The auxiliary EB-6 Ear Bars; non-rupture type with the aim of avoiding the stress on mice. The design does not let the eardrum punctured and the ear tube injured. The user saves the recovery time for perforated eardrum/ injured ear tube, and quickly move onto the next procedure of imaging/ recording. The angle of two points are dull, thus easier to find the ear tube without bleeding by injuring the skin inside. This non-rupture type will be a practical use for chronic/ awake experiments.
* Applicative to mice from 8 to 20 weeks old.
