Professional vial septa types

2005/9/1 · Different types are available, all with similar goals: easy penetration, minimal contamination, and a long lifetime. The problem is that, at higher temperatures, the septa will start to bleed. These are cyclic degradation products produced as a homologue series starting with D3 (three siloxane units in a circle) and proceeding up to D10–D12.

A pre-slit septa is ideal in applications requiring drawing 20% or more of the sample volume from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle.

Pierce the vial septa, then screw the needle into the vial by rotating the needle depth gauge. Maintain the injection port temperature below the maximum recommended temperature of the fiber. Conduct headspace sampling when ever possible to minimize extraction or carry over of high molecular weight compounds that coat the fiber.
