Our Zipper Biohazard bags are high-quality, reclosable bags with easy-grip tops! These specimen bags with zip top closures feature a biohazard symbol, liquid-tight closure, and some have temperature storage indicator check boxes. These bags are all two-wall construction, meaning they do NOT have a document pouch. Our two-wall zipper specimen bags come in convenient dispenser-style packaging with inner packs of 100. Our specimen bags can be custom printed with low minimum order quantities – call for details!
