Dual Beam UV-Vis Spectrophotometer The DS5 UV-Vis Spectrophotometer is a high performance dual beam instrument suitable for many analytical applications where accuracy and precision measurements are key to your results. Developed and designed in the UK, the DS5 measures absorption and transmission as a function of wavelength and provides a modern, userfriendly 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. > User selectable variable bandpass options at 0.5, 1.0, 1.5, 2.0 or 4.0 nm > Fast scanning – up to 6,000 nm/min to aid sample analysis throughput > Automatic accessory recognition connected to the DS5 > Modern touchscreen interface with intuitive menus and functions to ensure ease of use for standalone control > USB, SD card and internal data storage for convenient retrieval of methods and results > Compact footprint to maximise available bench space in the laboratory

SAMPLE ACCESSORIES STANDARD CELL HOLDER LONG PATH CELL HOLDER GLASS FILTER HOLDER FILM HOLDER The standard cell holder is 2-position and holds traditional 10 mm path length cells. A micro-volume cell holder option for 50 μl cells is also available. Designed for low concentrations or absorbance, the long path cell holder holds two rectangular cells with an optical path length of 10 mm to 100 mm. Designed for measuring the transmittance/absorbance of glass samples or filters. Sample dimensions up to 55 mm x 100 mm with 5 mm thickness can be accepted. Designed for measuring the transmittance/absorbance...

USER INTERFACE FUNCTIONS HOME SCREEN MEASUREMENT SETUP SPECTRUM OVERLAY AREA CALCULATION 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.
