The new Just For Mice™ Stereotaxic Instrument was developed for the expanding growth of research being conducted with knock-out and transgenic mice. This system is ideal for researchers in need of a versatile, reliable instrument for stereotaxic procedures with mice and other small rodents. It allows the user to perform surgical procedures on two mice at one time. Precision alignment when using the Just For Mice™ ensures accurate placement of electrodes, micropipettes, and other devices.

The Just For Mice™ is the only instrument especially for mice, and offers several advantages over competing "made for rat" instruments:

Dual Units: The Just For Mice™ is two stereotaxic instruments on a single base. The base is 10" x 17" and has two ear bar slots located on each side. A tooth bar and nose clamp secures the nose. A single manipulator arm controls mediolateral and vertical positioning via lead screws, and antero-posterior movement via dovetail slide movement, with 80mm of travel possible in each direction, allowing access to both ear bar locations.

Unique, light ear bars: Ear bars may be independently adjusted in height - a unique feature of this stereotaxic instrument - to level the skull. Laser engraved scales show the vertical positions of the ear bars. Model organisms with soft skulls, such as the mouse and the neonatal rat, are difficult to secure firmly in a traditional stereotaxic instrument. The stainless steel ear bars used for adult rats are too heavy to provide a secure hold without compressing the sides of the skull inward (which closes the airways and impedes blood flow). Further, the neonatal rat pup has no external opening of the auditory canal for inserting the ear bar points.
