Description
Retort ring with opening and boss head, 150 mm, Premium Line is a laboratory support ring for mounting glassware and vessels on retort stands. The open-ring design with integrated boss head enables straightforward height adjustment and secure clamping on standard stand rods, while the 150 mm diameter offers a stable platform for flasks and similar round-bottom ware during heating, cooling, or reaction work. Constructed from iron with an epoxy resin powder coating, the ring is built for durable everyday use on the bench. Net weight is 0,250 kg, giving solid feel without excessive bulk. This Premium Line accessory from manufacturer Labbox is supplied as one piece and suits chemistry, biology, and teaching laboratories that need reliable scaffolding components. The epoxy powder finish supports resistance to typical laboratory wear, and the opening-plus-muffe arrangement simplifies assembly of flexible support setups where open access and a firm clamp are required.

Questions about Open ring retort support with bosshead, 150 mm, Premium Line
What is this article?
Open ring retort support with bosshead, 150 mm, Premium Line 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.
