These sample bags are ideal for transportation and storage of solids, semisolids, and liquids. They are made of virgin polyethylene sterile tubing with no side seals. Bags feature a wire closure for an airtight seal and wide-sealed bottoms for added leakproof protection. They are easy to use: simply tear off perforated top, pull tabs to open bag, fill, grab ends of tape closure and pull shut, twirl bag three or four times to seal, and bend ends of closure inward to lock the seal.
Choose from four bag closures: a round wire closure with or without puncture-proof safety tabs, or a heavy-duty flat wire and round wire closure with or without safety tabs. The heavy-duty closure provides a stronger, more secure seal. Puncture-proof safety tabs eliminate the sharp points that can cause bag puncture and abrasion. Bags with white marking area allow for written notation.
Note: Do not use with alcoholic substances or where temperature exceeds 100°C (212°F).
