Description
Rotilabo® aluminium caps with septum are closure components for laboratory sample vials used in autosampler and analytical workflows. Each cap has a diameter of 13 mm and incorporates a PTFE/silicone rubber septum, combining an aluminium shell with a dual-layer sealing disc suitable for vial sealing in chromatography sample handling. The PTFE face provides a chemically resistant contact surface toward the sample, while the silicone rubber layer supports resealing performance typical of septum closures in liquid chromatography environments. These caps are intended for use with matching autosampler vials and sample bottles where a 13 mm aluminium crimp or seal format with PTFE/silicone rubber septum is specified. Supplied in a pack of 200 pieces from manufacturer ROTH SELECTION, the unit weighs 0,087 kg and supports laboratories that process many sealed samples in sequence. Rotilabo® aluminium caps with PTFE/silicone rubber septa fit standard labware sets for autosampler vials, HPLC sample preparation and related LC applications. They help maintain consistent closure geometry across sample series when 13 mm aluminium caps with PTFE/silicone rubber septa are required. A practical bulk pack for routine analytical and chromatography sample sealing.

Questions about Rotilabo® aluminium caps with septum, PTFE/silicone rubber, Ø 13 mm, 200 unit(s)
What is this article?
Rotilabo® aluminium caps with septum, PTFE/silicone rubber, Ø 13 mm, 200 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
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.
