UV-1800

From photometric to protein quantitation:Equipped with a variety of measurement modesas a standard feature1. Photometric ModeMeasures the absorbance or transmittance at a single wavelength ormultiple (up to eight) wavelengths. In multiple-wavelengthmeasurement, calculations can be performed on the data obtainedfor up to four wavelengths, including the calculation of the differencebetween, or ratio of, the measurements obtained for twowavelengths.2. Spectrum ModeA sample spectrum is recorded using wavelength scanning. Repeatscans let you follow sample changes over time. Zoom in on thefinished spectrum for a better view, then use the peak/valley pickfunction to select maxima and minima, and perform a wide variety ofdata processing functions.3. Quantitation ModeGenerates a calibration curve from the measurement of standards,and then calculates the concentrations of unknowns. Allows variouscombinations of wavelength number (1 to 3 wavelengths andderivatives) and calibration curves (K-factor and first-to-third order).12
