Description
Flask tongs 230 mm with cork are laboratory tools intended for the secure gripping and transfer of flasks in everyday experimental practice. With an overall length of 230 mm they provide comfortable reach while distancing the user’s hands from heated glassware, burners, and hot plates. Cork-lined jaws cushion the vessel surface, help limit scratching, and increase friction for a steadier hold on round or tapered flask bodies. The tongs are appropriate for general chemistry, analytical, and teaching laboratories where round-bottom, Erlenmeyer, or similar flasks must be lifted, repositioned, or moved short distances without direct hand contact. Typical uses include removing a flask from a heating source, placing vessels for reaction work-up, and supporting safe handling during filtration or sample preparation. Delivered as 1 pc, the instrument fits standard laboratory glassware-handling sets. From manufacturer RSG, these flask tongs belong to the group of other laboratory instruments used with flasks and related vessels. Their straightforward construction makes them a practical accessory for routine workflows that demand controlled, repeatable manipulation of laboratory flasks.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Beaker tong, cork lined, 230mm
What is this article?
Beaker tong, cork lined, 230mm is the article on this page. Luminix Health distributes RSG for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
