About This Product

State-of-the-art stopped-flow system. The stopped-flow method is a method in which a sample solution is mixed at high speed, the flow is stopped instantaneously, and subsequent changes in the absorption spectrum, fluorescence, etc. of the sample solution in the visible, ultraviolet, and near-infrared regions are rapidly measured. It is possible to measure the reaction rate of various high-speed reactions on the order of milliseconds to seconds, such as homogeneous catalytic reactions, enzymatic reactions, redox reactions, structure formation, and particle generation, and to detect short-lived intermediates. It is possible to evaluate activity, derive reaction activation energy, analyze reaction mechanism, evaluate reaction inhibitors and promoters, and compare properties of related substances and new materials. Our stopped-flow equipment has a proven track record of more than 35 years, and is increasingly used in cutting-edge basic and development fields such as energy and environment-related, medical and biotechnology, and nanoscience.

■Features

・Simultaneous rapid scan photometry wavelength width of 560nm or more using newly designed polychromator ・Continuous measurement of up to 8,000 absorption spectra at up to 1ms intervals ・Supports fluorescence measurement and faster measurement with Photomul time-varying photometry mode

■Applications

・Characteristic evaluation of new metal complexes and organic synthetic substances such as porphyrins and fullerenes ・Analysis of reaction mechanisms of active oxygen, free radicals, and antioxidants ・Measurement of drug properties ・Analysis of nanoparticle synthesis process ・Analysis and characterization of the reaction mechanism of artificial heme proteins ・Analysis of protein-ligand interaction ・Analysis of protein folding reaction process ・Activity evaluation of membrane proteins such as aquaporins

■Options

・Circulating constant temperature water tank ・Fluorescence measurement kit ・Scatter measurement kit ・Mixing ratio variable kit ・Trace 10mm cell (mixed dead time approx. 1ms) ・Ultraviolet light source (30W D2 lamp) ・Light source for fluorescence measurement (150W Xe-Hg lamp) ・Double mixing device with automatic cock ・Global analysis software

■Configuration
