Description
Aluminium crimp cap with silicone/PTFE septum is a chromatography accessory designed for secure sealing of crimp-neck vials with an 11 mm opening. The aluminium shell provides a firm crimp closure, while the silicone/PTFE septum supports reliable needle penetration and chemical resistance during sample injection and storage. Packaged as 100 pieces, these caps suit routine GC and HPLC sample preparation where consistent seal integrity is essential. Intended for vials with a crimp rim and 11 mm opening, the format matches standard laboratory vial systems used in analytical workflows. This accessory from manufacturer Labbox helps maintain sample integrity from preparation through analysis, reducing evaporation and contamination risks in busy chromatography laboratories. The silicone/PTFE combination is widely preferred for broad solvent compatibility and clean resealing behaviour after multiple injections. With a net weight of 0,050 kg per pack, the unit is convenient for stocking autosampler lines, method development benches, and quality-control sample sets. Ideal for analytical chemistry, environmental testing, and pharmaceutical laboratories that rely on 11 mm crimp vials for reproducible chromatographic results.

Questions about Aluminum crimp cap Ø11 mm with silicone/PTFE septum, 100 pcs
What is this article?
Aluminum crimp cap Ø11 mm with silicone/PTFE septum, 100 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Bouchons de vials & septa, inside Vials, bouchons & septa, in Chromatographie.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
