Product Overview
The classic GL 25, GL 32, and GL 45 threaded screw caps for DURANĀ® laboratory bottles incorporate a proven cap plug sealing system that ensures a secure, liquid-tight seal, ideal for preventing leaks during storage or transport. These caps are available in four easily identifiable colours: blue, green, yellow, and grey. Matching pouring rings in the same colors are sold separately, allowing for complete colour coordination. This colour-coding system simplifies the identification of different media types in the lab and significantly reduces the risk of cross-contamination or mix-ups when interchanging screw caps.
