LAMBDA 25: PerkinElmer UV/Visible Spectrophotometer
The PerkinElmer LAMBDA 25 is a UV/Visible spectrophotometer designed to meet the needs of laboratories performing routine analyses and regulatory testing. With its double-beam optical system, it offers exceptional stability and precise measurements, ensuring reproducible results over the long term. It covers a broad spectral range from 190 to 1100 nm, making it suitable for numerous applications, including liquid solution analysis, pharmacopeial testing, and quality control.
Its optical system relies on sealed and quartz mirrors, allowing optimal light transmission and minimizing interference. With a fixed bandwidth of 1 nm, the LAMBDA 25 is ideal for standard analyses requiring precise resolution.
The instrument is equipped with pre-aligned deuterium and tungsten lamps, providing complete coverage of the UV/Vis spectrum and automatic transition between light sources for uninterrupted analyses. These lamps are easily replaceable without requiring technical intervention, thus minimizing laboratory downtime.
One of the major strengths of the LAMBDA 25 is its UV WinLab software, which guides the user through the various stages of analysis, from data acquisition to report generation. This intuitive interface helps eliminate handling errors while offering full compliance with regulatory requirements, including GLP, ISO, and pharmaceutical standards. A version of the software integrating 21 CFR Part 11 requirements is available for laboratories subject to FDA regulations.
In terms of performance, the LAMBDA 25 boasts a wavelength accuracy of ±0.1 nm and reproducibility of ±0.05 nm. Its photometric stability is remarkable, with a drift of less than 0.00015 A/h at 500 nm, ensuring increased reliability of results. Photometric noise is minimal, ensuring excellent signal quality even for samples with low absorbance levels.
Regarding robustness, its CNC aluminum chassis provides high resistance to vibrations and thermal variations, ensuring a prolonged lifespan with minimal maintenance. Ergonomics have also been considered to optimize laboratory work: its compact design saves space while facilitating access to sampling compartments.
The LAMBDA 25 is compatible with a wide range of accessories to adapt the device to different applications. It can be equipped with glass or quartz cells, an S10 automatic sampler, a Peltier temperature control module, or a fiber optic probe for in situ measurements. These options expand the analytical capabilities of the instrument according to the specific needs of laboratories.
The PerkinElmer LAMBDA 25 stands out for its reliability, ease of use, and precision, making it an ideal choice for laboratories seeking a high-performance spectrophotometer that meets quality control and regulatory requirements.
