Description
PE snap cap N18-SD is a transparent N 18 polyethylene snap lid supplied in a closed design for sealing compatible vials and containers in laboratory environments. Manufactured from PE as a solid, hole-free snap cover, it provides a simple mechanical closure without an integrated septum, making it suitable where a full barrier lid rather than needle access is required. The clear body allows visual checks of the fit and of the vial contents when the geometry of the vessel permits. Intended for N 18 snap applications, the closed N18-SD profile is used for sample protection, short-term storage and general lab handling where an open centre is not needed. Each pack contains 100 pieces from manufacturer Macherey-Nagel, supporting consistent replenishment of consumable closures. Choose this transparent PE snap cap when protocols call for a closed N 18 snap lid without perforation, offering a straightforward, colourless option for everyday laboratory sealing tasks alongside other N 18 accessories.

Questions about PE Snap cap N18-SCV, nH, tr
What is this article?
PE Snap cap N18-SCV, nH, tr 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.
