Description
Cork rings provide a stable base for round-bottom flasks and similar spherical laboratory glassware during routine bench work. Fabricated from cork, they offer a soft, non-slip surface that reduces the risk of rolling or impact damage while flasks are filled, emptied, cooled or held between operations. These rings belong to the group of miscellaneous laboratory materials and are commonly placed under distillation, reaction or receiving flasks whenever a secure temporary stand is required. The natural cork material is lightweight, easy to position and free from hard edges that could scratch glass. Available as a single piece from manufacturer Hecht, the rings integrate smoothly into standard laboratory glassware handling and organisation. They support everyday workflows in analytical, preparative and teaching laboratories where simple, reliable flask supports help maintain order and protect valuable vessels on the work surface.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cork rings for flasks
What is this article?
Cork rings for flasks is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
