       OUR NEW SOFTWARE UV-WIN 6.0 WITH 3D SPECTRA
 
 Now all  Labomed, Inc. split and double beam spectrophotometers with our newly developed  software called UV-Win 6.0 can be used with Windows XP, Windows 7 and Windows  8. It is capable of testing more applications with its RS-232 and USB  connections, and supports the data export of measured results to the PC and  then, if required, a USB flash drive, when additional data storage is required. One of the new  features is that it provides 3-D graphing of the spectral results.
 
        Such operations as photometry measurement,
            spectrum measurement, quantitation measurement and kinetic measurement
            are offered in UV-Win Windows applications.

            to the user-entered formula.
Up to
            10 spectra and time-course curves can be measured and recalled in
            memory with data-handling of arithmetic calculation, logarithmic
            calculation, reciprocal calculation, smooth, derivate (1st ~ 4th),
            Abs to/from %T conversion and peak pick.
Up to
            24 standards can be entered and measured for the fit of calibration
            curve with order to 1st ~ 4th. Offered are the quantitation methods
            of single wavelength, two-wavelength, coefficient two-wavelength,
            three wavelength and 1st ~ 4th derivatives.
Kinetic
            measurement can monitor the changes of absorbance and transmittance
            against time course at 10 different wavelengths. This module allows
            flexibility in manipulation and data display.
With
            the Windows clipboard, the measured data and graphics can be copied
            to other applications software for reports. Also offered are filing
            functions, display functions, and others (such as auto file and repeat
            measure/scan etc.).
