Description
Conical ground joint stopper NS 19/26 solid with octagonal grip disc is a precision laboratory sealing component manufactured from borosilicate glass 3.3. This solid stopper is dimensioned exactly for standard NS 19/26 ground joints, ensuring a secure fit on flasks, condensers, adapters and reaction vessels used in chemical synthesis, distillation and sample handling. The octagonal grip disc provides a firm, non-slip surface that simplifies insertion and removal even when gloves are worn or the apparatus is wet. Supplied as 1 pc(s) from manufacturer Brand, the stopper offers the chemical durability and thermal stability characteristic of borosilicate glass 3.3, making it suitable for routine organic and inorganic laboratory work. Its compact solid construction contributes to mechanical robustness while remaining lightweight at a net weight of 0,0306 kg. Packaging volume is 0,000049 m³, allowing convenient storage alongside other ground-joint accessories. The product originates from Germany and integrates directly into existing glassware assemblies without additional adapters, supporting efficient workflow in research, analytical and teaching laboratories that rely on standardised conical joints for leak-free connections.

Questions about Conical joint stopper borosilicate glass, NS 19/26, solid, octagonal grip
What is this article?
Conical joint stopper borosilicate glass, NS 19/26, solid, octagonal grip is the article on this page. Luminix Health distributes Brand 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.
