Description
neoChoice sleeve stopper 25 mm ø NS 24 is a silicone laboratory stopper designed for absolute tightness even on imperfect or slightly damaged glass rims. Folding the rim over the joint creates a firm, secure seat on standard NS 24 ground joints, preventing accidental loosening during handling or storage. Material can be withdrawn simply by piercing the silicone body with a needle or cannula, allowing repeated sampling without fully opening the vessel or compromising the seal. These flexible stoppers from manufacturer neolab - Labor under the neoChoice range offer reliable elasticity and chemical compatibility for everyday use with flasks, bottles and reaction vessels. The 25 mm diameter model is supplied in a practical pack of 10 pieces, making it a convenient stock item for laboratories that standardise on NS 24 glassware. Suitable for preparative chemistry, sample storage and multi-step procedures, the stoppers help maintain closed systems, reduce evaporation losses and limit contamination risks in both teaching and research environments.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about neoChoice folding stopper 25 mm ø NS 24 silicone VE 10 pieces Nr. 1-1037
What is this article?
neoChoice folding stopper 25 mm ø NS 24 silicone VE 10 pieces Nr. 1-1037 is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
