Description
Septum with 10 mm diameter in white silicone laminated with red PTFE and 1,3 mm thickness is a laboratory sealing disc for vial and closure systems that require this diameter and laminate construction. The white silicone layer provides resilient sealing, while the red PTFE face offers an inert sample-contact surface typical of analytical septa. At 1,3 mm overall thickness and 10 mm diameter, the disc is suited to matching caps and vials specified for these dimensions. Packs of 1000 pieces support high-volume sample preparation and routine instrument workflows. This silicone/PTFE septum from manufacturer Altmann Analytik corresponds to the Labhut Cronus reference VCS-1004-1000 for users aligning consumables across suppliers. It is intended for chromatography and general laboratory sealing tasks where a white silicone / red PTFE laminate at 10 mm diameter and 1,3 mm thickness is specified, delivering consistent pack quantities for continuous bench use without additional performance claims beyond the stated construction.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Septa, 10 mm diameter, silicone white/PTFE red, 1,3 mm, 1000/pck
What is this article?
Septa, 10 mm diameter, silicone white/PTFE red, 1,3 mm, 1000/pck 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.
