Porcelain funnel

Introduction to Porcelain Funnels

Porcelain funnels are specialized laboratory filtration tools, typically designed as perforated flat-bottom Buechner funnels to facilitate the separation of precipitates or solids from liquids under reduced pressure. This labware is widely used in chemical analysis, organic synthesis, and test sample preparation thanks to its mechanical strength and excellent chemical resistance.

When selecting a porcelain funnel, users should clearly determine the working volume and filter plate diameter to ensure compatibility with the membrane filter or filter paper size in the experiment. At Hoa Viet, customers can select Jipo porcelain Buchner funnels originating from the Czech Republic with a capacity of 35ml, using filter membranes with a diameter of 45mm. If interested, please contact Hoa Viet for technical support and to request a quote.

What equipment and accessories are Buechner porcelain funnels typically used with?

Buechner porcelain funnels are typically fitted onto vacuum filter flasks using a rubber adapter or gasket, connected to a vacuum pump. During operation, a filter paper or flat membrane filter must be placed to completely cover the perforated plate inside the funnel.

Which brand's porcelain funnels does Hoa Viet currently distribute?

Currently, Hoa Viet distributes Buechner porcelain funnels from Jipo, manufactured in the Czech Republic.

How to select the correct filter membrane size for a porcelain funnel?

The diameter of the filter membrane or filter paper must fit closely to completely cover the perforations at the bottom of the funnel without being too large to cause edge curling. For example, for a 35ml Jipo Buechner porcelain funnel, the suitable filter membrane size is 45mm in diameter.
