Description
Joint clamps Safety Clip NS 34/35 are polymer fastening clips for securing standard ground glass joints in laboratory glassware assemblies. Made from POM, they are sized for NS 34/35 conical joints and help keep flasks, condensers, adapters and related components firmly connected during routine setup, reaction and distillation work. The Safety Clip design supports quick attachment and release without tools, which is useful when glassware configurations change frequently. Each pack contains 10 pc(s) and has a total weight of 0,190 kg, making the set practical for bench stock and shared laboratory stores. These joint clamps from manufacturer Lenz fit the stoppers-and-clamps category used across teaching, research and quality-control laboratories. POM construction keeps the clips lightweight yet mechanically stable for everyday handling of ground-joint apparatus. Matching the widely used European NS 34/35 format, they support standardized glassware trains and consistent joint security where a polymer clip is preferred over metal alternatives.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Joint clamps Safety Clip, NS 34/35, POM, 10 unit(s)
What is this article?
Joint clamps Safety Clip, NS 34/35, POM, 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.
