Review on OMAX 40X-2000X Lab LED Binocular Compound 🔬 Microscope: Double Layer Mechanical Stage & Coaxial Coarse/Fine Focusing by Christopher Wiggins

Like a Ph.D. As a microbiologist, I am impressed with the quality of this microscope. It has excellent resolution, almost as good as professional devices. I was hesitant to order at first because one of the reviews complained about the intensity of the LED light source. That's not the case, however, as the microscope has an intensity dial on the bottom of the unit, which the reviewer may not have noticed. The LED provides a very intensive illumination. A microscope is strongly recommended. The lenses are pre-assembled on the microscope, so there are no extra lens storage cases in the box like other brands. There is no blue filter included. Only green filter included. As soon as I let the high dry lens touch the oil after using an oil immersion lens, the high dry lens becomes cloudy. In the lab, the lens is usually cleaned with xylene, but the sales tech advised me to use Walgreen 99% isopropyl alcohol instead. Haven't tried it yet but the seller said they would be happy to replace it if I still have a problem. However, it is preferable that the label states that 99% alcohol can be used to clean the lenses. I must say a few words about the seller. Competent technicians. They are polite and professional. It is a pleasure doing business with them. When I first opened the package, I suspected the unit might need a refurbishment, and with good reason. However, the seller told me they only sell 100% NEW units. All "problematic" devices, if any, will be returned to the manufacturer. Revain, of course, offers excellent service without further ado. It's very easy to order and the return policy is one of the reasons I never thought of using any other e-business system.
