Classic Laboratory Upright Fluorescent Biological Microscope


BS-7000A fluorescence microscope is a laboratory fluorescent microscope with perfect infinite optical system. The microscope uses mercury lamp as the light source, the fluorescent attachment has 6 positions for filter blocks, which allows easy change of filter blocks for various fluorochrome.


  1. Perfect image with infinite optical system.
  2. High resolution fluorescent objectives are optional for excellent fluorescent images.
  3. Advanced and precision lamp housing reduces the light leak.
  4. Reliable power supply with digital display and timer.


BS-7000A Fluorescence microscope is used to study the absorbing, transportation, chemicals distribution and positioning in cells. It is widely used in universities, hospitals and life science labs for disease examination, immune diagnosis and scientific research.
