Description
Poly stopper for NS 10/19 is a polyethylene ground-joint stopper intended for sealing laboratory vessels with a standard NS 10/19 joint. Manufactured from low-density polyethylene (LDPE), it offers a lightweight, practical closure for flasks and other glassware that require a matched plastic stopper rather than glass. The NS 10/19 size fits corresponding standard taper joints, supporting secure vessel closure to help reduce evaporation, dust ingress and accidental spillage during sample holding, reagent storage or intermediate process steps. Supplied in packs of 10 pieces from manufacturer Hirschmann, these poly stoppers suit laboratories that need economical, reusable PE stoppers for medium-small joint sizes across analytical, synthetic and educational work. LDPE material allows easy manual insertion and removal while providing general chemical resistance appropriate for many routine aqueous and organic laboratory uses. Choose this poly stopper whenever a reliable PE seal for NS 10/19 joints is needed as part of standard glassware accessory sets and everyday vessel-closing procedures.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about POLY STOPPER NS 10/19
What is this article?
POLY STOPPER NS 10/19 is the article on this page. Luminix Health distributes Hirschmann 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.
