Product Description

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.

Designed and manufactured in the UK, the DS5 provides a modern, user-friendly and accurate UV-Vis 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.

Application Note – “Transmission and Absorbance Measurements of Liquid Samples”

The DS5 can be used for absorbance measurements, an example of the type of research which can be carried out can be found in our application note “Transmission and Absorbance Measurements of Liquid Samples”. You can download the full application note here.

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)

Validation Functions

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.
