Duo-Scope Microscope

Even the smallest biologist can explore the microscopic world with this kid friendly Duo-Scope. The unique, dual light source on this microscope allows magnification of both slides and solid objects. Typically, you would need two instruments to view what this one does—a basic biological scope to look at specimens on a slide, and a traditional stereo or dissecting microscope to view solid objects at lower power. This kit also includes over 50 laboratory accessories for hours of scientific research. Cordless battery power allows for field study and its multiple uses provide for limitless exploration. Adult supervision recommended.

Duo-Scope Microscope Review by Douglas Nielsen

This is a great starter for your little scientist. It has a light to look through things and a light to look on top of things. My grand daughter can't stop trying to find things to look at. Hours of fun and learning. (Posted on 4/23/13)
