Description
Screw cap ND13 PP without septum is a white, closed polypropylene closure for laboratory vials and related sample vessels with an ND13 neck finish. This solid-top screw cap is supplied without a septum, allowing laboratories to specify and install the sealing disc that matches their solvent compatibility, temperature range or analytical workflow. Caps without a septum do not seal tightly on their own; a compatible septum should be ordered separately whenever leak-tight closure is required for storage, transport or analysis. The white polypropylene body offers a clean, clearly identifiable closed top until the chosen septum is fitted, supporting organised bench and inventory practices. Packed as 10×100 pieces for a total of 1000 pc(s), the product suits routine replenishment of ND13 consumables. From manufacturer Altmann Analytik, it provides a straightforward closed ND13 option for users who prefer to manage cap colour, neck finish and septum selection as independent components within their sample-preparation setup.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about ND13 PP Screw Cap, white, closed, 10x100/PAK
What is this article?
ND13 PP Screw Cap, white, closed, 10x100/PAK is the article on this page. Luminix Health distributes Altmann Analytik 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.
