The Richter Optica HS-MSG microscope mechanical stage is made for use with the MDS2 middle school microscope and the HS-1 high school microscope. This mechanical stage replaces the stage clips on the Richter Optica MDS2 or HS-1 microscope. The mechanical stage holds the slide in place and allows it to be maneuvered left-to-right or front-to-back by moving one of the two adjustment knobs. The microscope mechanical stage provides greater control over the specimen when looking through the microscope.
