Spectroscopy instruments are essential analytical tools used to measure the interaction between electromagnetic radiation and matter. In laboratory settings, spectroscopy is vital for investigating molecular structure, chemical composition, binding interactions, and biomolecular quantification. These instruments are widely used across pharmaceutical R&D, biochemical research, clinical diagnostics, environmental testing, and material science. Spectroscopy encompasses several techniques, each serving a specific purpose. The most common systems include UV-Vis spectrophotometers, fluorescence spectrophotometers, and infrared (IR) spectrometers. These instruments are frequently used in workflows involving nucleic acid quantification, protein assays, enzyme kinetics, drug interaction studies, and quality control testing. UV-Vis spectrophotometers measure absorbance across the ultraviolet and visible spectrum. They are commonly used to determine the concentration of DNA, RNA, and proteins by detecting absorbance at specific wavelengths (e.g., 260 nm, 280 nm). These systems are staples in molecular biology labs, where they support applications such as nucleic acid purity assessment, enzyme kinetics, and reagent standardization. Fluorescence spectrophotometers detect fluorophore-labeled molecules with high sensitivity, enabling detection of proteins, small molecules, and nucleic acids at very low concentrations. They are widely used in drug discovery, cellular assays, and biomarker detection, as well as for reporter assays like GFP and FITC labeling in molecular and cellular biology. IR spectrometers measure infrared absorption, which correlates with chemical bonds and molecular vibrations. This technique is commonly used for functional group identification, polymer analysis, pharmaceutical quality control, and metabolite fingerprinting. Wasteless Bio offers access to affordable, high-quality surplus spectroscopy instruments with full technical specifications, including wavelength range, detection limits, sample capacity, and software integration. Buying second-hand helps labs reduce costs while contributing to a circular economy by extending the lifecycle of precision instruments essential to research and diagnostics.
