    What People Are Saying

    Inexpensive option versus porcelain
  • Neil

  • This is a cheaper version than the porcelain Buchner funnel. The advantages are price and it won't break if you drop it. The disadvantage is that the bed isn't exactly flat. This isn't a problem for some users but it will be for others. It is a 2-piece design so I suspect that age will affect it from warping over time or use with solvents or heat.

      Buchner funnel, 90 mm diameter, poly

      A Buchner funnel is used for vacuum filtration. This two-part polypropylene plastic funnel is 90 mm in diameter and has a capacity of about 300 ml. The filter has hundreds of small perforations for better filtration efficiency. The stem tapers from about 13 mm OD at the end to 18 mm OD at the cone - much smaller than typical porcelain Buchner funnels.

      Polypropylene is lightweight, acid and alkali resistant, easy to clean, and autoclavable. The top portion snaps to the lower one, forming a vacuum-tight seal that does not have to be greased.

      This Buchner funnel can be used with a vacuum filtration flask and a rubber stopper of the correct size to fit the flask (not included). Be sure to order with 9 cm filter paper.
