Stereotaxic Alignment System

Model 1900 Stereotaxic Alignment System provides the ability to manipulate and refine the position of the head in 3 dimensional space, prior to exploring inside the head and brain.

The stereotaxic alignment system was originally designed and developed by Joseph Saracione, Cartesian Research Inc. Our patented design offers the maximum stereotaxic adjustment available for positioning the animal’s head; dorsal/ventral, dorsal tilt, coronal tilt, anterior/posterior and midline alignment (nose left/nose right) adjustments. This complete unit is mounted to 18˝x 18˝x 1˝ precision ground aluminum base plate. The overall mass and rigidity of this instrument provides ultimate stability.

Resolution: 1 micron (0,001 mm) all axis

The instrument is fitted with two large dovetail rails for mounting manipulators and additional accessories. The sagittal alignment plate is designed for use with and includes a centering height gauge. This gauge represents the position of the bregma landmark on the top of the skull of the research subject when mounted to the sagittal alignment plate.

Model 1923-B Gas Anesthesia Head Holder and Model 1922 Non-Rupture 60° Tip Ear Bars for mice are included. Custom palate bar design will insure absolute stability of the head. We have incorporated a custom nose clamping device that can be utilized for delivering gas anesthesia via connection to the inlet/outlet port located on the anesthesia mask.

Offering a new level of precision and accuracy, Model 1940 Micro Manipulator provides 1 micron resolution linear glass scales with digital display readout, proving this instrument to be the most advanced manual manipulator available today. Our quick change tool holder allows you to attach any stereotaxic alignment tool and maintain an exact common vertical centerline position tool-to-tool. This valuable feature will assist in reducing surgical time, increase hit rates and greatly reduce potential time consuming errors, which provides a repeatable platform for your research.

Recommended Accessories
Model 1905 Alignment Indicator provides dimensional feedback required for leveling the head.

Model 1910 Dial Test Indicator is necessary for calibrating the stereotaxic manipulator. Indicator will provide dimensional feedback required to verify manipulator alignment is perpendicular and square relative to the precision ground stereotaxic base plate.

Model 1911 Stereotaxic Drilling Unit

Model 1915 Centering Scope 40X magnification is used to assist with positioning the manipulator accurately over the centering height gauge (zero point of reference). This zero point is used to zero out the manipulator readout display and for setting the tool height for all tools to be used in the surgical procedure.
