The so-called "standard funnel" is the triangle funnel 60 degree angle. So 60 degree is designed to adapt to the angle that square or round filter paper folded once expanded into 60-degree angle into the inner wall of the funnel . This filter paper can relatively affixed to funnel, so the filter progress is sage and convenient. Standard funnel shape is similar with triangle funnel, except that the angle of the funnel is correct.
