Model 900 Small Animal Stereotaxic Instrument originally designed by David Kopf Instruments in 1963, is a versatile, easy-to-use instrument that facilitates proper alignment of small animals for the stereotaxic placement of electrodes, micropipettes, cannula and other devices.
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.
The instrument consists of a rugged “U” frame to which is affixed a Model 960 three-dimensional Electrode Manipulator. Model 960 is comprised of 960-E-A AP Slide Assembly, Model 1460-C Swivel and Model 1460-F Manipulator Top Assembly.
Manipulator X,Y, Z adjustment – Metric scale 80 mm travel, 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 13.9″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.
