Description
Retort ring with rod and boss head is a complete laboratory support set comprising a retort ring, a connecting rod and a boss-head clamp for mounting on standard stands. Classified among retort-ring accessories, it enables secure, height-adjustable placement of flasks, funnels and related glassware during heating, distillation, extraction or general bench operations. The ring forms a circular support for round vessels, while the rod and boss head lock the assembly firmly to a vertical stand rod. Supplied as 1 pc, the unit is suited to outfitting single workstations or replacing worn support elements without ordering separate components. This assembly from manufacturer RSG is intended for chemical, analytical and educational laboratories that rely on stable, hands-free positioning of apparatus. It integrates readily into existing retort-stand frameworks and supports common workflows such as reflux, gravity filtration and temporary vessel holding. The combined ring–rod–clamp design keeps the support path short and mechanically coherent, helping maintain vessel alignment under ordinary laboratory conditions and simplifying day-to-day stand configuration.
This article is part of Clamps & bossheads, in Stands, clamps & racks.

Questions about Support ring with clamp
What is this article?
Support ring with clamp is the article on this page. Luminix Health distributes RSG for laboratory use. It sits in Clamps & bossheads, inside Stands, clamps & racks, in Labware.
A bosshead grips the rod. A clamp grips the flask or the condenser, usually through two jaws with cork or vinyl faces. Three-finger and two-finger clamps hold different shapes. The jaw opening is the specification.
A stand, a clamp and a rack hold something still so the hands can do the work. A bosshead locks a clamp to a rod. A test-tube rack keeps tubes upright and in an order the operator can read back. The failure is almost always mechanical: the clamp slips, or the rack does not match the tube diameter. The glass they support is indexed under ISO laboratory glassware.
