Product news

PerkinElmer Life and Analytical Sciences, a global leader in application-focused measurement and analysis solutions, today announced at PITTCON® 2008, Booth #2555, the global introduction of the LAMBDA™ XLS, a UV/Vis spectrophotometer for Quality Assurance/Quality Control (QA/QC) and teaching laboratories, and the LAMBDA™ Bio, a UV/Vis spectrophotometer designed specifically for biological science laboratories.

Both the LAMBDA XLS and LAMBDA Bio are designed as low-cost, routine platforms with a number of pre-configured standard methods and the capability to add customized methods, addressing a wide range of applications.

The LAMBDA XLS, on display at the PerkinElmer booth, was designed with a focus on productivity and ease of use. The LAMBDA XLS and Bio models include a large, clear on-board display and robust spill-resistant keypad. With its intuitive graphical interface and wide range of local language options, users in manufacturing QA/QC, environmental, teaching and food analysis laboratories are able to perform wavelength, scanning, concentration studies and biological assays with ease.

“The LAMBDA XLS was developed in response to customer needs in today’s fast-paced, multitasking laboratory environment for instrumentation that generates results quickly and delivers a high level of stability and robustness,” said Martin Long, Vice President, Materials Characterization, PerkinElmer Life and Analytical Sciences. “It includes methods for many of the analytical challenges facing the global ecosystem.”

The LAMBDA Bio is pre-configured with standard methods for ease of access, including DNA, RNA and Oligonucleotides concentration and purity, protein assays and cell density measurements.

Both the LAMBDA XLS and LAMBDA Bio have no moving parts and feature an ultra-long lifetime Xenon lamp helping to ensure robustness, maximum uptime and low cost of ownership. The high quality split-beam optical design provides high stability and run-to-run reproducibility for added assurance of results.

The instrumentation is available for purchase online through the PerkinElmer Web site.

UV-Visible SpectroscopyUltraviolet-visible (UV-Vis) spectrophotometers are used to measure the interaction of UV and visible light with a sample, including transmission, reflectance & absorbance. The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics. Find the best UV-Vis spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.OligonucleotidesOligonucleotides are small nucleic acid polymers, usually less than 20 bases in length. Oligonucleotides can be made via enzymatic cleavage or more commonly by chemical synthesis with polymerases. Their use includes FISH, southern blots, microarrays and as primers in PCR. High fidelity synthesis kits and detection systems are available for easy production and detection, respectively.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.
