The 11mm crimp sample bottle strictly controls the bottle mouth specifications. The precision-shaped bottleneck can improve the processing capacity of the autosampler. It is 40% larger than the bottle mouth of the standard narrow-mouthed sample bottle. Strict quality assurance provides the size between batches. Consistency, a uniform flat bottom can ensure matching with the inner cannula. In order to ensure good function, it can be slit in advance to facilitate needle penetration. It is designed for single injection or short sampling cycle. It is especially suitable for liquid chromatographs. It ensures that the septum will not fall into the sample bottle during the sampling process. This septum is made of PTFE/silicone fusion, they have excellent inertness and can be used for multiple injections. The thickness of the 11mm septum is 1mm, and the PTFE is about 0.1mm.
