Visible Scanning Spectrophotometer

The first Visible Scanning Spectrophotometer in the range to leverage diode array technology to produce fast results. Covering a wavelength range of 335 to 800nm, with a spectral bandwidth of 7nm, this spectrophotometer is ideal for a variety of applications in education and routine testing in clinical, veterinary, pharmaceutical and QC laboratories.

DIDAC offers measurement modes for single wavelength with basic absorbance and % transmittance; concentration calculated using a standard or a factor; optical density; quantitation with the ability to create a calibration curve using up to 6 standards and 3 replicates; full spectrum scanning and kinetics where up to 3 wavelengths can be measured simultaneously.
