Description
Sample tubes in PFA with matching PFA screw cap offer a nominal volume of 15 ml and a clear ring mark at 10 ml for convenient volume reference during sample handling. Manufactured from perfluoroalkoxy alkane (PFA), these tubes combine chemical inertness with a smooth, non-wetting surface that supports clean transfer and recovery of liquids in analytical workflows. The integrated screw closure provides a secure seal for transport and short-term storage of samples destined for autosamplers or general laboratory processing. Supplied as single pieces from manufacturer Vitlab, the tubes fit typical sample-vial and autosampler-glass categories used in trace analysis, environmental testing and quality-control laboratories. Their all-PFA construction makes them suitable where metal-free or highly resistant sample containers are required. The 10 ml ring mark aids rapid visual checks without additional measuring tools, while the 15 ml capacity leaves headspace for mixing or dilution steps. Compact and robust, these PFA sample tubes are a practical choice for routine and specialised sample preparation tasks.

Questions about Sample tube, PFA, 15 ml, with screw-cap and ring-mark at 10 ml
What is this article?
Sample tube, PFA, 15 ml, with screw-cap and ring-mark at 10 ml is the article on this page. Luminix Health distributes Vitlab 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.
