Unique Vial Cap Septa

Unique Vial Cap Septa

In scientific laboratories, failed seals can wreak havoc, causing wasteful re-testing, or worse, misleading results. Yet recent years have seen few new ideas. At Pawling EP, we are working hard to change this.

Our Cepure line of vial cap septa offers new septum materials and unique processes to improve septum sealing integrity and reduce the risk of sample contamination. Examples include the Zero injection port septa, NT line of low bleed silicone autosampler vial cap septa, and NR line of natural rubber aluminum crimp cap vial septa.

What Makes Us Different?

Our experience with and knowledge of different materials gives us an edge. Over the years, we have worked with all types of silicone, organic polymers (e.g. Natural Rubber and Butyl), and different types of plastics too. Our focus is to develop the best possible formulation for the application. We welcome custom inquiries for unique vial cap and injection port septa, especially when the standard parts in the marketplace won't do.
