World Precision Instruments Mouse And Neonatal Rat Adaptor

World Precision Instruments - For use with the 505211 wpi rat stereotaxic instruments and other stereotaxic instrumentsmodel 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.
