Description
Coil spring ground-joint clamps are laboratory joint clips built around a coil-spring body for secure fastening of ground-glass connections. With a total length of 40 mm, they accommodate common joint geometries found in reaction trains, distillation columns and modular glassware. The spring action delivers steady holding force while allowing rapid placement or removal when apparatus must be reconfigured. Packaged as 10 pc(s), the product supports multi-user labs and routine restocking of joint accessories. Each clamp weighs roughly 0,011 kg, keeping storage and handling straightforward alongside other stoppers and clamps. These coil spring ground-joint clamps from manufacturer Lenz are suited to analytical, synthetic and educational environments that rely on ground joints for leak-resistant, reusable assemblies. They help maintain alignment of glass components during heating cycles, vacuum or inert-gas work and general bench operations where dependable, low-profile joint security is preferred over heavier mechanical clamps.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Coil spring ground-joint clamps, coil springs, total length 40 mm, 10 unit(s)
What is this article?
Coil spring ground-joint clamps, coil springs, total length 40 mm, 10 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
