Standard with Mouse and Rat Adaptors
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
securehold 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
into which to insert the ear bars.
Stoelting’s Mouse/Neonatal Rat
Adaptor employs light, Delrin® Ear Bars with tapered points on
one end, and rubber tips on the other, to facilitate surgery on
mice and rat pups.
A unique feature permits ear bars
to be independently adjusted in height to level the skull.
Laser-engraved scales show the vertical positions of the ear
bars. A Tooth Bar and Nose Clamp secures the nose.
The Jaw Holder Cuffs fit over the
ends of the ear bars, replacing rubber tips, providing an
alternative non-invasive means of securing the animal’s head in
the stereotaxic stage. These options for “triple point” securing
of the animal’s head in this adaptor make it the most versatile
mouse adaptor available.
Set of two jaw holder cuffs are
included. Triple-point options for securing the animal's head
are also included.
