Description
Retort ring, 18/10 steel, ID 70 mm is a classic laboratory support ring for mounting glassware on retort stands in heating, reflux and distillation setups. Made from 18/10 stainless steel, it delivers a robust, corrosion-resistant ring with an inner diameter of 70 mm suitable for many standard flasks and funnels. The shaft length of 200 mm provides generous reach for positioning the ring at the required height on a stand rod when used with a separate boss head or clamp. Weighing 174,0 g, the component remains practical to handle while offering stable support under typical laboratory loads. This retort ring from manufacturer Bochem is intended for chemistry laboratories, teaching environments and preparative work where dependable metal ring supports are needed. Stainless steel construction ensures longevity under routine bench conditions. Supplied individually, the ring pairs with conventional stand hardware to hold round-bottom vessels, evaporating dishes or funnels securely during experimental procedures that involve heating or continuous liquid handling.

Questions about Retort ring 18/10 steel, ID=70mm
What is this article?
Retort ring 18/10 steel, ID=70mm is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Stands, rods & bases, inside Stands, clamps & racks, in Matériel de laboratoire.
A retort stand is a base and a rod. The base mass keeps a clamped flask from tipping. Rod diameter decides which bossheads fit. A light base under a heavy condenser is how glassware falls.
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.
