Delta Optical IB-100 LED Inverted microscope (DO-3719)

This microscope is designed for bright field and phase contrast observations, with the option to upgrade to 400x phase contrast and an epifluorescence set (filters B, G, U, and V).

Applications
Suitable for universities, laboratories, research centers, environmental protection, medicine, biology, tissue and cell culture analysis (e.g., in microplates or polystyrene bottles), sediment analysis, observation of plant and animal microorganisms, cytology, microbiology, parasitology, plankton research, and more.
