Iron rings used in a laboratory. An iron ring or ring clamp is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. [1] In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder. [2]
In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both usually made of metal.
The Iron Ring is made from either iron or stainless steel. [9] It is intended to be worn on the little finger of the working (dominant) hand. [ 9 ] There, the facets act as a sharp reminder of one's obligation while the engineer works, because it could drag on the writing surface while the engineer is drawing or writing. [ 8 ]
A utility clamp is a laboratory apparatus resembling a pair of scissors.The screw in the middle works as the wide adjustment of 2-prong. [1] It is composed of 3 parts: 2-prong adjust, metal rod, and clamp down (the clamp is attached to the ring stand for adjusting the height).

A separate study showed that fish-oil derived omega-3s may improve muscle mass, strength, and physical function in older adults with stable weight, and HMB improved both muscle mass and strength ...
Heme (American English), or haem (Commonwealth English, both pronounced /hi:m/ HEEM), is a ring-shaped iron-containing molecular component of hemoglobin, which is necessary to bind oxygen in the bloodstream. It is composed of four pyrrole rings with 2 vinyl and 2 propionic acid side chains. [1] Heme is biosynthesized in both the bone marrow and ...
The triangle is usually supported on a tripod or iron ring. Unlike wire gauze, which primarily supports glassware such as beakers, flasks, or evaporating dishes and provides indirect heat transfer to the glassware, the pipeclay triangle normally supports a crucible and allows the flame to heat the crucible directly. The triangular shape allows ...
