We report on a dual species laser cooling apparatus capable of collecting over ${10}^8$ ${}^{87}\mathrm{Rb}$ or ${}^{85}\mathrm{Rb}$ atoms from an atomic vapor or up to $(8\pm 2)\times {10}^7$ ${}^6\mathrm{Li}$ atoms directly into a magneto-optic trap (MOT) from an effusive oven without the need for a Zeeman slower. The use of a miniature atomic oven placed close to the trapping region yields a compact vacuum system with a captured flux of more than $4\times {10}^6$ lithium atoms per second and a high quality vacuum in the ${10}^{-10}\text{\hspace{0.17em} Torr}$ range. The atomic sources, laser system, and vacuum system are described. In addition, we use this system to study atom loss from the MOT due to interspecies collisions between ${}^6\mathrm{Li}$ and ${}^{85}\mathrm{Rb}$ or ${}^{87}\mathrm{Rb}$ . We report for the first time the heteronuclear loss coefficients for ${}^6\mathrm{Li}–{}^{85}\mathrm{Rb}$ mixtures.
