    Certified Clean LP Bottles

    021A-125 & 021A-250 & 021A-500 & 021A-1000 & 021B-125 & 021B-250 & 021B-500 & 021B-1000

    Batch Certified Clean LP Bottles

    Designed as a clean sample bottle for most particulate testing applications, this container is suitable for most sample fluids. Before filing, please consult material compatibility charts for HDPE and PP for your specific material.

    Using an appropriate sampling plan, a sample set of bottles from each batch is filled with particle-free water and tested. The entire batch of bottles is certified clean if the mean particle count ≥ 0.7 µm in that sample set is not more than 10 particles/mL.

    Individually Certified Clean LP Bottles

    Designed as a clean sample bottle for most particulate testing applications, these HDPE containers with PP caps are suitable for most sample fluids. Before filing, please consult material compatibility charts for HDPE and PP for your specific material.

    By ordering this option, each bottle is filled with particle-free water and tested individually. The bottle is certified clean if the mean particle count ≥ 0.7 µm is not more than 10 particles/mL.

    Includes individual C of A for each bottle along with particle test report.
