Description
Ring 100 mm I.D. with boss in galvanised steel is a sturdy laboratory support accessory designed for retort stands and similar apparatus. Featuring an 8 mm diameter rod section, three-point support surface and a nickel-plated brass screw, the ring provides stable placement for flasks, funnels or other round-bottom vessels during heating, filtration or reaction setups. The galvanised steel construction offers corrosion resistance suitable for typical laboratory environments while the boss enables secure clamping to standard retort rods. Manufactured by Usbeck, this support ring is intended for everyday use in teaching laboratories, research benches and preparative work where reliable height-adjustable support is needed. The three-point contact distributes load evenly, reducing the risk of tipping, and the nickel-plated brass screw allows firm yet adjustable fixation. With a clear 100 mm inner diameter, it accommodates a wide range of common glassware sizes and integrates easily into existing stand assemblies without additional adapters.
This article is part of Stand & rack accessories, in Stands, clamps & racks.

Questions about Ring 100 mm inside Ø with Bosshead
What is this article?
Ring 100 mm inside Ø with Bosshead is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Stand & rack accessories, inside Stands, clamps & racks, in Labware.
These are the extra rods, connectors, feet and labels that extend a stand or a rack. A right-angle connector is how a second rod leaves the first. The diameter has to match the rod already on the bench.
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.
