Description
BOLA Combi nuts ''SAFE LAB'', NS 29/32 PTFE-glass fibre provide a firm and secure link between ground joint core and socket while allowing straightforward separation when needed. Guided on an external thread above the ground joint core, the combi nut retains the socket and secures the connection in one step. If a ground joint has seized, turning the combi nut clockwise transfers finger force axially through the thread pitch onto the socket and frees the joint without aggressive prying. The nut is sized for standard ground joint NS 29/32 and is manufactured from polytetrafluoroethylene (PTFE) with glass-fibre reinforcement. Net weight is 0,035 kg per unit. Pack size is 1 pc. These laboratory fittings from manufacturer Bohlender support reliable handling of medium-size normschliff assemblies in chemical and analytical work. They are suited to glassware setups that demand both stable joint retention during use and controlled release after reaction or distillation steps involving standard taper joints.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about BOLA Safe-Lab'' Nuts '', NS 29/32 glass-fibre reinforced PTFE
What is this article?
BOLA Safe-Lab'' Nuts '', NS 29/32 glass-fibre reinforced PTFE is the article on this page. Luminix Health distributes Bohlender 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.
