Description
Short thread cap ND9 in red polypropylene with a 1,0 mm natural rubber red-orange/TEF transparent septum is designed for analytical vial sealing where dependable needle penetration and resealing matter. The natural rubber and TEF combination supports secure injection access in chromatography and related sample workflows. At 1,0 mm thickness the septum balances softness for reliable penetration with effective closure performance. The screw cap follows a crimp-cap style design, so it is also suitable for use with robot gripper arms in automated sample handling. Pack size is 1000 pieces for high-throughput laboratories. This product from manufacturer Altmann Analytik is listed as an alternative to Agilent 5182-0719, National Scientific C4000-51R, Wheaton W225331-0103, Finneran 5394-09R and SUN/SRI International 501 349. Red colour coding aids quick visual identification among mixed vial closures. The ND9 short-thread format fits standard short-thread vials used across many instrument platforms, making the cap a practical consumable for routine GC and LC sample introduction and laboratory sample containment.

Questions about ND9 PP Short Thread Cap, red, 1,0mm
What is this article?
ND9 PP Short Thread Cap, red, 1,0mm 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.
