A glass-cell apparatus and a dc magnetic trap with radial gradient of and axial curvature of were used to capture and evaporatively cool rubidium 87 atoms. Below a critical temperature of , Bose-Einstein condensation was observed with 106 atoms in the trap. Pure condensates with more than 105 atoms and peak densities exceeding were produced.
