INO3690BI Inverted Biological Microscope


INO3690BI Inverted Biological Microscope

The inverted biological microscope is a branch of the biological microscope, which is used for observation and research of biological slices, biological cells, bacteria, living tissue culture, fluid sedimentation, etc., and can observe other transparent or translucent objects, powders, fine particles, and other objects. Compared with ordinary biological microscopes: it is suitable for observing and recording living substances attached to the bottom of Petri dishes or suspended in the culture medium and can also play a huge role in the fields of food inspection, water quality identification, crystal structure analysis, and chemical reaction sediment analysis.



  1. Ergonomic Viewing Head    

    360 ° rotatable viewing head with 50mm-75mm adjustable inter-pupillary distance, the eye-point can be raised 34mm directly by rotating the tube at 65mm IPD, more convenient and faster than the traditional way.   

  2. Safe and Efficient LED    

    Illumination Adopting CREE 5W LED, energy saving and long-lasting, no fever, the illumination is safe and stable.  

  3. Intelligent ECO System    

    Based on the concept of energy conservation and environmental protection, INO3690BI is designed with an ECO system. The illumination power can be automatically on or off through infrared induction.    

  4. Practical Marking Objective    

    New designed "objective" with ink inside for marking the target, is very practical and effective to extract the target cell when observing and culture the living cell.   

  5. A Kit for Smartphone Connection    

    The specially designed kit which can be inserted into the eyepiece tube for combining a smartphone with a microscope, keep a record of time by taking photo or video.
