DS5 Dual Beam UV-Vis Spectrophotometer
The DS5 UV-Vis Spectrophotometer is a high performance dual beam instrument that measures absorption and transmission as a function of wavelength and is suitable for many analytical applications where accuracy and precision measurements are key to your results.
Developed and designed in the UK, the DS5 provides a modern, user-friendly and accurate spectrophotometer for a wide range of sample types and measurements.
Utilising a dual lamp and Czerny-Turner configuration monochromator, the DS5 features a compact, reliable and high throughput optical system which ensures impressive spectral performance. Additional benefits include stray light, baseline flatness, wavelength and photometric accuracy and reproducibility.

UV-Vis Measurement Modes
Photometry Mode: Perform quantitative analyses in either absorbance or transmittance modes. Select from single up to 5 different individual wavelengths, nucleic acid/protein A260/A280 ratios and set up calibration curves for concentration measurements.
Time Scan: Perform kinetic measurements for time periods ranging from 10 seconds to >27 hours. Measurement intervals are factory preset and automatically selected when the scan time is set.
Wavelength scan: Perform a full spectral scan from 190 nm – 1100 nm at any of 9 incremental and preset selectable scan speeds starting from a high resolution 10 nm/min up to a maximum scan speed of 6,000 nm/min. Data is displayed as a graphical spectrum on which data analysis can be performed through the touchscreen interface with zoom, peak-valley, smoothing and other functions available through the easy to use menu interface.
- Concentration measurement
- Absorbance/Transmittance measurement
- Hexavalent Chromium, Nucleic acid measurement (nucleic acid purity, nucleic acid concentration, protein concentration calculation)
- Wavelength scan
- Time change
- Single and multi-wavelength photometry
|Spectrum Overlay||Area Calculation|
To ensure optimum instrument performance, self-diagnosis incorporating a number of parameters and wavelength calibration are automatically initiated upon start-up. Furthermore, the DS5 is equipped with a GLP/GMP feature for analyses requiring validation and auditing. Parameters such as wavelength accuracy, wavelength reproducibility, bandpass, baseline flatness, baseline stability and noise level can all be validated.
