Description
Ring 70 mm I.D. with boss, steel, galvanised is a laboratory stand ring for supporting glassware and apparatus on retort stands. It offers an internal diameter of 70 mm and is made from galvanised steel, providing a protective finish suited to everyday laboratory conditions. The ring incorporates an 8 mm diameter section with a three-point support surface that distributes load evenly and helps keep vessels stable during heating or reaction work. A nickel-plated brass screw secures the boss firmly to the vertical stand rod, enabling reliable height adjustment. This single-piece accessory from manufacturer Usbeck has a net weight of 0,210 kg and is ready for immediate use in teaching, research and quality-control laboratories. The galvanised steel construction combines mechanical strength with straightforward maintenance, while the three-point contact design reduces the risk of tipping. Compatible with standard retort-stand systems, the ring holds flasks, evaporating dishes and similar round vessels securely. Its robust build supports repeated daily handling wherever dependable apparatus support is required at the bench.

Questions about Ring 70 mm inside Ø with Bosshead
What is this article?
Ring 70 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.
