Description
Septa with a diameter of Ø 16 mm, thickness 1,7 mm and hardness 45° are laboratory sealing discs for autosampler vials and sample-bottle caps. Each septum is a silicone blue transparent/PTFE white laminate: a softer silicone body at 45° hardness with a white PTFE barrier layer for chemical resistance at the sample interface. The 16 mm diameter and 1,7 mm thickness address closures that need a slightly thicker, lower-hardness liner than standard hard butyl options. Packs of 1000 pc(s) weigh 0,478 kg, giving ample stock for method development, routine analysis, and consumable replacement. These silicone/PTFE septa from manufacturer ROTH SELECTION fit vial and cap systems specified for Ø 16 mm liners in the autosampler-vial category. Combining transparent blue silicone with white PTFE, defined thickness, and 45° hardness, they offer a clear specification match for laboratories that standardise on this septum geometry for reliable sealing and needle access in everyday sample handling.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Septa Ø 16 mm, thickn. 1.7 mm, hard. 45°, silicone blue transparent/PTFE white
What is this article?
Septa Ø 16 mm, thickn. 1.7 mm, hard. 45°, silicone blue transparent/PTFE white is the article on this page. Luminix Health distributes Carl Roth 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.
