Description
Rotilabo® aluminium caps with septum are laboratory closures intended for secure sealing of autosampler and sample vials in analytical workflows. Each cap pairs an aluminium shell with a PTFE/silicone septum, supporting needle access while helping protect sample integrity during chromatography and related sample-handling steps. The 11 mm diameter matches common vial formats used in routine instrumental analysis and quality-control laboratories. Offered as a pack of 200 pieces with a pack weight of 0,061 kg, the set suits high-throughput benches that need dependable everyday stock. PTFE/silicone septa are widely selected for their chemical resistance profile and resealing behaviour after injection, making these caps practical for liquid chromatography sample preparation and general analytical chemistry. These Rotilabo® caps from manufacturer ROTH SELECTION integrate smoothly into labware ranges for autosampler vials and sample bottles. They support organised vial workflows where consistent closure quality and clean sampling matter, from method development through routine series measurements. Use them wherever aluminium crimp-style or compatible vial systems require a PTFE/silicone barrier for reliable short-term sample containment and transfer.

Questions about Rotilabo® aluminium caps with septum, PTFE/silicone, Ø 11 mm, 200 unit(s)
What is this article?
Rotilabo® aluminium caps with septum, PTFE/silicone, Ø 11 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.
