Kartell Buchner Funnels

Robust and lightweight, Kartell Buchner Funnels are designed for ease of use in the Buchner Filtration process.

The Buchner Filtration process uses a Buchner Flask connected to a vacuum pump to improve the filtration process. The cylinder on top is designed to hold extra material and is separated from the funnel by a perforated plate. The advantage of this system is that more material can be filtered, and the process is said to be faster than the traditional method of allowing the solvent to be filtered using the force of gravity.

The funnels feature two-piece polypropylene construction. The base of the top section is perforated to allow solvent to pass through and can be used in conjunction with both the Kartell discs for Buchner Funnels and filter paper to filter the solvent while trapping the original material. With a weave of 250 µ, the optional discs are an extra method of avoiding clogging the filter holes in the funnel.

The polypropylene used in the funnels is heat- and corrosion-resistant, and features good chemical resistance. The top and bottom sections can be separated for easy and total cleaning, and can be sterilised by autoclaving.

The funnels are available in eight sizes: from Art. 437, which has a filter diameter of 42.5 mm and a capacity of 40 mL, up to Art. 445, which has a 240 mm filter diameter and a capacity of 6000 mL.
