Flip 'n Fold™ Bags make sample collection simple, sterile, and secure. To use, just remove the tear strip above the wire closure, pull the two external grip tabs to open the bag to the desired size, and introduce your sample. The grip tabs ensure that the bag remains sterile by eliminating direct hand contact with the opening, minimizing the risk of contamination. After placing the sample inside, fold the bag three times, bend the wires, and the sample will be safely enclosed in an airtight, moisture-resistant seal.

Made from high-quality virgin polyethylene, Flip 'n Fold™ Bags offer excellent clarity and strength. They meet USDA, EPA, and FDA standards and are sterile, RNase-free, DNase-free, and non-pyrogenic. The stainless steel wire is covered with an extended PVC tab, preventing any exposure to sharp edges that could cause punctures, scratches, or tears in gloves.

Some sizes come with a white printed area, which allows for easy labeling without the need for additional tapes or stickers. This marking area ensures that labels remain visible, durable, and resistant to smudging. Despite their large capacity of up to 55oz (1600mL), these bags fold completely flat, making them easy to store while saving valuable space.
