Description
Polypropylene stoppers provide a reusable, cost-effective alternative to glass or rubber options for sealing laboratory glassware. Designed for standard ground joint sizes (19/26, 24/29, 29/32), they offer a snug and secure fit in flasks, condensers, and adapters.
Ideal for use in chemical handling, distillation setups, and general lab sealing applications, their robust construction resists deformation under thermal and chemical stress. These stoppers are non-reactive and easy to clean, making them suitable for repeated use across educational, industrial, and research laboratories.
A practical choice for modern labs, these polypropylene stoppers ensure leak-resistant, durable performance without compromising compatibility or reliability.
