Description
BTO Septa N 11,5, CenterGuide (TM) are gas chromatography septa with a diameter of 11,5 mm, intended as accessories for GC instrumentation and related analytical setups. Each pack contains 25 pc(s) of these BTO septa featuring the CenterGuide (TM) design, supporting consistent placement during routine injector maintenance and sample introduction work in the laboratory. With a net weight of 0,030 kg per pack, the format suits facilities that stock consumable GC parts in defined unit quantities for continuous instrument readiness. These septa belong to the chromatography accessories range and are positioned for gas chromatography workflows where an N 11,5 size is specified by the inlet or method documentation. The products are available from manufacturer Carl ROTH as part of its GC accessories portfolio for analytical laboratories. Operators performing separations can use the 11,5 mm diameter format wherever instrument configurations call for this septum dimension, helping to keep spare parts aligned with hardware requirements. Clear sizing together with the CenterGuide (TM) designation assists staff in matching replacements to existing injector hardware without ambiguity during ordering or service. The 25-piece pack supports ongoing method work, system checks and day-to-day chromatographic operation in research, quality control and service environments that rely on gas chromatography.

Questions about BTO Septa N 11,5, CenterGuide (TM), Ø 11,5 mm, 25 unit(s)
What is this article?
BTO Septa N 11,5, CenterGuide (TM), Ø 11,5 mm, 25 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.
