WebGraham also performed equal countercurrent experiments in 1863, using a long closed-tube apparatus he devised. This sort of apparatus is now usually called a Loschmidt diffusion tube after Loschmidt, who used a modified version of the tube in 1870 to make a series of accurate diffusion measurements on a number of gas pairs.
