Description
Ground joint clips NS 10/19, green are laboratory clamps for securing standard taper ground glass joints of size NS 10/19 during assembly, reaction work and apparatus set-up. Manufactured from polyoxymethylene (POM) plastic, the clips combine light weight with reliable spring action to hold conical joints firmly without metal-to-glass contact. The maximum service temperature is 150 °C, which suits many routine heating and distillation arrangements below that limit. Colour coding in green supports quick visual identification of the NS 10/19 size on crowded benches and in teaching kits. These clips from manufacturer Marienfeld are supplied in packs of 10 pieces for glassware stores, organic synthesis laboratories and educational practicals. They are intended for standard laboratory ground-joint glassware where a simple, reusable plastic retainer is preferred over wire or screw clamps. Suitable for chemistry, life-science and general analytical workflows that rely on interchangeable NS joints.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Clamps for standard ground joints NS 10/19, green
What is this article?
Clamps for standard ground joints NS 10/19, green is the article on this page. Luminix Health distributes Marienfeld 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.
