VSP-723S visible spectrophotometer can meet the needs of qualitative and quantitative analysis in the fields of materials research, drug analysis, biochemical and clinical inspection, water quality analysis and control, food safety inspection and so on.
Features
Wavelength accuracy: the instrument built-in spectrum characteristic wavelength automatic wavelength detection and correction, to ensure the accuracy of the wavelength and long-term stability.
Wavelength range: the instrument wavelength range covers 320nm to 1100nm, to achieve the same level of equipment, the widest wavelength range, to meet the vast majority of spectrophotometric analysis of the wavelength of the test requirements.
High-speed scanning: scanning speed and multi optional by high precision wavelength drives mechanism, with high precision stepping motor subdivision technology and high-speed digital signal processing technology, the highest wavelength scanning speed to achieve world-class level 7000nm/min and wavelength shift speed higher than 10000nm/min. High speed scanning can help users to capture the spectral changes in the sample moment, improve the efficiency of work.
Photometric accuracy: the overall aluminum alloy die casting die, ensure the optical path to meet the design requirements, improve the efficiency of process assembly, to achieve a high precision test index.
Single U disk storage: equipped with U disk storage function, the single test of the quantitative data stored in the U disk, file format compatible with Excel and other applications to facilitate user management data.
Single quantitative analysis feature rich: electronic systems with 32-bit ARM core processor system, equipped with 128 * 64 LCD screen to display, single quantitative analysis function can be tested for multi wavelength, standard curve fitting and measurement, standard coefficient equation input, the standard equation read and storage, data storage and print, the quantitative concentration test function.
Light source replacement convenient: the instrument deuterium lamp using universal flange fixed, only two screws can complete the operation of deuterium lamp replacement work, no need to adjust the light path, so that the maintenance of the instrument is more simple and reliable.
USB communication mode: the instrument uses the USB way to connect the computer, the high penetration rate, the communication speed, the automation degree is high. Compared to the traditional RS232 serial port, users can achieve online communication without any parameter setting.
Powerful software: the software can realize the spectral scan, scan time, dynamic test, quantitative analysis, multi wavelength analysis and formula calculation, processing map, peak search, print data, DNA / RNA testing, instrument calibration, performance verification functions, meet the various demands of different sectors of the analysis.
