To measure the Absorbance and transmittance

UV-VIS Double Beam Spectrophotometer
  • Coefficient Method.
  • Standard Curve Up to 10 Standard sample may be used to establish a curve. Four methods for fitting a curve through the calibration points : (Linear fit, Linear fit through zero, Square fit and cubic fit)
UV-VIS Double Beam Spectrophotometer
DNA/Protein Test

Concentration and DNA purity are quickly and easily calculated: Absorbance rations: 260 nm / 280 nm with optional subtracted absorbance at 320 nm. DNA concentration = 62.9XA260-36.0XA280 Protein concentration = 1552xA260-757.3xA 280

UV-VIS Double Beam Spectrophotometer
Wavelength Scan
  • The wavelength scan intervals are 0.1,0.2,0.5,1,2,5 nm
  • High Medium and low scan speed are available. They vary from 100 to 3600 nm/min
  • Wavelength are scanned from high to low so that the instrument waits at high wavelength and it minimizes the degradation of UV sensitive samples.
