Model 940 Small Animal Stereotaxic Instrument with Digital Display Console combines the quality and accuracy incorporated in all Kopf stereotaxic instruments with state-of-the-art digital linear positioning scales for ease in operation. Our compact design ensures that full range of motion, angulation and rotation of the electrode manipulator is not obstructed by the linear scale assembly connecting cables. 

The process in which the instrument is built and assembled assures that the researcher will be able to make accurate placements. Precise alignment of the slides assures smooth movements resulting in correct use of the atlases.
