Slides

Slides are essential tools for sample mounting and microscopic examination in a wide range of workflows, including histology, cytology, cell biology, and pathology. These consumables provide a clean, flat surface to support biological specimens during staining, fixation, and imaging under light or fluorescence microscopes. This category includes both microscope slides and coverslips, which together form the core of any microscopy workflow. Slides may be plain, frosted, or coated (e.g., poly-L-lysine or charged) to promote adhesion of cells and tissues, depending on the application. Researchers use them in immunohistochemistry (IHC), immunofluorescence, live-cell imaging, and bacterial smears. At Wasteless Bio, all slides and coverslips are unused, even if the external packaging has been opened. Listings clearly indicate slide dimensions, coating type, edge finish, and coverslip thickness—ensuring compatibility with staining protocols and high-resolution microscopy systems. By sourcing surplus slides sustainably, labs can reduce procurement costs while maintaining high experimental standards.
