Model 900/902
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.
Resolution: 100 micron (0,1 mm) all axis
The instrument consists of a rugged “U” frame to which is affixed a Model 960 three-dimensional Electrode Manipulator. Model 1770 Standard Electrode Holder with corner clamp is included. Model 902 consists of two manipulators and two 1770 electrode holders.
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 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″.
- Dorsal/Ventral adjustment dial – Calibrated in 100 micron increments, 1 mm per revolution.
- Dorsal/Ventral adjustment – 30 mm
- Dorsal – 10 mm above ear bar zero
- Ventral – 20 mm below ear bar zero
- Adaptor Plate A/P adjustment – 44 mm
Please indicate if you are working with rat and/or mice during the checkout. We typically include mice accessories as standard but the instruments were designed for versatility. Any standard accessory that is not required can be omitted and the appropriate accessories can be added for your specific research.
