Spectrophotometer LEKI SS2107UV
Spectrophotometer LEKI SS2107UV LEKI SS2107UV is a general purpose split beam spectrophotometer. Designed to measure transmittance and optical density of samples of various origins in the visible and UV wavelength ranges. 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: - Optimized split-beam optical design to achieve the highest accuracy over a wide range of wavelengths - Microprocessor control with automatic testing of the optical system when the device is turned on - Informative graphic display for displaying calibration curves and a splash-proof film keyboard - Built-in software for collecting and processing experimental data without connecting to a PC - Photometric, Quantitative, Kinetic operating modes and DNA detection mode - Scanning by wavelength when connected to a PC, software included - Built-in memory for storing up to 1000 files of experimental data and calibration curves - Large cuvette compartment for installing cuvettes with an optical path length of up to 100 mm - External housing and cuvette compartment are made of chemically resistant engineering plastic The built-in software of the LEKI SS2107UV 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) - 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) - DNA/proteins (automatic calculation of DNA concentrations and proteins, the ability to set custom calculation algorithms) - setup mode (performs numerous service functions) Analytical software for a Windows-based PC allows for wavelength scanning mode (scanning the spectrum of a sample in any selected area with a given speed and step, scaling and saving spectra, convenient search for spectrum maxima), and also significantly expands the capabilities of collecting and processing experimental data.
