Description
ND18 PE snap cap, 19,8×5,2 mm, transparent, closed is a polyethylene snap-on closure intended for ND18 laboratory vials and related sample containers. Measuring 19,8 × 5,2 mm, the transparent closed design provides a full top without an access opening, supporting secure covering during sample handling, short-term storage and workflow organisation. Polyethylene (PE) is a familiar laboratory polymer for snap caps used in analytical and general lab settings. The ND18 format helps laboratories keep compatible closures on hand for matching vial systems. Supplied in a multipack of 10 × 100 pieces (1000 pieces total), the caps from manufacturer Altmann Analytik suit routine replenishment in research, quality-control and sample-preparation environments. The closed transparent style allows visual confirmation of fit while maintaining a continuous seal surface. Clear dimensional data of 19,8 × 5,2 mm supports straightforward selection against existing ND18 inventories, reducing mismatch risk when standardising consumables across instruments and methods that rely on snap-cap vials.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about ND18 PE snapcap, 19.8x5.2mm, 10 x 100 pc
What is this article?
ND18 PE snapcap, 19.8x5.2mm, 10 x 100 pc is the article on this page. Luminix Health distributes Altmann Analytik 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.
