Scanning spectrophotometer LEKI SS2109UV
Scanning spectrophotometer LEKI SS2109UV. Scanning spectrophotometer LEKI SS2109UV is a universal scanning spectrophotometer with a split optical beam. Designed to meet the requirements of pharmacopoeia and analytical practice and is ideal for use in environmental control laboratories, clinical laboratories, production laboratories (process control of raw materials and finished products) and quality control laboratories. The spectrophotometer is included in the State Register of Measuring Instruments under No. 31210-07. Features: Optimized split-beam optical design for maximum precision over a wide wavelength range Large graphic display for spectra, kinetic and calibration curves and splash-proof keyboard Powerful built-in microprocessor allows you to perform all measurements and calculations without connecting to a PC Scanning by wavelength in any selected region of the spectrum Automatic self-monitoring system of all device functions Built-in software with extensive capabilities for collecting and processing experimental data without connecting to a PC, service and control functions Photometric, Scanning, Quantitative, Kinetic, Multi-wave operating modes and DNA determination mode Built-in memory for storing up to 1000 experimental data and calibration curve files Powerful analytical software for connecting to a PC with extensive capabilities for collecting and processing experimental data and numerous service functions is included in the package Large cuvette compartment for mounting cuvettes with optical path length up to 100 mm The outer housing and cuvette compartment are made of chemically resistant engineering plastic The built-in software of the LEKI SS2109UV spectrophotometer implements the following operating modes: main mode (absorption, transmission and measurement of solution concentrations) quantitative mode (creation, saving and use of calibration curves, automatic approximation by curves of 1-3 orders, three correction methods, up to 10 standard solutions) scanning mode (scanning the spectrum of a sample in any selected area with a specified speed and step, scaling and saving spectra, convenient search for spectrum maxima) kinetic mode (automatic measurement of the dependence of absorption (transmission) of solutions on reaction time with a specified interval and delay time, automatic calculation of enzyme concentrations, scaling and saving curves) multi-wave mode (simultaneous measurement of absorption (transmission) of solutions at 2... 10 wavelengths) DNA/proteins (automatic calculation of DNA and protein concentrations, ability to set custom calculation algorithms) setup mode (performs numerous service functions) Analytical software for PCs based on Windows significantly expands the capabilities of collecting and processing experimental data.
