Description
White screw caps for sample bottles N24 with silicone/PTFE septum without slit are intended for secure closure of laboratory sample vials in autosampler and general sample-handling applications. They are developed for reliable use with needles and are specially designed to achieve a proper seal, supporting stable system performance throughout analytical workflows. The white N24 screw format with a silicone/PTFE liner offers a practical combination of sealing elasticity and chemical resistance at the sample contact surface, suited to routine preparation and storage of liquid samples. Supplied in packs of 100 pieces from manufacturer ISOLAB Laborgeräte, the caps are packed in tamper-evident, transparent bags with a ziplock closure. Transparent packaging makes contents easy to recognise at a glance, and the ziplock permits the bag to be resealed tightly after opening so that remaining caps stay clean and orderly. These white N24 silicone/PTFE screw caps without slit fit laboratories that need consistent vial sealing, needle-friendly access and convenient resealable packaging for everyday sample vial work.

Questions about cap + septa - silicone / PTFE - without hole - for N24 vials
What is this article?
cap + septa - silicone / PTFE - without hole - for N24 vials is the article on this page. Luminix Health distributes ISOLAB 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.
