Overview

What this instrument is designed to do, in plain terms.

The FS Series Spectrophotometer covers 8 models, FS300 to FS601S. The comparison table lists the values that differ across the range.

11-inch Touch Screen
Frequently used functions including photometric measurement, quantitative analysis, wavelength scanning and kinetics are displayed on the front interface. Built-in dedicated modules for nucleic acid and protein testing eliminate multi-level menu navigation, boosting efficiency for routine analysis.
Dual-beam system realizes synchronous sample and reference beam detection, compensating in real time for light source fluctuation, temperature drift, baseline drift and ambient interference. It minimizes impacts of lamp energy variation and blank drift during long-term kinetics tests, batch analysis and low-concentration measurement. With 30000 nm/min max scan speed and 0. 02 nm interval, it rapidly acquires full UV-Vis spectra and tracks real-time absorbance and spectral changes.
Equipped with imported deuterium & tungsten lamps, it covers 190–1100 nm UV-Vis range with automatic dual-lamp switching. High-precision optics deliver low stray light, high photometric accuracy and good repeatability.
Narrow slit improves spectral resolution for differentiating similar wavelengths; wide slit increases light throughput to enhance sensitivity for low-concentration samples. Slit adjustment is flexible without extra accessories.
Optional barcode scanner enables fast sample entry and reduces manual errors. It supports permission management, e-signature, audit trail and LIMS connection for standardized lab data management.
Supports cloud, USB-B, email and SMS data output. Optional Wi-Fi, A4 laser and thermal printing.
Extensive accessories are optional, such as auto sample holder, film holder, integrating sphere, peltier/sipper system, etc.
