Description
DURAN® long ground joint socket, ground, NS 14/35 is a precision laboratory glass component fabricated from borosilicate glass 3.3. The long-joint variant provides an extended grinding surface and is frequently selected for high-vacuum service. A finely ground finish with reduced roughness depth supports reliable sealing and a dense closure through the standardised ground joint. The larger contact area makes the socket particularly suitable for high-vacuum applications and for integration into glass apparatus and laboratory devices as a glass article for further processing. Offered by manufacturer Duran/DWK Life Sciences, the component combines the chemical resistance and thermal stability of borosilicate glass 3.3 with dimensional consistency required for laboratory glassware construction. It enables secure, low-leak connections when paired with matching cones under demanding vacuum conditions. Supplied as a single piece with a net weight of 0,023 kg, this long ground joint socket is ready for assembly into custom glass systems where extended joint length and fine grind quality are advantageous.

Questions about DURAN® Long Ground Socket, finished
What is this article?
DURAN® Long Ground Socket, finished is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
