Description
neochrom® Screw cap ND8 is a black polypropylene screw cap for ND8 thread vials, provided with a central hole of 5,5 mm diameter. Caps are supplied without septa, allowing laboratories to choose and mount the septum material that best fits the analytical method and sample matrix. The ND8 format is widely used for small sample vials in chromatography, autosampler work and general laboratory sample handling. Polypropylene gives a durable, lightweight closure for everyday use on the bench and on instruments. Packaged as 100 pieces per pack, the product supports routine series work and method development without excess inventory. Closures in this neochrom® range from manufacturer neolab - Labor are intended for combination with matching unmounted ND8 septa and corresponding screw-thread bottles. The open-hole design enables needle access once a suitable septum is fitted, which is useful for GC and HPLC injection workflows. A practical consumable for analytical, research and quality-control laboratories standardising on ND8 vial systems.

Questions about neochrom® Schraubkappe ND8, PP, mit Loch 5,5 mm, 100 Stck./Pack
What is this article?
neochrom® Schraubkappe ND8, PP, mit Loch 5,5 mm, 100 Stck./Pack is the article on this page. Luminix Health distributes neolab 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.
