Description
Retort ring with opening and boss head is a laboratory support accessory designed for secure mounting of round-bottom flasks and similar vessels on a retort stand. Manufactured from chrome-plated steel, the ring combines mechanical stability with a durable surface finish suited to everyday bench use. The 120 mm diameter provides a generous seating area for medium-sized glassware, while the integrated opening allows easy placement and removal of flasks without lifting the entire assembly. A built-in boss head enables direct clamping to a standard support rod, keeping the setup compact and adjustable in height. This configuration is typical for heating, distillation, extraction and general preparative work where reliable vessel support is essential. Supplied as a single piece from manufacturer Labbox, the ring has a net weight of 0,189 kg and fits standard laboratory scaffolding systems. Its chrome-plated steel construction offers corrosion resistance under normal laboratory conditions and a smooth finish that is straightforward to clean. Ideal for teaching laboratories, research benches and routine analytical workflows requiring dependable flask support.

Questions about Open ring retort support with bosshead, chromium plated steel, Ø 120 mm
What is this article?
Open ring retort support with bosshead, chromium plated steel, Ø 120 mm is the article on this page. Luminix Health distributes Labbox 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.
