Description
9 mm PP screw cap, transparent, with hole and natural rubber red-orange/TEF septum is designed for secure, pierceable closure of short-thread chromatography vials. The clear polypropylene open-top cap allows visual confirmation of correct seating on the vial neck while the central hole provides needle access for autosamplers or manual injection. The laminated natural rubber red-orange/TEF septum combines an elastomeric rubber layer with a PTFE (TEF) facing toward the sample, a configuration widely used when reduced analyte interaction and reliable resealing are required. Packaged as 1000 pieces, the product supports continuous operation in busy analytical laboratories. These transparent screw caps from manufacturer Altmann Analytik match the common 9 mm short-thread finish and help laboratories keep a consistent closure system across HPLC and GC methods. The red-orange natural rubber side ensures mechanical resilience, while the TEF contact surface is preferred for many organic solvents and sensitive analytes. Suitable for routine sample preparation, storage and chromatographic analysis, this open-hole PP cap with rubber/TEF septum is a practical consumable for everyday laboratory vial work.

Questions about 9 mm PP screw cap, transparent, w/ hole, natural rubber red-orange/TEF transp.
What is this article?
9 mm PP screw cap, transparent, w/ hole, natural rubber red-orange/TEF transp. 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.
