Brightfield&Darkfield Biological Microscope BM300D series:Description:Composed the professional darkfield kits with the advanced biological microscope BM300, it becomes the darkfield microscope.it is easy to change bright field obervation into the darfield observation. It is a simple procedure which can be used on live transparent specimens, specimens which normally need to be stained (and therefore killed).you can use the dark field in the research of live bacterium, as well as mounted cells and tissues. It is more useful in examining external details, such as outlines, edges, grain boundaries and surface defects than internal structure.Features: 1. Infinite corrected optical system2. Super light LED lamp illumination, long life and lower consumption3. Comfortable operation with updated and ergonomic design4. Professional darkfield condenser, and darkfield 100x lens with cone diaphgragm.5. more useful in examining external details, such as outlines, edges, grain boundaries and surface defects6.
