards. Stray light, meaning light outside the selected band that reaches the detector, limits readings on strongly absorbing samples, which is where the low 0.03% figure counts.
Double-Beam and Split-Beam Designs
In the double-beam design the light is divided between the sample and a reference cell, so a change in lamp output affects both paths and cancels out. In the split-beam design part of the beam goes to a reference detector that tracks the source while the rest passes through the sample. Either way, readings are corrected for changes in lamp output.
Choosing a Spectral Bandwidth
The spectral bandwidth can be set to 0.5, 1, 2 or 4 nm. A narrow bandwidth resolves fine detail in a spectrum, while a wider one lets more light through for a quieter signal. The 7-inch colour screen shows scans and kinetic curves, entry is on a water-proof keyboard, results are stored or printed through USB devices, and PC workstation software adds extended functions.
