Double Beam Spectrophotometer - (UV 3200)


The two detectors measure sample and reference respectively and simultaneously for optimizing measurement accuracy. They provide excellent performance for measurements in the range of 190 to 1100nm. They are suitable for pharmaceutical, biochemical and clinical lab applications as well as routine applications such as quantitative analysis, kinetics, wavelength scan, multiple components and DNA/Protein, PC Windows application software make these instruments versatile.


» Variable slits (bandwidths)
» For Stand-alone instrument, all software methods are included as built-in standard; this eliminates the need of software.
» Online software upgrade via internet helps to keep it updated.
» Data Download-to-PC software expands the data storage to unlimited.
