We provide an inverted biological microscope, a specialized optical instrument designed for studying biological specimens that cannot be easily examined on a conventional upright microscope. Inverted microscopes have their light source and objective lenses positioned below the specimen, allowing for the examination of cells, tissues, and other biological samples cultured in containers like Petri dishes or multi-well plates. These microscopes are commonly used in cell biology, microbiology, and tissue culture applications, providing a clear view of live cells and tissues in their natural environment.
