Spectrophotometer SF-2000 (190...1100 nm)
Spectrophotometer SF-2000 designed for measuring the spectral coefficients of directional transmittance of liquid and solid transparent samples and is used in sanitary and epidemiological laboratories, industrial, environmental, chemical-technological, pharmaceutical, research and other institutions. Radiation detectors are CCD arrays with high sensitivity and resolution parameters. Together with the most precise technologies for processing optical elements and new solutions in optical design, this provides a level of spectral resolution sufficient for laboratory measurements, incl. in the pharmaceutical industry. The spectral slit width of 1 nm means that you capture almost any spectrum without distortions associated with the “blurring” of optical density in narrow spectral bands. Measuring some parts of the spectrum using instruments with a larger spectral slit width can lead to distortion of optical density values at selected wavelengths. The high-speed USB-PC interface provides fast bidirectional data exchange with the computer, increasing operator comfort. Main features: optical design - single beam; light sources - halogen and deuterium lamps; detectors - CCD arrays with high sensitivity and resolution parameters; control completely from a personal computer; standard holders for European standard cuvettes (width 12.5 mm, type SF) with optical path lengths from 1 to 10 mm and from 20 to 50 mm; standard USB interface; fixed optical design; automatic measurement of dark currents, measurement of a standard and several samples; support for measuring multiple samples against two or more standards in one session; fast spectrum measurement in a few seconds over the entire range; ease of changing cuvette holders thanks to the large hinged lid of the cuvette compartment; compact dimensions; chemically resistant body material. Operating modes: determination of optical densities, measurement of spectra, calculation of concentration using a programmed method (calibration graph), determination of reaction rates (including kinetics of several samples simultaneously and multi-wave kinetics). Basic package: spectrophotometer; holder for European standard cuvettes (width 12.5 mm, type SF) with optical path length from 1 to 10 mm and from 20 to 50 mm (1 pc.); quartz cuvette type SF with an optical path length of 10 mm (2 pcs.); spare halogen lamp; cable set; software; passport and operating manual with a copy of the verification procedure.
