Classroom Microscopes by Meiji Techno

The TM400 Series of compound microscopes are ideal for classroom applications that demand the quality and durability guaranteed by Meiji's limited lifetime warranty. All TM400 Series microscopes have a built-in adjustable slip clutch to prevent damage to specimens or objectives, and a tension adjustment collar on the focusing controls. Although these scopes are bulit to stand up to years of student punishment, rest easy that inexpensive replacement parts are available as compared with other "cheaper" microscope brands "throw away" models.
