Analytical Instruments Co., Ltd. Shanghai Jinpeng excellent chemical and biological laboratory equipment and foreign manufacturing experience exclusively produced visible spectrophotometer systematic Xiangjie to quickly check the latest products, quotes, pictures, technical parameters, or product performance comparison, is very convenient to use .
UV / VIS spectrophotometry as a basic laboratory technology, biochemical analysis, life science research and development, especially nucleic acid and protein quantification play an increasingly important role.
SP-723 model is a spectrum visible spectrophotometer SP-72 series one of the products are aimed at research institutes, tertiary institutions developed in the laboratory a high degree of intelligence, good performance, strong function and cost-effective products. Instrument can be connected to a personal computer and equipped with photometric analysis, quantitative analysis and time scanning available on Windows platforms (Windows) to run applications.
Vis Spectrophotometer Model SP-723 Main Features
2'20-byte character type with a backlit liquid crystal display (LCD) displays the current wavelength position, transmittance, absorbance and concentration of test parameters.
Automatic 0% T, 100% T or 0Abs; automatic filter switching, auto-light switch and can be set to switch position, light switch control.
Built-in RS-232C serial interface, can be equipped with printers and personal computer access; purchase spectrum Win-spec applications software, which can control instruments, collection, print, send, save the data.
4 slots standard colorimetric pool frame, which can be placed four 10 mm standard colorimetric pool, continuous testing multiple samples. They can even buy 5-50 mm or 100 mm long optical path than the color pool.
Can test samples of the smallest to 50 increased slightly (requires optional micro-micro colorimetric colorimetric pool and pool frame), to meet the requirements of quantitative analysis of DNA;
