Sample bags are designed to withstand the paddle action of lab blenders.
All standard and closure bags are made of highly transparent polypropylene and have wide-sealed bottoms to prevent leaks. Bags with 4mil wall thickness are for analyses of firmer samples. Standard bags are made with heat-extruded virgin polyethylene tubing and feature a tear-off sterile barrier top to ensure sterility up to the time of use. Closure bags permit collection, transportation, blending, and storage of samples all within the same bag. They are available with regular wire or extra-strength flat wire closures. Some bags feature a write-on strip for easier sample identification.
