Spectrophotometer LEKI SS2107
Spectrophotometer LEKI SS2107. Spectrophotometer LEKI SS2107 is a universal single-beam spectrophotometer for general purpose. Designed to measure transmittance and optical density of samples of various origins in the visible wavelength range. The device is designed taking into account all the requirements of analytical practice and is used in environmental control laboratories, production laboratories in various industries (technological control of raw materials and finished products), qualitative and quantitative analysis in educational and scientific laboratories. The spectrophotometer is included in the State Register of Measuring Instruments under No. 31210-07. Features: Electronic wavelength setting Microprocessor control with automatic testing of the optical system when the device is turned on Informative graphic display for displaying calibration curves and splash-proof membrane keyboard Simultaneously display concentration, absorbance, transmittance and wavelength Built-in software for performing photometric quantitative analysis techniques without connecting to a PC Scanning by wavelength, multi-wave and kinetic modes when connected to a PC, software included in delivery Built-in memory for storing up to 200 measurement methods and experimental data Large cuvette compartment for installing cuvettes with an optical path length of up to 100 mm and additional attachments The outer housing and cuvette compartment are made of chemically resistant engineering plastic Analytical software for PC based on Windows significantly expands the capabilities of collecting and processing experimental data and implements the following operating modes: photometric mode (absorption and transmission of samples) quantitative mode (creation, saving and use of calibration curves, automatic approximation with 1st and 2nd order curves, up to 20 standard solutions) kinetic mode (automatic measurement of the dependence of absorption and transmission of solutions on reaction time with a specified interval and delay time, scaling and saving curves) wavelength scanning mode (scanning the sample spectrum in any selected area with a given step, scaling and saving spectra, calculations and taking derivatives, convenient search for spectrum maxima) multi-wave mode (simultaneous measurement of absorption or transmission of solutions at 2 ... 15 wavelengths) Manba: https://www.nv-lab.ru/catalog_info.php?ID=1239
