We describe an atom trap for Bose-Einstein condensates of 87Rb to be used in atom interferometry experiments. The trap is based on a time-orbiting potential waveguide. It supports the atoms against gravity while providing weak confinement to minimize interaction effects. We observe harmonic oscillation frequencies (\ensuremathωx,\ensuremathωy,\ensuremathωz) as low as 2\ensuremathπ\ifmmode×\else\texttimes\fi(6.0,1.2,3.3)\phantom\rule0.3em0exHz. Up to 2\ifmmode×\else\texttimes\fi104 condensate atoms have been loaded into the trap, at estimated temperatures as low as 850\phantom\rule0.3em0expK. We anticipate that interferometer measurement times of 1\phantom\rule0.3em0exs or more should be achievable in this device.
