A FAbulouS way of performing UV-Vis Spectroscopy!

  • Compact Design;
  • Fast Scanning;
  • Flexible;
  • Great Performance;
  • Powerful;

FAbS is our first ready-to-use and fully automated spectrophotometer for UV-Vis-NIR. It combines high-performance and modular light sources with our outstanding CCD-array detector-based spectrometers in a compact design, with a similar size to an A4 paper.

Created to be an essential instrument in analytical, clinical, and research laboratories, FAbS meets the excellence of spectroscopy and fulfill the requirements of most demanding research, educational, or quality control applications. With the FAbS spectrophotometer, users can measure accurate full spectrum scans in three wavelength ranges (UV-Vis, Vis-NIR, and UV-Vis-NIR), in just a few seconds!

Great Things Come In Small Packages!

With a footprint comparable to an A4 sheet, FAbS Spectrophotometer is the ideal solution to fit in modern and busy labs where every centimeter matters.

Fast Scanning Equals High Productivity!

Tired of waiting minutes for results? Full spectra are acquired at fast scanning speed, starting at milliseconds. You can control the acquisition speed and despite your selection, one thing is for sure: it won’t take more than a few seconds!

Absorbance and Reflectance Directly In or From the Sample Container!

Sarspec has multiple accessories to maximize the flexibility of your FAbS Spectrophotometer. Connect a reflectance probe and measure the reflectance of solid and powder samples. Use a transmittance probe or a flow cell to measure the absorbance and transmittance of liquids directly in the sample container.

Compliant with EU and US Pharmacopeias!

The design of the FAbS Spectrophotometer leads to an elevated performance in terms of optical resolution, linearity, stray light, and accuracy.

Your Best Partner in UV-Vis Spectroscopy!

The new LightScan 2.0 software perfectly controls your FAbS Spectrophotometer and connect it to all the accessories. It enables different working modules, such as Absorbance, Transmittance, Reflectance, Quantification, and Kinetics and the module Color to determine and compare the color coordinates of your samples.
