Operating protocol, 1pcs | | | | Main testing interface: | Upgraded SP-2102UVP UV-Vis spectrophotometer uses 6.4 inch graphic type LCD with large screen that substitutes previous simple display mode of character type in which new functions, such as spectral scanning, quantitative analysis, ect. are included. The sample’s absorbance, transmittance, or concentration is real-time recorded. The spectral scanning
curve and standard curve can be drawn, and the testing parameters can be shown in list, for example, the wavelength, light source energy, on-off status of the light source, operating suggestions, and so on. The human design fits
the operating custom of most users.
SP-2102UVP UV-Vis spectrophotometer supplies diversified testing mode, mainly about:
Photometric analysis: absorbance, transmittance, concentration measurement.
Quantitative analysis: measurement with slope and intercept (C=K* Abs. + B), measurement with standard curve.
Spectral scanning: whole wavelength range scanning, section of the wavelength range scanning, peak and valley identifying can be carried out.
Main menu: The interface is clear and intuitionistic designed, and with
function key suggests, user can easily enter into appointed interface. | | | | Accessories for choice: | Electronic constant temperature cells holder

AC-220 type intelligent auto-sample controller
AC-210 type intelligent temperature controller | | | | Quantitative analysis: | By inputting the standards' concentration and measuring eachabsorbance, user can easily establish a fitted curve of 10 standards. The system automatically numbers and lists each sample’s absorbance and concentration. User can pick
up the figure of standard curve, linear equation, and correlative coefficient the system automatically calculated, and evaluate the curve’s linear fitting effect. The established standard curves can be stored, printed out or recalled from memory for measuring unknown samples. Moreover, user can directly input the fitted parameters, such as the slope, intercept, etc, to quickly establish standard curve without inputting the concentration values of standard samples. | | | | Note: There may not be special notifications when the technical specification,profile and configuration changed. Please, the products will be in agreement with the real models. |
