| Features The WPI Mouse
and Neonatal Rat Adaptor employs light, Delrin®
ear bars with tapered points on one end and
rubber pads on the other to facilitate surgery
on mice and rat pups.
Adjustable ear bars
Ear bars may 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. A
well in the thick aluminium body may be filled
with dry ice and alcohol for hypothermic
anaesthesia of neonatal animals. The 502063
Adaptor clamps securely on the right side of the
“U” frame of the stereotaxic instrument.
Why it works
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 into
which to insert the ear bar points. The
specialized jaw holder cuffs (502080) securely
clamp the zygomatic processes of the skull. The
jaw holder cuffs fit over the ends of the ear
bars, replacing the rubber pads, 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 stereotaxic available. Set of
two jaw holder cuffs included.
