Description
Conical joint clamp for joint size NS 29 is a nickel-plated spring steel laboratory clamp engineered to secure conical ground-glass joints reliably during assembly and operation. Fabricated from resilient spring steel with a protective nickel coating, the clamp withstands demanding thermal conditions and is expressly suited for applications at very high temperatures above 150 °C. It provides firm, vibration-resistant fixation of NS 29 joints in distillation, reaction and heating apparatus, helping maintain leak-tight connections under elevated thermal load. The robust construction supports repeated use in chemical synthesis, analytical workflows and process development where glassware must remain securely joined. Supplied as a single piece from manufacturer IDL GmbH, this conical joint clamp integrates easily into standard laboratory setups that employ NS 29 ground joints. Its corrosion-resistant surface finish and high-temperature capability make it a practical accessory for research laboratories, teaching facilities and industrial environments requiring durable joint retention without compromising glassware integrity.

Questions about Ground glass joint clamp for ground joint, NS 29
What is this article?
Ground glass joint clamp for ground joint, NS 29 is the article on this page. Luminix Health distributes IDL GmbH 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.
