Buchner Funnel with Sintered Disc
Product Code : EL-F-10114
Lab Glassware Manufacturer manufactures, supplies and exports the Buchner Funnel with Sintered Disc from its production facility in Ambala, Haryana, with a fire-polished rim and stem, serving school and college laboratories, research institutes and industrial buyers across India and export markets that have recently included Armenia, Georgia and Azerbaijan — part of a wider base of enquiries from across the Caucasus.
Quick answer: This Buchner Funnel has a permanently fused sintered glass disc in place of loose filter paper, available in capacities from 35ml to 1000ml and in porosity grades 0 to 5 — graded from coarse to fine — aligned with the porosity classification set out in ISO 4793 for laboratory sintered (fritted) filters.

Choosing a Porosity Grade
Because the filter disc is permanently fused into the funnel body rather than a replaceable paper, the porosity grade has to be chosen up front to match the particle size being retained. Lab Glassware Manufacturer's porosity numbering follows the classification set out in ISO 4793 (Laboratory sintered (fritted) filters – Porosity grading, classification and designation), running from grade 0 (coarsest, for coarse precipitates and general filtration) to grade 5 (finest, for very fine precipitates). This is manufacturer-stated conformance, not a claim of third-party certification — buyers with a specific tender or accreditation requirement should confirm the exact grade and disc specification at enquiry stage before quotation. Because the disc cannot be swapped out, having the right grade on hand for each application avoids re-ordering.
Frequently Asked Questions
What porosity grades are available?
Grades 0 to 5, running from coarsest (grade 0) to finest (grade 5), following the porosity classification set out in ISO 4793 for sintered glass filters.
What capacities are available?
35ml, 80ml, 200ml, 500ml and 1000ml.
How is this different from a fritted-disc funnel with filter paper?
The sintered disc is permanently fused into the funnel body, so filtration does not depend on a separate filter paper — but the porosity grade must be selected up front since the disc cannot be swapped for a finer or coarser one afterward.
Do you export the Buchner Funnel with Sintered Disc outside India?
