High Purity Septa
High purity septa from SeptaSource has ultra low bleed (ULB).
Do you perform GC/MS, LC,MS, or other highly sensitive analytical testing? Then you need little or no interference peaks on your chromatographs. Unfortunately, standard PTFE/silicone septa just can’t deliver the results that you need.
Ultra Low Bleed Septa
Specialty Silicone Products, Inc. (SSP) understands the criticality and importance of your need for a high purity, ultra low bleed (ULB) septum.
That’s why we have specifically designed our ULB septa to use the highest purity silicone rubber and PTFE film, in conjunction with a rigorous curing and conditioning process.
Wouldn’t you prefer to get get septa that are virtually analytically pure? That’s why you need SeptaSource.
What Does “Ultra-Low Bleed” Mean?
Bleed refers to the release of volatile or semi-volatile compounds from the sealing material into the sample. Ultra-low bleed materials minimize this contamination, which is essential in sensitive analytical techniques like GC-MS (Gas Chromatography-Mass Spectrometry) or LC-MS (Liquid Chromatography-Mass Spectrometry).
Ultra Low Bleed Septa With or Without Caps
These clean, pure septa are available inserted into a wide range of screw, snap and crimp caps. We can also provide these septum by themselves, without a cap.
These high purity septum are available bonded into 9mm screw caps, 13-425 screw caps, and 24-414 screw caps. These high purity, ultra low bleed septum are unmatched
High Purity Septa ISO 9001:2015 Quality
All our septa are Made in the USA at our ISO 9001:2015-certified facility in Ballston Spa, New York facility.
