Following the GL (glass laboratory) standard, the GL45 thread finish is a staple in laboratory glassware, recognized for its versatility and reliability across a wide range of applications. Found on glass bottles of various sizes—from small reagent containers to large solvent bottles—the GL45 thread is designed to ensure a secure, airtight seal, making it ideal for storing sensitive or volatile chemicals.

What sets the GL45 thread apart is its standardized design, which promotes compatibility across different manufacturers. This feature has made it a global favorite in laboratories, streamlining the interchangeability of caps, adapters, and accessories.
