Description
High-temperature septa N 11 HT are specialised sealing discs intended for chromatography and sample-handling setups that operate under elevated temperature. Each septum features an outer diameter of 11 mm and a thickness of 3 mm, matching N 11 closure formats and related inlet or vial interfaces. Packaged in units of 50 pieces, they support laboratories that replace septa regularly to preserve seal quality and reduce contamination risk between runs. These high-temperature septa from manufacturer Macherey-Nagel are chosen where ordinary septa may lose elasticity or generate bleed under thermal stress. The controlled outer diameter and thickness promote consistent seating and predictable needle penetration across sequential injections. At a net pack weight of 0,03 kg, the product is convenient to stock and dispense at the bench. Apply them in analytical workflows that demand dimensional accuracy together with improved thermal endurance for reliable sample sealing throughout routine laboratory use.

Questions about High temperature septa N 11 HT
What is this article?
High temperature septa N 11 HT is the article on this page. Luminix Health distributes Macherey-Nagel 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.
