Save $39 now! This is the same as National Optical's model 131 microscope, but with extra-cool and bright LED lighting. This lighting is better than standard tungsten lighting when working with live specimens (like protists) for extended periods of time. The whiter, brighter lighting also provides better contrast with all specimens and works better with a digital camera.This microscope has standard magnification levels of 40x, 100x, and 400x. National Optical model 131-CLED. Lifetime warranty.
