Description
Conical ground joint NS 45/40 is a standardised male core (Kern) ground connecting element for laboratory apparatus. Manufactured to DIN 12249, the NS 45/40 taper defines the larger diameter and ground length of the cone so it mates interchangeably with matching female sockets of the same nominal size. This single-piece conical joint supports construction and maintenance of larger glassware assemblies, including wide-neck flasks, condensers and process adapters that require a defined ground seal. DIN 12249 geometry ensures consistent fit and sealing-surface contact along the ground zone when paired with compatible sockets. The NS 45/40 size is typical for higher-capacity or larger-bore laboratory setups in preparative and distillation work. These conical joints from manufacturer Schlee form part of the essential labware range used to couple apparatus in teaching and research environments. Pack size is one piece, enabling targeted replacement or extension of existing joint inventories. Choosing the correct NS designation maintains interchangeability across multi-component glass trains that rely on DIN conical joints for reliable mechanical and sealing performance under standard laboratory conditions.
