Spectrophotometer
A UV-Vis spectrophotometer measures light absorbance or transmittance across the UV and visible range, a staple tool in research, pharmaceutical, chemistry, and QC labs. Selection depends on wavelength range, spectral bandwidth, wavelength accuracy, photometric accuracy, and accessories.
Subcategories
Single Beam
Single-beam systems generally have a simpler optical path, lower up-front cost, and suit routine measurements; the final choice should weigh light-source stability, reference workflow, required accuracy, and sample type.
Double Beam
The Thermo Scientific Evolution One (1.0 nm spectral bandwidth) and Evolution One Plus (selectable bandwidth) are double-beam spectrophotometers for QC and routine research, running Insight Pro software for fixed, scan, quant, and rate workflows. The GENESYS 10S UV-Vis remains a valuable established/legacy model for the Iran market.
Applications
- Absorbance and transmittance measurement
- Quantitative analysis and spectral scanning
- Kinetics / rate measurements
- QC of raw materials and finished products
