Buchner Funnels, Porcelain, With Sintered Disc
Vitreous Ceramic Composition: Constructed from high-purity, glazed porcelain that provides exceptional resistance to thermal shock and corrosive reagents, including concentrated acids and alkalis, without compromising structural integrity.
Permeability-Optimized Sintered Plate: Features a fused-in ceramic disc with controlled porosity, ensuring precise particulate retention and uniform flow rates while facilitating easy cleaning and sterilization for repeated industrial use.
₹470.00
Quick answer: Porcelain Buchner Funnels with an integrated sintered disc combine the funnel and filter into a reusable ceramic unit, offering strong chemical and thermal resistance for vacuum filtration involving aggressive acids or alkalis in chemistry laboratories. Buchner Funnels, Porcelain, With Sintered Disc is priced at approximately ₹470 (indicative market benchmark, incl. GST, August 2026).
These porcelain Buchner funnels fuse a sintered disc directly into a high-density ceramic body, removing the need for separate filter paper while providing strong resistance to both chemical attack and high temperatures. This makes them well suited to vacuum filtration involving aggressive acids or alkalis, or filtration steps that follow a heating stage, where a standard glass funnel might be more vulnerable to thermal or chemical stress. Porcelain construction is a practical choice for college and research chemistry laboratories running filtration procedures with harsher reagents than typical routine work requires.

Frequently Asked Questions
Why choose porcelain over glass for a Buchner funnel?
Porcelain offers stronger chemical and thermal resistance than glass, making it better suited to filtration involving aggressive acids, alkalis, or high-temperature applications.
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 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 — porcelain Buchner funnels are standard equipment for filtration work involving harsher reagents in college and research laboratory settings.
What is the difference between this and the glass version?
The porcelain version offers greater chemical and thermal resistance, while the glass version allows visual monitoring of the filtration process; choose based on your specific application’s needs.
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.
