PerkinElmer LAMBDA 25/35 Series UV/Vis Spectrophotometer
This PerkinElmer LAMBDA 25/35 Series UV/Vis Spectrophotometer is ideal for use in regulated industries and when a wide range of sampling options and large number of samples are required, these spectrophotometers deliver trustworthy results with a minimum of operator training. True double-beam operation provides the best possible stability and allows references to be measured and corrected in real time. Sealed and quartz-coated high-throughput optics ensure consistent performance throughout the meter’s service life. Very low stray light provides a wide dynamic range. Prealigned deuterium and tungsten halogen lamps allow easy replacement with no service call or downtime. Dual diode detector. Single monochromator.
Model 25 is a fixed-bandwidth system and is ideal for most routine UV/Vis applications and regulatory tests. It features a 1nm SBW configuration and meets all pharmacopeia requirements. Cell changers allow for high volume sampling and cell holders are Peltier controlled. For very high volume sampling, a sipper and autosampler are available.
Model 35 features a variable bandwidth that offers the best solution for QC/QA on liquids, solids, pastes, and powders. This model has all of the features of Model 25, but with the flexibility of user selectable bandwidths, from 0.5 to 4nm in four steps. An integrating sphere allows for measurements on cloth, powders, and other diffuse or light-scattered samples.
UV WinLab* software (included) guides the user through a step-by-step process that simplifies analysis, from sample entry to report generation. For FDA-regulated industries, the optional Enhanced Security* (ES) version of UV WinLab integrates seamless 21 CFR Part 11 technical compliance.
