Has the optimal viscosity to stay in place and protect the urethra. The single-handed design allows the user to break the tip with one hand only, which maintains sterility. Allows you to instill lubricant with low initial pressure into the urethra. This steady pressure gently unfolds the urothelium, providing an even coating that reduces friction during catheter insertion. The syringe sits comfortably in the fingers, making it easy to grip, position, and depress.
