UVmini-1240 UV-Vis Spectrophotometer

Factor method for input of simple constants
One point calibration curve with one standard sample and a point through the origin
Multi-point calibration curve of the application requiring various standards. 1st, 2nd, and 3rd order polynomial fitting for calibration come standard.

Two or Three wavelength quantitative analysis for measuring turbid samples or for measuring the effects of another distinguishable component.

The large liquid-crystal display (LCD) has been incorporated with easy-to-follow prompts, large fonts, and graphics to help reduce the time needed to get your results. The description on the instruments soft keypad quickly guides you through specific programs.

The UV Mini comes standard with a Spectrum mode that allows for full spectral data acquisition over the wavelength range of 190nm to 1100nm. Upon completion of the spectral scan, the peaks and valleys can be marked within a few seconds. The standard peak pick function allows for clear and accurate detection of the most sensitive wavelengths.

Methods, results, and raw data can be saved on either the standalone instrument, optional dedicated IC Data cards, or within a directory of an IBM Compatible PC with the help of the optional New UV Data Manager software. This provides unlimited storage and expanded capabilities in archiving methods and management of essential results.

The UV Mini provides flexible print options with the use of either a thermal screen copy printer or a variety of different PC printers. The screen copy printer enables instant printing of tabulated data as well as copied information directly from the screen. The PC printers can be utilized for the same functions and for finer print resolution of spectral data.
