The 20-Piece Compound Microscope Kit from Vivitar comes with a range of specimen collection and preparation tools, prepared slides, interchangeable eyepieces and more. This monocular microscope has three objectives, providing 150x, 450x, and 900x magnification adequate for viewing a variety of specimen types. This beginner microscope features several user-friendly functions that enable convenient viewing. Instead of sliding the specimen around by hand, this microscope's mechanical stage permits enhanced specimen control on both X and Y axes. A generously sized rotary focus knob, under stage illuminator, and lightweight frame make this entry-level microscope ready for observations in the field or the classroom.
