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 instrument consists of a rugged “U” frame to which is affixed a Model 960 three-dimensional Electrode Manipulator. Model 1770 Electrode Holder with corner clamp is included. Assembled to manipulator is Model 940-B Linear Scale Assembly with Digital Display Console.
Manipulator X,Y, Z adjustment – Linear scales have 10 micron resolution and include an easy-to-read compact digital display console. The digital display control features allow “zero” reset at any position. Metric scale 80 mm calibrated 0.1 mm vernier scale.
Angle adjustment – Fully universal joint calibrated on two planes for access from any angle. Vertical alignment pin can be removed for angled settings from 0° – 90° either side of vertical, 2° increments.
Rotation adjustment – Manipulator swivel base can be rotated up to 360°. Manipulator X/Z axis can be repositioned at 90° increments.
The stereotaxic frame is mounted to a 17″L x 10″W base plate and is elevated to bring ear bar height to 53 mm. Ear bar slots on the “U” frame have
0.1 mm verniers for ease in centering the animal. Ear bar zero to posterior end of base plate is 8.763″.
