Biological microscope
Purpose:
The 37XB inverted biological microscope has the characteristic of microscopic observation in culture bottles or incubators. The instrument is equipped with a long working distance flat field achromatic objective lens, a long working or ultra long working distance condenser lens, a large field eyepiece, and a phase contrast device, which can observe transparent living organisms without staining. This instrument is a tool for bacterial culture, tissue culture, microbial detection, and research of liquids, sediment substances, and suspended solids. It can be widely used in departments of biology, immunology, bacteriology, genetics, environmental protection, medicinal chemistry, and other disciplines for detection, teaching, and research.
