Designed for reliability and value, the Halo VIS-10 combines full scanning capability with excellent resolution applicable to a wide range of routine and advanced procedures in the visible spectrum.
Optimum Optical Performance
The advanced single beam system utilizes a concave diffraction grating monochromator requiring fewer mirrors thus ensuring a shorter optical path and resulting in fewer aberrations and brighter optics (further enhanced with the high energy, long life halogen tungsten lamp). The outcome is greater compactness complemented with increased efficiency and reliability. The silicon photodiode detector commonly utilized in more advanced models also provides superior sensitivity. Furthermore a convex lens focuses the light beam and is especially useful for smaller volume samples. ˙
The spectral bandpass of 5nm ensures optimum performance with excellent spectra and peak resolution. Other specifications include a wavelength accuracy of ±1nm, noise level 0.5% T (500nm, 100%T) and stray light ≤0.5% (360nm NaNO2).
Built-in and Diverse Range of
Photometry Mode. Perform quantitative analyses in either absorbance or transmittance modes. Select from single wavelength and set up calibration curves with up to 8 standards for concentration measurements.
Wavelength scan: Perform a full spectral scan from 330 to 999nm at a selectable scan speed ranging from a high resolving 60nm/minute up to a quick 800nm / minute. Data is displayed as either numerical values or a graphical spectrum in either absorbance or transmittance modes.
