Lambda 25, 35 and 45 Systems Introduction LAMBDA 25/35/45 UV/Vis systems are ideal for routine analysis in the busy industrial or academic laboratory. The systems are easy to operate and deliver trustworthy results with the minimum of operator training. With over 15,000 units installed worldwide, PerkinElmer’s superior technology and build quality has proven itself under the toughest conditions. PerkinElmer’s extensive suite of Instrument Performance Verification (IPV) tests confirms high quality performance over the lifetime of the system, and for regulated industries the Enhanced Security (ES) version of UV WinLab integrates seamless 21CFR part 11 technical compliance. LAMBDA 25 LAMBDA 35 LAMBDA 45 Choose the LAMBDA 25 for routine UV/Vis applications including liquids analysis, pharmacopeia and regulatory tests. Choose the LAMBDA 35 for measurements on liquids, solids, pastes and powder samples and regulatory tests requiring variable bandwidths. Choose the LAMBDA 45 for demanding low stray light measurements Range: 190 nm - 1100 nm Range: 190 nm - 1100 nm Range: 190 nm - 1100 nm Bandwidth: 1 nm (fixed) Bandwidth: 0.5 nm - 4 nm (variable) Bandwidth: 0.5 nm - 4 nm (variable) Integrating sphere option Pre-monochromator for reduced stray light Technical Specifications The specifications listed below are guaranteed specifications and are based on final test pass criteria used in production.
