Dual COOL LED Illumination and The best "TOY"microscope for scientists of all ages! Learning can be Fun! The greatest measure of an educational product’s success, is when the learning can be cleverly disguised as fun and games. That is exactly what this microscope has been able to achieve, time and time again. The My First Lab Duo-Scope assures you of many hours spent exploring an infinite number of both living and non-living specimens, far away from the TV and game consoles,as we as get you on the road to a wonderful world of science, education, adventure, and discovery. WHY the Duo-Scope is the best… This microscope, unlike others, offers each user the unique ability to readily switch between two basic modes of observation, allowing the scientist to view both microscopic specimens on slides, as well as lager solid objects, such as leaves, small rocks and bugs, quickly and easily. In the past, one would have required two separate instruments to achieve this; however with the Duo Scope, we have combined the features of a biological microscope and a stereo microscope into a single unit and have made it possible for the user to choose their desired mode, simply by flipping a switch.
