I have been using a Meiji Techno MT-31 LED Digital Microscope which is compound type 1.3 MP durable microscope. The microscope is built to last and packs a punch with several first-rate features. It is also easy to use, handle and store because of its compact build and ergonomic hand grip. with a powerful magnification that ranges from 40x, 100x, 400x, 1000x you could make the most out of this
microscope including biological use in a laboratory. You can try this out.
