The M5158 mouse ear rod combines the advantages of both 18 ° and 60 ° ear rods to achieve a set of ear rods that meet the needs of two different usage environments, and also reduces the risk of losing spare ear rods.

During the experiment, an 18 ° ear rod can be used, which is relatively easy to penetrate into the animal ear canal and convenient for fixing the skull; Alternatively, a 60 ° obtuse angle ear rod can be used to avoid situations where the thickness of the mouse skull is thin and prone to compression damage. It is designed to fix the mouse ear canal and is easy to use.
