Quick answer: Buchner Funnels with an integrated glass sintered disc combine the funnel and filter into one reusable borosilicate unit, offering chemical inertness and reliable particulate retention for vacuum filtration without the need for separate filter paper. Buchner Funnels, Glass, With Sintered Disc is priced at approximately ₹325 (indicative market benchmark, incl. GST, August 2026).
These borosilicate Buchner funnels fuse a sintered disc directly into the funnel body, eliminating the need for separate filter paper while providing a chemically inert, reusable filtration surface. The glass construction allows the filtration process to be observed directly, which is useful for teaching purposes and for monitoring filtration progress during a procedure. They are well suited to routine vacuum filtration in college and research chemistry laboratories, including filtration involving corrosive chemicals within the limits of standard borosilicate resistance.

Frequently Asked Questions
Why does this funnel use a sintered disc instead of filter paper?
The fused sintered disc is reusable and chemically inert, avoiding the need for separate filter paper and reducing a potential source of contamination.
What is the disc porosity grade?
Exact porosity grade has not been independently verified for this listing — confirm the grade suited to your application with STEMAids before ordering.
Is this suitable for corrosive chemical filtration?
Borosilicate glass offers good general chemical resistance; for highly aggressive acids or alkalis, the porcelain version may be more suitable — confirm with STEMAids based on your specific reagents.
Is this reusable after cleaning?
Yes, sintered-disc Buchner funnels are generally designed for repeated use with proper cleaning between filtration runs.
Is this suitable for a college chemistry lab?
Yes — glass Buchner funnels with sintered discs are standard equipment for routine vacuum filtration in college and research laboratory settings.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
