Store and ship small-volume, light-sensitive samples using Thermo Scientific™ Nalgene™ Opaque Amber HDPE Diagnostic Bottles. Used in test kits and many small volume applications, the opaque amber color of these high density polyethylene (HDPE) sample bottles make them ideal for packaging light sensitive reagents. The durable, uniform walls are resistant to splitting or puncturing. Bottles and closures are packed in rigid shrink-wrapped trays, allowing for easy handling. Bottles include leakproof amber polypropylene (PP) caps that provide excellent chemical resistance. To ensure leakproof performance, use only the cap provided.
