Small Animal Stereotaxic Instrument
SASI
The small animal stereotactic instrument SASI, originally designed by Thomas RECORDING in 1998, presents an exiting stereotactic manipulator for precise stereotactic procedures on small animals. The SASI 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.

| Data | |
| Number of degrees of freedom: | 6 |
| XYZ-Manipulator X,Y,Z adjustment: | Metric scale, x=-10…+10 mm, y=-10…+10mm, z=0…30mm travel, calibrated 0.05 mm vernier scale. |
| Angle adjustment: | Xyz manipulator is moving on a round arch. Continuous angel adjustment of xyz manipulator position: angle settings from -40°…+ 40°. |
| Rotation adjustment: | Microdrive od electrode holder coupled to the xyz manipulator can be rotated up to 360°. |
The stereotaxic frame is mounted to a base plate and is elevated to bring ear bars up to the required heigth.
Rat and mouse adaptor features offer various stereotaxic adjustments.
Features
The major kinematic difference of the SASI in contrast to other stereotaxic instruments presently available on the market is, that in the SASI system all translational joints kinematically follow the rotational joints. This is realized by a curved guide (round arch) first introduced in animal stereotaxic instruments by Thomas RECORDING.
