Description
Retort ring without boss head, closed, Ø 70 mm is a closed stainless-steel laboratory support ring sized for larger flasks and vessels on standard retort stands. The continuous closed ring offers uniform contact around a 70 mm diameter, improving stability for round-bottom flasks, evaporating dishes, or intermediate glassware during heating and reaction work. Without an integral boss head, the ring can be paired with a separate muff or clamp at any convenient height on the stand rod. Length is 200 mm, providing extended reach from the upright to the vessel centre. Made from stainless steel (Edelstahl), it delivers corrosion resistance and mechanical durability for everyday laboratory use. The article is supplied as a single piece with a net weight of 0,18 kg. This retort ring from manufacturer Witeg is suited to preparative chemistry, distillation setups, and teaching laboratories that need a robust closed ring without a fixed muff. Clear specifications (Ø 70 mm, length 200 mm) simplify matching to existing stand hardware and complementary rings of other diameters, supporting orderly multi-level assemblies on crowded benches.
This article is part of Clamps & bossheads, in Stands, clamps & racks.

Questions about Tripod ring without sleeve close Ø 70mm
What is this article?
Tripod ring without sleeve close Ø 70mm is the article on this page. Luminix Health distributes Witeg 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.
