By integrating a permanently sealed glass fritted disc directly into the structural base of the funnel body, this hardware completely eliminates the need for separate paper filters or removable support screens. This design prevents filter paper blowouts and bypass leaks, ensuring maximum sample recovery and quantitative accuracy during fine precipitate collection, recrystallization protocols, and general solvent purifications.
Key Functional Benefits:
- Integrated Glass Fritted Disc: The built-in porous matrix serves as an unyielding structural platform for particulate retention, eliminating paper filter costs, sample scraping losses, and chemical interactions.
- Heavy-Duty Beaded Rim: Re-engineered with a reinforced beaded rim that increases structural resistance against mechanical chipping and impacts during routine cleanings and storage setup.
- Superior Thermal and Chemical Stamina: Premium borosilicate glass composition withstands autoclave sterilization cycles and high-vacuum pressures without cracking or structural failure.
- Targeted Porosity Selection: Available in Fine, Medium, or Coarse porosities to perfectly match your target precipitate sizes and fluid flow requirements.
