Beschrijving
Conical ground joint NS 34/35 is a standardised male core (Kern) connecting element for laboratory glass apparatus. Produced according to DIN 12249, the NS 34/35 taper specifies the larger diameter and ground length of the cone, enabling interchangeable mating with female sockets of the same nominal size. Supplied as a single piece, this conical joint is used to build or maintain modular assemblies such as reaction flasks, condensers and transfer adapters where a defined ground seal is needed. DIN 12249 geometry keeps cores and sockets aligned so that sealing surfaces contact correctly along the ground zone. The NS 34/35 size suits medium-to-larger apparatus common in preparative and distillation work. These components from manufacturer Schlee belong to the core labware fittings range for teaching and research laboratories that standardise on conical ground joints. One-piece packing allows precise replenishment of individual sizes without overstocking full sets. Correct NS selection preserves interchangeability across multi-neck flasks, still heads and vacuum lines that depend on DIN conical joints for reliable coupling under normal laboratory practice.
