Description
Joint clamps made of PTFE, 24/29 are laboratory accessories designed to secure standard ground-glass joints of size 24/29 in assembled glassware. Each clamp is made from pure PTFE and features fully encapsulated steel springs, providing chemical inertness together with consistent mechanical retention. Full jacketing of the springs keeps metal away from the joint surface, reducing the risk of corrosion or scratching during repeated use. The pure PTFE construction is chemically inert and may be used at temperatures up to 280 °C, covering many heated and ambient laboratory applications. Delivered as a single piece with a net weight of 0,020 kg, this clamp from manufacturer Labbox is suited to distillation trains, reaction flasks, and other setups that employ the 24/29 joint standard. Its PTFE body remains easy to position and remove while resisting attack by common laboratory chemicals. As a laboratory equipment accessory, the clamp offers a dependable fastening choice when metal-only hardware would be unsuitable, helping maintain clean, stable connections between conical ground joints throughout everyday synthetic and preparative workflows.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Conical head clip, PTFE, 24/29
What is this article?
Conical head clip, PTFE, 24/29 is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Matériel de laboratoire.
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.
