Description
Screw cap, 24 mm PP, without septum, white, closed is a solid laboratory closure intended for screw-neck vials and bottles in analytical and general laboratory use. Fabricated from polypropylene (PP) in a white finish, the closed top provides a continuous cover without a pre-cut hole. The 24 mm thread is suited to standard laboratory glassware requiring a firm mechanical connection. This cap is supplied without a septum; lids without a septum are not leak-tight, so a suitable septum should be ordered separately whenever a sealed, chemically resistant interface is needed. The pack format is 10 × 100 pieces, totalling 1000 units, which supports bulk stocking for sample preparation, storage, and routine laboratory operations. Available from manufacturer Altmann Analytik, the closed design is useful where an unbroken top is preferred before a septum is added, or where temporary covering of vessels is required. It integrates into chromatography, environmental, and quality-control workflows that rely on interchangeable polypropylene screw closures and separately selected septa.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about 24mm PP Screw Cap, white, closed top, 10x100/PAK
What is this article?
24mm PP Screw Cap, white, closed top, 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.
