Stoelting’s Large Parallel Rail Stereotaxic Instrument is designed for large animals but can be used on almost any laboratory animal when used with Stoelting’s selection of animal species adaptors. Includes Parallel Rail frame, dog/monkey adaptor, two 100 micron 2-axes manipulator arms (1 right-hand, 1 left-hand), traditional (18˚) ear bars, swivel stand, base plate, and four corner clamp probe holders.

For use with dogs, monkeys and other large animals.


  • Reliable Locks
  • Laser Engrave Scales
  • Exceptionally Accurate
  • Versatile
  • Affordably Priced
  • Holds up to six manipulator arms
  • Works with a large range of animals
  • AP Microdrive available for fine control of A-P axis

The Large Parallel Rail Animal Stereotaxic Instrument, manufactured by Stoelting, provides superior performance. Up to six manipulator arms may be conveniently positioned on the two parallel rails. Thus, several probes may be independently positioned in one animal.

Reliable Locks
If it is necessary to tilt the stereotaxic frame to gain access to the animal’s side or underside, the tilting and angling universal joint on Lab Standard™ manipulators have the most secure, reliable locks of any stereotaxic instrument.

Easily Read Scales
Precise, laser engraved graduations allow vernier scales to be aligned to 0.1 mm. The scales are oriented to enhance readability from common user positions. Standard manipulator arms have 100 micron resolution, while high-quality digital arms have a resolution of 10 microns.

Other species adaptors, probe holders and ear bars manufactured by Stoelting may be used on the 51800 series of stereotaxic instruments allowing for use with a wide range of animals and procedures.

A/P Microdrive Available

The optional 51858 Anterior/Posterior Microdrive provides fine movement control in the A/P dimension with 25 mm range and 10 micron graduations. The 51858 mounts between the rail and the manipulator and includes a longer probe holder shaft for the extra height. (See picture above.)
