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.

Labotronics long working distance stereo microscope is a specialized optical instrument designed for observing and working with specimens that require a significant distance between the objective lens and the specimen. These microscopes provide a larger space or "working distance" under the objective lenses, making them suitable for tasks that involve manipulating or repairing samples while maintaining clear and magnified observation. Long working distance stereo microscopes are commonly used in fields like electronics, entomology, and circuit board assembly, allowing users to access and work on delicate or larger specimens without the need for physical contact.
