Fluorescence Microscopes

Fluorescence microscopes are advanced imaging tools designed to visualize and analyze fluorescently labeled biological structures within cells, tissues, and whole organisms. These instruments use high-intensity light sources—such as mercury or LED lamps, lasers, or xenon bulbs—to excite fluorophores that emit light at specific wavelengths. This emitted light is then filtered and detected to generate high-contrast images of structures not visible with conventional light microscopy. Fluorescence microscopes are essential in molecular biology, immunology, pathology, neuroscience, and cell biology. By tagging proteins, nucleic acids, or organelles with fluorescent dyes or genetically encoded fluorophores like GFP, mCherry, or FITC, scientists can study protein localization, gene expression, cellular dynamics, and signal transduction pathways in real time. Fluorescence imaging is commonly used for immunofluorescence staining, live-cell tracking, co-localization studies, and intracellular trafficking analysis. There are several fluorescence microscopy techniques available, including widefield fluorescence, epifluorescence, and more advanced methods like confocal, super-resolution, and multiphoton microscopy. Each technique offers different advantages in terms of resolution, depth penetration, and signal-to-noise ratio. Modern fluorescence microscopes often include features such as automated filter wheels, motorized stages, digital cameras, and image analysis software. Some systems are integrated with environmental chambers for temperature and CO₂ control, supporting long-term live-cell imaging. At Wasteless Bio, we offer access to gently used and surplus fluorescence microscopes from leading manufacturers. Listings include detailed information such as magnification range, filter cube configuration, excitation/emission spectrum compatibility, and camera resolution.
