These white polypropylene (PP) caps and EPA septa are free of substances that might influence sample analysis for testing of potentially harmful environmental contaminants in water or soil samples. Select from septa only, cap only, or cap and septa combination.

Please Note: Vials, caps, and septa formerly under the Kinesis brand have now been rebranded Cole-Parmer. All the same great features and specifications, just with a new and improved look.
