The BM-20APH trinocular UIS phase contrast microscope adopts UIS infinity optical technology and is highly expandable and can be equipped with auxiliary equipment such as vertical illumination devices and fluorescence devices. It is widely used in research fields such as histology, biology, bacteriology, pathology, medicinal chemistry, etc., as well as teaching work in colleges and universities, and clinical analysis and experiments in the medical community.
This instrument uses an electric light source with continuously adjustable brightness. The chain-type trinocular tube is tilted at 30° and can rotate freely 360 degrees.
