The tapered natural-rubber profile supports secure closure of flasks, tubes and similar openings commonly encountered in wet-chemistry and general laboratory practice. Supplied in a pack of 25 pc(s) with a total weight of 0,126 kg, the stoppers are ready for stockrooms and multi-user benches. They fall within labware categories covering laboratory glass, vessels, consumables, stoppers and clamps, underscoring their role as everyday sealing accessories. These Rotilabo® natural-rubber stoppers from manufacturer ROTH SELECTION provide a flexible fit for standard neck sizes matching the stated diameters and height. Typical uses include temporary or intermediate sealing during sample storage, reaction setups and transport of aqueous solutions where a resilient rubber plug is appropriate.
