STERLING* Nitrile Exam Gloves provide excellent fit and feel compared to latex. The new nitrile formulation provides excellent comfort and stretch, without sacrificing barrier properties or durability. They also have an Acceptable Quality Level (AQL) of 1.0. That means STERLING* Nitrile Exam Gloves are significantly less likely to have critical defects than exam gloves that just meet the ASTM 2.5 AQL requirement.
