The Riester Uni I Otoscope is a compact, reliable diagnostic instrument designed to deliver clear, bright visualization of the auditory canal and tympanic membrane. Equipped with a 2.7V vacuum illumination bulb, the Uni I provides direct, focused lighting that enhances diagnostic accuracy in both routine and detailed otoscopic examinations.

Built for versatility, the Uni I features a removable 4x magnifying lens that conveniently swivels to either side, allowing clinicians to use instruments through the otoscope without obstruction. The removable cover glass enables the insertion of tools for procedures such as foreign body removal or wax extraction. When paired with a 9 mm speculum (not included), the Uni I Otoscope may also be used for nasal examinations, increasing its usefulness across ENT evaluations.

A sealed system for pneumatic otoscopy allows precise assessment of tympanic membrane mobility—an essential diagnostic function in cases of suspected middle ear pathology. The lamp can be replaced quickly from the front of the instrument, ensuring minimal downtime.

The included chrome-plated metal C-cell battery handle, featuring an easy-access battery compartment, provides excellent durability and balanced handling. Packed in a protective plastic carrying case with three reusable ear specula, this otoscope set is ideal for clinics, general practitioners, ENT specialists, and mobile health providers.
