Sintered Discs
Sintered discs are porous glass filters made by fusing fine glass particles into a rigid, disk-shaped structure. They are commonly used in laboratory filtration setups for retaining solids while allowing liquids or gases to pass through. Resistant to chemical corrosion and thermal shock, they are ideal for use in funnels, gas dispersion tubes, and filter assemblies.
Specifications
- Material: Manufactured from chemically resistant borosilicate glass.
- Porosity Grades: Available in grades 0 to 5, covering a wide range of pore sizes (from coarse to fine).
- Application: Used in filtration, gas dispersion, and support for catalysts or reagents in lab apparatus.
- Design: Rigid, non-flexible disc shape suitable for integration into glassware or apparatus joints.
