Micro Packaging Vials
Nalgene Plastic Micro Packaging Vials are molded from high purity, low-metal content polypropylene copolymer resin. Micro Packaging Vials are skirted with conical interiors to allow recovery of entire contents. Both vials and closures are pressure-tested together for air shipment and meet the requirements of FDA CFR21 177.1520 for food and beverage use, USP Class VI and are non-pyrogenic. Colored closures are either packaged separately from Micro Packaging Vials or as a set; please read product descriptions carefully.
