Buchner Frit Funnel with fritted disc mouth is a durable filtration instrument made of high-grade borosilicate glass. It is specifically designed for vacuum filtration because it has a built-in porous fritted glass disc that captures particles without using filter paper. This ensures smooth and uninterrupted flow of liquid while saving time.

This Buchner funnel is suitable for fine and coarse filtration works in busy laboratories. It is available with Porosity Grades 3 and 4 in 30ml, 70ml, 125ml, 250ml, and 500ml sizes.

Features Of Buchner Funnel And Vacuum Filtration

● Built-in fritted disc: Saves resources and increases efficiency because no separate filter paper is needed.

● Durable borosilicate glass(Boro 3.3): Exceptional thermal resistance and durability to chemicals.

● Wide range of capacity: Filtrations at micro-scale tasks and larger volumes are within reach.

● Stable porosity: Consistent filtering and flow rates due to reliable performance.

● Ideal for vacuum systems: Standard design for vacuum filtration makes it compatible with accessories.

● Reusable and autoclavable: Endures repeated sterilization without losing performance.

Frequently Asked Questions (FAQ)

Q1: What are Buchner funnels used for?

A: Buchner funnels are filtration devices for separating solids from liquids. The fritted disc version of the Filter Funnel (Buchner Funnel) offers self-filtering capabilities that increase its efficiency in retaining particles.

Q2: How do Buchner funnels and vacuum filtration systems work together?

A: In vacuum filtration, a Buchner funnel is placed over a filtering flask that is connected to a vacuum pump. The pressure difference caused by the pump draws the liquid through the fritted disc while leaving solids behind, which is commonplace in chemistry and pathology labs.

Q3: Is it possible to reuse a filter funnel (Buchner funnel) with fritted disc?

A: Yes. This funnel is comprised of durable borosilicate glass which allows for multiple sterilizations without structurally compromising the funnel or filter efficiency.
