Description
Conical ground joints NS 19/26 are standardised laboratory joint cores produced in accordance with DIN 12249 for secure coupling of glassware. The NS 19/26 size defines a mid-range cone commonly used on reaction flasks, condensers, and intermediate adapters in organic synthesis, distillation, and general analytical work. Supplied as the Kern (core) variant, the piece forms the male ground cone that engages a corresponding NS 19/26 socket, enabling interchangeable assemblies across modular laboratory setups. Pack size is one piece, so individual joints can be stocked or replaced as apparatus configurations change. Compliance with DIN 12249 supports dimensional consistency and cross-compatibility with other components that follow the same standard. These conical joints from manufacturer Schlee are intended for routine laboratory material use in research, teaching, and quality-control environments. The NS 19/26 format balances working volume and handling convenience, making it a frequent choice for medium-scale glass trains where reliable, standardised ground connections are required without departing from established NS geometry.
