Description
Retort rings with boss head, approx. 70 mm Ø are laboratory support rings fitted with a boss head for attachment to stand rods. They form part of standard laboratory materials used to hold round-bottom flasks, funnels or heating baths at a chosen height on a retort stand. The approximate 70 mm diameter provides a practical working size for common glassware in research, teaching and routine laboratory workflows. Each item is supplied as 1 pc, suitable for building new assemblies or replacing individual rings. From manufacturer Hecht, these retort rings combine the circular support surface with an integrated boss head (muffe) so the ring can be clamped directly onto a vertical stand rod and adjusted as needed. Their role is mechanical positioning and support during heating, filtration or reaction steps that require a stable circular platform. Clear diameter indication helps laboratories match the ring to flask size and maintain consistent bench setups. As fundamental stand accessories they contribute to safe, organised experimental layouts without unnecessary complexity.
This article is part of Clamps & bossheads, in Stands, clamps & racks.

Questions about Rings for stands with bosshead ca. 70 mm Ø
What is this article?
Rings for stands with bosshead ca. 70 mm Ø is the article on this page. Luminix Health distributes Hecht 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.
