Description
Slip-on cap NR is a flexible rubber laboratory closure intended for quick covering of flasks, bottles, tubes and similar vessels in routine laboratory practice. Fabricated from rubber, the cap slips over the opening to form a practical temporary seal that helps limit dust ingress and simple contamination during sample handling, short-term storage or transport of non-pressurised contents. Each individual piece has a net weight of 0,0038 kg, keeping the item light and easy to handle even when many units are in use. The product is supplied in a pack of 100 pieces, providing a convenient stock quantity for research groups, teaching laboratories, quality-control benches and production support areas that consume stoppers regularly. Positioned among standard laboratory stoppers (cork, rubber, silicone and cellulose types), this slip-on design from manufacturer Deutsch & Neumann supports everyday sealing tasks without the need for ground-joint precision. The resilient rubber construction offers good grip and repeated use under normal ambient laboratory conditions. It is well suited to general chemistry, biology, analytical and educational workflows where simple, reliable closures are required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Slip-on cap NR
What is this article?
Slip-on cap NR is the article on this page. Luminix Health distributes Deutsch & Neumann 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.
