Buchner Funnel vs. Hirsch Funnel: Know the Difference
By Shumaila Saeed || Published on January 20, 2024
A Buchner funnel is a flat-bottomed, porcelain funnel for vacuum filtration, while a Hirsch funnel is a smaller, conical-shaped funnel for filtering small quantities.
Key Differences
The Buchner funnel, typically made from porcelain or plastic, features a flat, perforated base suitable for filtering larger quantities. The Hirsch funnel, with its cone-shaped design and smaller size, is ideal for filtering smaller amounts of substance.
