The Epilor Plastic Loss of Resistance (LOR) Syringe is designed to help achieve greater success in detecting the epidural space. Optimized stopper design and stopper material aids in improving sensitivity and reduces the chances of air or saline from leaking around the stopper which can lead to false detection of the loss of resistance (LOR). Stablized plunger rod design and a positive plunger rod stop provide stability and prevent "plunger wobble" that could cause leaking around the stopper and hinder detecting loss of resistance.Other important features include: Latex Free construction, enhanced graphics and a clear barrel, textured plunger rod and thumb pad resulting in an ergonomic design for ease of use.
