Stoelting™ Lab Standard with 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 flow). Further, the neonatal rat pup has no external opening of the auditory canal into which to insert the ear bars.

• 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 secure the nose
• 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 usefully versatile
