The Model 900R Small Animal Rotational Stereotaxic Instrument is the latest in the 900 Small Animal Series Stereotaxic Instruments. This new series provides a rotating option for the A-P slide assembly, which allows the manipulator to be rotated about the axis of the ear bars. This option will be available on either the right or left side of the Model 900 frame and also available to pivot in an anterior or posterior direction. Now you will be able to rotate the manipulator without moving it off the zero setting and also have at your disposal the ability to be able to rotate the manipulator on its own pivot. Model 960R Rotational Manipulators may be purchased separately for use on existing equipment in the field.
The instrument consists of a rugged “U” frame to which is affixed a Model 960R rotational three-dimensional Electrode Manipulator (includes a Model 1770 Electrode Holder). There is 80mm of vertical, lateral and A-P movement on the manipulator and each is controlled by a screw drive. Each plane has a 0.1mm vernier scale, with a fully universal joint calibrated on two planes for access from any angle.
The frame is mounted to a 10″ x 14″ base plate and is elevated to bring ear bar height to 50mm. Ear bar slots on the “U” frame have 0.1mm verniers for ease in centering an animal. The Model 920 Rat Adaptor, which includes adaptor tooth plate and Model 957 Rat Ear Bars, is included with this frame. Our adaptor has 30mm of vertical travel along a dovetail slide, in addition to 50mm of A-P travel. This unit can be set for any atlas by means of a 0.1mm calibrated vernier scale. Ear bars are 6.3mm square and have 35mm of calibration.
