Whirl-Pak® Black Sterile Bags are engineered to provide superior protection for light-sensitive samples, delivering unmatched performance compared to other opaque bags on the market. Designed with built-in secure closure tabs and a durable opaque film, these bags help preserve sample integrity during collection, shipping, analysis, and storage. Ideal for pharmaceuticals, spinal fluid, amniotic fluid, seasonings, flavors, vitamins, marine life, and other liquid or solid samples, Whirl-Pak® Black Bags combine leak-proof reliability with aseptic collection features and trusted post-manufacturing sterilization. With easy write-on labeling, exceptional film strength, and compliance with USDA, FDA, HACCP, and EPA requirements, these sterilized bags provide dependable protection and convenience for laboratory, industrial, and field applications. The opening Tyvek® pull tabs are perpendicular to the bag's opening, keeping hands away for a safe, aseptic collection technique each time. To use, label the bag using the convenient write-on strip, tear off the top along the perforation, use the pull tabs to open the bag, then place the sample in the bag. To close, hold the bag by the tabs and whirl 3 to 4 times to create a seal, or fold the tab over tightly 3 to 4 times to close, then bend in the wire tabs or bring the two wire ends together and twist to close. The continuous perimeter seal ensures satisfaction during sample collection, and the trusted, puncture-proof closure tabs provide a sturdy grip and secure, leakproof closure. The capacity is measured when the bag is closed and the tab is folded over three times (volume and dimensions are approximate, ±5%). The shelf life is 5 years from the sterilization date on the sterility confirmation documentation.
