Conical joint stopper borosilicate glass, NS 19/26, solid, octagonal grip

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.
