Description
Spherical joint clamp for KS 65 is a robust laboratory fastening device made from 18/8 steel and equipped with a locking screw to secure spherical ground joints reliably. Designed as a fork clamp, it matches Schliffgröße KS 64/40 dimensions commonly found on larger glassware components. With a net weight of 0,187 kg and supplied as one piece, the clamp provides a solid mechanical interface for spherical joint connections in experimental apparatus. The 18/8 steel material ensures good durability and resistance to typical laboratory atmospheres. Manufactured by Rettberg in France, this accessory facilitates precise positioning and stable retention of glass assemblies used in synthesis, distillation or vacuum work. The locking screw allows controlled tightening and quick release, reducing the risk of glass damage while maintaining firm contact. Suitable for research, process-development and educational laboratories, the clamp offers a straightforward means of fastening KS-series spherical joints without additional adapters or complex hardware.

Questions about Clamp for spherical joint size 65, 18/8 steel, with locking screw
What is this article?
Clamp for spherical joint size 65, 18/8 steel, with locking screw is the article on this page. Luminix Health distributes Rettberg 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.
