Buchner Funnel 500 Milliliters – Medium Frit (G2) Lab Glassware with 24/40 Joint Made of Borosilicate

The 500 milliliters Buchner Funnel Medium Frit G2 is a borosilicate glass filtration component designed for compatible vacuum-filtration assemblies. Published specifications include a 500 milliliters nominal capacity, approximately 94 mm inner diameter, 100 mm depth, G2 medium frit, and standard 24/40 ground-glass joint.

The integrated frit in the 500 milliliters Buchner Funnel Medium Frit G2 is listed at approximately 40–80 microns. A fritted design provides a fixed porous filtration surface and can be used for procedures where its pore range is appropriate. Actual retention and flow depend on particle size, liquid viscosity, solids loading, vacuum level, temperature, and the condition of the frit.

Borosilicate construction gives the 500 milliliters Buchner Funnel Medium Frit G2 useful thermal properties and resistance to many chemicals. The 24/40 joint should be matched only with compatible glassware. Verify chemical compatibility for the material being filtered and avoid rapid temperature changes or mechanical stress that could damage laboratory glass.

Inspect the funnel, frit, ground joint, and vacuum connection before every use. Do not place chipped, cracked, deeply scratched, or otherwise damaged glassware under vacuum. Use a vacuum-rated receiving flask and support the assembly appropriately. Fritted surfaces should be cleaned using procedures compatible with both the glass and the material retained in the frit; avoid forcing debris deeper into the porous disc.
