WPI Rat Stereotaxic Instruments

The Classic Rat Stereotaxic Instrument has been a standard in research labs for nearly five decades. The time-proven 'U'-Frame design provides stability and adaptability while the instrument's exclusive, triple-lead screws allow for smooth, consistent movements with rapid positioning.

• Large, easy to read laser engraved vernier scales
• Triple lead screws for fast positioning 80 mm of vertical, lateral and anterior-posterior travel
• Absolute lock at 90 degrees (vertical)
• Brass bushings in manipulator arm permit electrical grounding
• Gas anesthesia compatible
• Easily cleaned durable surface
• Warmer ready base (requires separate controller and temperature probe) used to maintain body temperature throughout surgical procedures

Versatility of Positioning

The universal joint allows the investigator to angle the probe in either the anterior-posterior or the lateral-medial planes. The improved locking mechanism on the WPI Rat Stereotaxic Instruments will hold any angled position without slippage. Of course, it also provides an absolute lock at the vertical position. The manipulator arm may be swivelled out of the way for convenience in installing the animal or performing a procedure, then returned to the same point reliably with the aid of the locking face block above the swivel joint.

Additional Functionality For Digital Stereotaxic Models

• Saves time and improves accuracy
• Easy-to-read digital display and sealed electronic sensors operation of the instrument is easy and precise
• Simply move your probe to an established reference point (e.g. Bregma), zero the LED display and move to the desired coordinates

A zeroing function allows the user to set a reference point for targeting specific coordinates on the animal’s skull for injection, implantation, etc. Calculation of distance measurements via the vernier scales is thus no longer necessary…saving the user valuable time and improving accuracy. It's as easy as 1-2-3.

1. Find reference point, e.g. Bregma
2. Reset zero on touch screen display
3. Move to the desired coordinates

Target coordinates can be programmed into the memory of the digital stereotaxic instruments.
