Student Biological Microscope (No Box) Long Focus Type SGT-400RLBL 114-087 1 Set

A 400x biological microscope with switchable light source that allows the reflector and LED light source to be replaced. This is useful if you want to teach students how to use a microscope using a reflector, but want to use an LED light source for actual observations. The reflector/LED light source base is a plug-in type, so it can be easily removed and attached. It is equipped with a fine adjustment handle that allows for precise focusing. The 40x objective lens has a long distance from the specimen before it can focus, making the tip of the lens less susceptible to dirt.
