PM-755 CUVETTES 50 MM.

PM-756 STAGE MICORMETER Used on the stage of the microscope and provide a simple and reliable means of accurately calibrating eyepiece graticules. A finely divided scale is protected by a cover glass to correspond exactly with the specimen it replaces. The scale is prepared on a glass disc mounted in a metal slide or with scales etched in a glass microscope slide of size (75 x 25mm) The 1mm scale is divided to 100 accurate parts for convenient handling.
