Stoelting™ Mouse and Neonatal Rat Adaptor

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 fl ow). Further, the neonatal rat pup has no external opening of the auditory canal into which to insert the ear bars.

• Ear and bite bar heights can be independently adjusted to accommodate a wide range of ages and assist in leveling the skull
• 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
• 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
• Tooth bar and nose clamp secures the nose
• Length accommodates larger, more mature animals
• Specialized jaw holder cuffs securely clamp the zygomatic processes of the skull
• Jaw holder cuffs fit over the ends of the ear bars, replacing the rubber tips, providing an alternative non-invasive means of securing the animal's head in the stereotaxic stage
• Options for triple point securing of the animal's head in this adaptor make it exceptionally versatile
• Set of two jaw holder cuffs included
