The UVVISion software supports all measurement methods in photometry such as: Fixed Wavelength: Readings at a xed wavelength, with calibration curve Wavelength Program: Readings at numerous wavelengths Wavelength Scan: Wavelength Scan Time Drive: Sequential readings at rapid kinetics Auto Rate Assay: Parallel readings from up to 10 samples at slower assay of activity

Software UVVISion Simple compilation of methods and automation of complex calculations: All parameter of the devices used for the implementation of readings, including the formulas for the calculation of results, are defined as one method and stored in the database. The registered reading data is stored using the corresponding method or a version of the method. Therefore, it is possible at all times to determine with which method the reading data has been generated. If a method is altered, a new version of the method will be produced automatically. The integrated formula editor makes the...

Software Lab Power The Lab Power software supports all basic routine applications in photometry such as: Fixed Wavelength: Measurements at a single wavelength including calibration curves up to 33 standards Wavelength Program: Allows data acquisition at 2–14 wavelengths Wavelength Scan: Provides wavelength scans with real time as well as post-run calculations. Peak and valley determinations, overlay of curves and derivative are possible. Time Drive: Allows sequential measurements of kinetic data at very high speed (up to 2000 data points/min) or over a long period (15 hours). Auto Rate...
