Description
Retort ring with boss head, 18/10 steel, ID=100 mm is a laboratory support ring for secure mounting of glassware and apparatus on retort stands. Fabricated from 18/10 stainless steel, it combines corrosion resistance with mechanical stability for everyday bench and fume-hood work. The ring provides an inner diameter of 100 mm and includes an integrated boss head, while the shaft length is 70 mm for compact attachment to standard stand rods. With a weight of 310,0 g (0,31 kg), the component is easy to position yet sturdy enough for typical heating, filtration, or reaction setups. This retort ring from manufacturer Bochem is supplied as a single piece and suits teaching laboratories, research groups, and quality-control environments that require durable stainless-steel stand accessories. Its 18/10 steel construction supports repeated clamping and release cycles, and the defined inner diameter helps centre flasks, funnels, or baths above burners or hot plates with consistent geometry.

Questions about Retort ring with bosshead 18/10 Steel, ID=100mm
What is this article?
Retort ring with bosshead 18/10 Steel, ID=100mm is the article on this page. Luminix Health distributes Bochem 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.
