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.

With the UltraBond seal system, the cap and septum form a one-piece unit. This is achieved with a patented bonding process without the use of adhesives, avoiding any form of contamination of the sample.

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.
