Description
BK5000 Series Biological Microscope is the best-selling laboratory biological microscope in our factory. This microscope adopts an infinity optical system, Plan objective lens, and wide field eyepiece. The configuration of this model is relatively complete, and a phase contrast device and fluorescence device can be added. The observation effect is excellent, equipped with Plan 4X/10X/20X/40X/100X objective lens to meet different magnifications. The BK5000 microscope model has a stable structure, and we have upgraded and improved this microscope many times. Now it has excellent performance and can meet the parameter requirements of most laboratories on the market.
