Inverted Biological Microscope, LWD200-37T

The instrument is equipped with a wide working distance concentrating mirror, flat field achromatic objective lens and phase contrast device, so it can use a variety of culture dishes and culture bottles, especially suitable for observing and recording attached to the bottom of the culture dish or suspended in the medium. Living material cells and tissues, fluids, sedimentation, etc., while observing other transparent or translucent objects as well as objects such as powders and fine particles. The instrument can also play a significant role in the field of food inspection, identification of water quality, crystal structure analysis, and chemical reaction sediment analysis, for scientific research, universities, health care, disease prevention, animal husbandry, and other departments.
