Description
Anti-twist lock / pull ring for safety ground joints NS 29/32 is a specialised laboratory accessory for securing and releasing ground glass connections. These pull rings are manufactured from polyamide and offer very good sliding properties. Even force distribution enables firmly seated joints to be loosened safely, helping to protect glassware from damage during disassembly. The component is intended for use with safety ground joints and supports reliable handling of core and socket assemblies. Supplied under the DURAN® trademark from manufacturer Duran/DWK Life Sciences, each unit is a single piece with a net weight of 0,001 kg. Polyamide construction delivers the smooth glide characteristics needed for repeated assembly and release cycles. Typical laboratory application focuses on securing safety ground joints and the controlled loosening of stuck connections in research and analytical workflows. This lightweight accessory integrates readily into standard glassware setups that require anti-twist protection and safe joint management.

Questions about Safeguarding , for safety standard ground sockets
What is this article?
Safeguarding , for safety standard ground sockets is the article on this page. Luminix Health distributes DWK Life Sciences 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.
