Reliable, upgradeable and flexible spectrophotometer. Excellent and reproducible results.
Application Area:UV-vis studies in coordination chemistry
"An upgradeable, flexible UV/Vis system, you can modify each parameter affecting the light beam from the lamp to the detector, even it is possible to use your own source of light. So, it is very useful if you can carry out measurements with non-routine parameters. The performance and reproducibility of the measurements between 200 nm and 900 nm is very good. You can use different modules in order to measure the UV-vis spectra of solution, or the diffuse reflectance spectra of powders... I used this equipment largely to calculate the band gap of semiconductor nanoparticles with very reliable and reproducible results. The only drawback may be the higher cost of the equipment compared to other more routine equipment. "

"We’ve had our Lamda650S for three months and so far so good. We've found it very easy to use. We primarily use it for film analysis to support product development. We have eliminated a two step process into one. We were measuring color and reflectance on two separate units. This has reduced sample handling and only requires one scan to obtain all the information needed. P-E provided a technical expert for our onsite seminar and training that was invaluable for the primary users and technicians."
This system is for high performance measurements between 190 nm and 900 nm. Applications include color analysis of paints and textiles, turbid solutions, and enzyme kinetics in life science, biochemistry, and pharmaceutical laboratories. The LAMBDA 650 can be upgraded for higher sampling. A 150 mm integrating sphere is included for ASTM, CIE, and DIN measurements.
All of our LAMBDA UV/Vis/NIR & UV/Vis Spectrophotometers offer features and accessories designed for maximum versatility delivering optimal performance and value:
• Universal Reflectance Accessory (URA) - Snap-on module, changes angle automatically – A PerkinElmer exclusive!
• Unmatched sample compartment size
• Dual Sampling Compartments offer more options
• Integrating spheres to 150mm
• General Purpose Optical Bench (GPOB) handles a wide range of samples – including lenses and telescopes
• Wide range of sampling modules requiring only seconds to change
