The burette and filter set is equipped with a stop plug which has the function of stopping the main fluid output. Safety is guaranteed and improved, and there is a reduction in the risk of fluid leakage and spillage, during and after line initiation. The 15 Micron bacteria filter, inserted in the air vent, retains potential particles. The product is Latex Y-site free and contains wings for in-line injection and for protection of the user's fingers. In addition, it has a floating shut-off valve, a rotating Luer-Lock and burette markings are very easy to read. Its extra-sharp peak for easy perforation of the bottle with wings allows correct handling.
