We simultaneously measure the gravitationally induced phase shift in two Raman-type matter-wave interferometers operated with laser-cooled ensembles of Rb-87 and K-39 atoms. Our measurement yields an Eotvos ratio of eta(Rb,K) = (0.3 +/- 5.4) x 10(-7). We briefly estimate possible bias effects and present strategies for future improvements.
