Ultra low bleed EPA VOA septa minimize the contamination associated with bleed, the release of volatile or semi-volatile compounds from the sealing material in the sample.
These high purity septum are available inserted into a wide range of screw, snap and crimp caps. We can also provide these septum by themselves, without a cap.
The clean silicone septa are made of platinum-cured silicones with low levels of extractables. They are used in sensitive analytics techniques like GC-MS (Gas Chromatography-Mass Spectrometry) or LC-MS (Liquid Chromatography-Mass Spectrometry).
