UV/Vis Spectrophotometers Catalogue
Benchtop UV/Vis and visible-range spectrophotometers for absorbance, transmittance and concentration measurement. Compare the range by spectral bandwidth, beam configuration and display interface. Exact model specifications and net B2B pricing are confirmed in a formal quotation.
How the range is structured
Spectral bandwidth
Fixed and variable bandwidth models, from routine work to research-grade resolution.
- 4–6 nm — visible-range routine photometry
- 2 nm — general laboratory standard
- 1 nm — methods that specify resolution
- 0.5 / 1 / 2 / 4 / 5 nm selectable — research grade
Beam configuration
Single-beam platforms for routine throughput, double-beam for reference-grade stability.
- Single beam — routine absorbance and concentration
- Double beam — kinetics, long scans, baseline stability
- Xenon source — no warm-up, extended lamp life
Display and interface
Keypad and touch-screen instruments with on-board method setup and reporting.
- Keypad with graphic LCD
- Touch screen for on-board method setup
- USB / RS232 output, direct export to Excel
- Optional PC software with USB dongle
