Description
Rotilabo® aluminium caps with septum combine an aluminium shell with a PTFE/silicone septum at Ø 20 mm for use on matching autosampler vials and sample bottles. They serve as everyday sealing accessories for laboratories that prepare, store and analyse liquid or related samples in vial formats. The PTFE/silicone liner supports reliable closure during sample handling and instrumental work where a consistent seal is important. Packs contain 200 pc(s), offering a ready stock level for high-throughput benches, shared instrument rooms and quality-control stations. The stated pack weight is 0,334 kg, so the units remain straightforward to store and distribute. Supplied under the Rotilabo® range from manufacturer ROTH SELECTION, these caps belong to the consumables category for autosampler vials and laboratory sample vessels. They suit vial systems designed for 20 mm aluminium caps with septum and fit smoothly into standard sample-preparation and analysis routines. Clear specification of diameter and septum type helps laboratories select the correct closure for their vial workflow without adding unnecessary claims beyond the stated construction.

Questions about Rotilabo® aluminium caps with septum, PTFE/silicone, Ø 20 mm, 200 unit(s)
What is this article?
Rotilabo® aluminium caps with septum, PTFE/silicone, Ø 20 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.
