The ENTity Difference
Freedom to Move. Precision to Diagnose.

The ENTity Series of Flexible Fiberoptic Nasopharyngoscopes revolutionizes the field of nasal visualization with its cutting-edge features and unparalleled portability. Traditional endoscopy tethers you to a light source and a stack. The ENTity XL series integrates a high-intensity LED light source directly into the handle, providing superior illumination without the weight or fragility of fiber-optic cables.
Rugged, Reliable, and Ready for High-Volume Use.
In the Canadian healthcare landscape, from busy metropolitan hospitals to remote community clinics, equipment downtime is not an option. The ENTity XL series is designed for durability:
Easy Disinfection
Compatible with STERIS Revital-Ox™ Resert®, Rapicide OPA/28, and Metricide OPA Plus.
Ergonomic Design
Balanced handle reduces wrist fatigue during long clinic days.
Portable Reliability
Ideal for bedside consults, speech pathology, and ER environments.
