Beschrijving
Conical joint sleeve NS 5/13 is a standardised laboratory ground-joint component for interchangeable glassware connections in the NS system. Defined as a female socket (Hülse) to DIN 12249, it provides the conical interface needed to couple matching male cones of the same nominal size in modular apparatus. The NS 5/13 designation identifies a compact joint format suited to smaller-scale assemblies where space and bore must remain limited. Offered as a single piece from manufacturer Schlee, the sleeve supports routine build-up, repair and expansion of jointed glass setups used across general laboratory work. When mated with a corresponding NS 5/13 cone, the ground conical surfaces form a stable, reusable seal that helps maintain alignment of flasks, adapters and related components without non-standard fittings. Laboratories that maintain DIN-compliant glassware collections can integrate this socket directly into existing kits for teaching, preparation or analytical tasks. Clear size marking and adherence to the established NS geometry simplify selection and replacement. Packaged as one piece, the item is convenient for stocking individual joint sizes or completing incomplete apparatus sets.
