Benefits

• Versatile positioning
• Easy to read scales
• Convenient for electrophysiology because the frame may be grounded
• Ability to expand to accommodate a variety of large animals

Applications

• Stereotaxic surgery for large laboratory animals
• Electrophysiology applications

WPI’s Parallel Rail Stereotaxic Frame systems are heavy-duty research instruments for large laboratory animals such as cats, monkeys and dogs. The solid, large frame and superior rigidity ensure the precise alignment of animals for stereotaxic surgery, injection and recording. The system can accommodate up to four manipulators with 100 µm resolution on each axis. Each manipulator can smoothly move to and lock at any location on both parallel rails in a range of 20 cm.

WPI’s Precision Stereotaxic Instrument is built around the time-proven U-frame design concept, providing stability, and adaptability to most species. Precision alignment ensures accurate placement of electrodes, micropipettes, and other devices. It is ideal for researchers in need of a versatile, reliable instrument for stereotaxic procedures with small animals

Versatility of positioning

The manipulator arm controls medio-lateral and vertical positioning via lead screws with 80mm of travel. This allows the fastest positioning possible, consistent with lining up the scales easily at a given coordinate. The antero-posterior movement is controlled via a dovetail slide movement, with 80 mm of travel possible in each direction. A universal joint allows the investigator to change the angle of the probe up to 90° in either the antero-posterior or medio-lateral planes. The locking mechanism will hold any angle position without drift or creep. It also provides an absolute lock at 90° vertical.

Easily read scales

All scales are oriented to be read easily from the open end of the “U”. This is the position from which most scientists prefer to work. The numerals on the scales are clear and easy to read. Precise alignment with facing vernier scales gives accurate resolution to 0.1 mm. Vernier scales can also be augmented with a digital LCD position readout similar to a digital Vernier caliper. This option extends the readable resolution to 10 microns.

Convenient for electrophysiology

The entire Stereotaxic frame including the dovetails, manipulator arms and base are electrically continuous. Grounding of the entire frame including the base plate can be accomplished by connecting the provided grounding stud to earth. This is ideal for electrophysiological studies where the animal and surrounding structures need to be grounded to reduce electrical noise.

Included components

The standard Stereotaxic Frame System for cats and monkeys included parallel rail Stereotaxic frame, 17”x13” base plate, manipulator(s), cat/monkey adaptor, 18 degree ear bars, and swivel mount.
