Description
neochrom® screw caps ND24 white, closed, with PTFE/EPDM/PTFE septum are laboratory screw closures for secure sealing of compatible ND24 vials and sample bottles. Made from white polypropylene with a 24-400 thread, each closed cap is fitted with a multilayer PTFE/EPDM/PTFE septum that is PTFE-coated on both sides. Septum thickness is 2,0 mm, supporting a dependable barrier for sample integrity during handling and short-term storage in analytical workflows. The solid, non-perforated design suits applications where needle access is not required and contamination risk must be minimised. Pack size is 100 pieces per pack, convenient for routine laboratory use. These neochrom® closures from manufacturer neolab - Labor fit chromatography sample preparation, environmental analysis, and general wet-chemistry sealing tasks on matching neck finishes. White PP construction provides practical chemical resistance for many common aqueous and organic matrices. The defined PTFE/EPDM/PTFE stack offers a consistent sealing surface for laboratories that need standardised ND24 screw caps without an open centre hole.

Questions about neochrom® Schraubkappen ND24 weiß, geschl., Septum PTFE/EPDM/PTFE, 100 Stck./Pac
What is this article?
neochrom® Schraubkappen ND24 weiß, geschl., Septum PTFE/EPDM/PTFE, 100 Stck./Pac is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
