BDS400 inverted biological microscope is our best-selling microscope. This kind of biological microscope can be used with a variety of objective lenses, phase contrast, dark field fluorescence devices, etc. At present, the microscope can satisfy phase contrast observation and bright field observation at the same time. The maximum magnification of the objective lens is 40 times, and the phase contrast objective lens and bright field objective lens can be sold together according to the demand. The performance of the BDS400 microscope is stable, and it is also a microscope that is constantly updated and upgraded. This microscope is very popular with foreign customers.
