VARIAN SpectrAA 220FS is a double-beam spectrophotometer designed for color-imaging, analytical and characterization applications. This instrument is ideal for measuring transmittance, absorbance and reflectance over a wide range of wavelengths from the UV to the near infrared. The unit features a robust double-beam optical system which provides superior stability and high resolution spectral scans. SpectrAA 220FS utilizes a tungsten-iodide lamp, a holographic grating and a CCD linear array detector to detect light. The lamp is used to produce a continuous spectrum of light which is then filtered by the holographic grating to isolate the desired wavelength. The detector then measures the intensity of the light at that wavelength. The instrument also features an autostepper, which can be used to continuously scan the range of wavelengths to build a complete spectrum. The number of wavelength scans per minute is user-defined, and the unit can produce a scan resolution of up to 0.1 nm. VARIAN SpectrAA 220FS features an intuitive touchscreen user interface, along with user friendly menus for setting up scans and monitoring their progress. The unit also comes with a data processor that can be used to store data and process it for analysis. The spectrophotometer has a detection range that covers the majority of the spectrum from 200 nm to 1000 nm range, making this instrument suitable for applications that require measurements in the visible, ultraviolet and infrared regions. SpectrAA 220FS includes an attenuator for the transmittance mode, enabling the user to accurately measure samples of varying concentrations. The instrument also comes with a sample holder that enables the user to take measurements of solid, liquid, powder and viscous samples in the reflectance mode. Overall, VARIAN SpectrAA 220FS is an easy-to-use, precise spectrophotometer that is perfect for applications in colorimetry, analytical and characterization. Its dual beams and wide range of wavelengths provide exceptional stability and resolution, while its data processor and automated functions make it highly user-friendly.
