Description
Joint clamp/Rotulex 13/5 is a laboratory clamp for securing Rotulex spherical joints of size 13/5. It holds the two halves of a ball-and-socket joint firmly together so that the connection remains closed under normal laboratory handling, slight pressure differences or apparatus movement. The clamp is sized specifically for the Rotulex 13/5 designation and is used wherever small spherical joints appear in compact glassware trains, micro-scale set-ups or side-arm connections. Supplied as 1 pc, it can be fitted directly onto matching Rotulex 13/5 joints without additional adapters. Spherical joint clamps of this type allow the angular freedom of the Rotulex system while preventing accidental separation of the joint during use. This joint clamp from manufacturer LAT forms part of the standard accessory programme for conical and spherical ground-joint glassware. It is intended for research, teaching and routine analytical laboratories that employ Rotulex 13/5 components. The clamp supports secure assembly and disassembly of apparatus and is selected according to the joint size marked on the glassware.

Questions about Articulated tong w. spring/Rotulex 13/5
What is this article?
Articulated tong w. spring/Rotulex 13/5 is the article on this page. Luminix Health distributes LAT 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.
