Made of heavy-duty polyethylene tubing that includes a secured wire tie to provide adequate closure. These bags are ideal for environmental sample collection, food testing, or sample enrichment. These tough bags are designed to meet stringent laboratory testing needs and have the strength needed to endure the sample preparation process. The writable area is ideal for documenting data, date, time of collection, and other information. The tear-off top ensures the inside of the bag is free of contamination until ready for use. Once the desired sample has been added, the open top is folded over itself and then the wire tie is bent over the fold to keep the contents of the bag from leaking.
