Dual Beam UV-Vis Spectrophotometer The DS5 UV-Vis Spectrophotometer is a high performance dual beam instrument suitable for many analytical applications where accurate measurements are key to your results. Key Features Dual beam Optical configuration for quick, accurate results Variable bandpass Developed and designed in the UK, the DS5 measures absorption and transmission as a function of wavelength and 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. It can be configured with PC control software or as a standalone instrument using the touchscreen included in every DS5 unit. Fast scanning Up to 6,000 nm/min to aid sample throughput Touchscreen interface With intuitive menus and functions for standalone control Visacle® software Optional package for PC control, standard or 21 CFR compliant

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 Choose between touchscreen or software operation The standard DS5 is operated via a touchscreen included with every instrument. Visacle® PC-controlled software is offered for laboratories wishing to control their instrument from a computer or manage their experiment database. FDA 21 CFR Part 11 compliance is also available.
