Dual beam scanning spectrophotometer LEKI SS2110UV
Dual beam scanning spectrophotometer LEKI SS2110UV Scanning spectrophotometer LEKI SS2110UV is a universal dual-beam scanning spectrophotometer. 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 dual-beam optical design for unrivaled precision across the entire wavelength range Powerful microprocessor and embedded software with extensive capabilities for collecting and processing experimental data without connecting to a PC, service and control functions Automatic self-monitoring system of all device functions Large graphic display for displaying spectra, kinetic and calibration curves without connecting to a PC Scanning by wavelength in any selected region of the spectrum Photometric, Scanning, Quantitative, Kinetic, Multi-wave operating modes and DNA determination mode Non-volatile 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 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 SS2110UV 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 (carries out numerous service functions and monitors the metrological characteristics of the device) Analytical software for PCs based on Windows significantly expands the capabilities of collecting and processing experimental data.
