The Stark interaction of polar molecules with an inhomogeneous electric field is exploited to select slow molecules from a room-temperature reservoir and guide them into an ultrahigh vacuum chamber. A linear electrostatic quadrupole with a curved section selects molecules with small transverse and longitudinal velocities. The source is tested with formaldehyde $({\mathrm{H}}_{2}\mathrm{CO})$ and deuterated ammonia $({\mathrm{ND}}_{3}).$ With ${\mathrm{H}}_{2}\mathrm{CO}$ a continuous flux is measured of $\ensuremath{\approx}{10}^{9}/\mathrm{s}$ and a longitudinal temperature of a few kelvin. The data are compared with the result of a Monte Carlo simulation.
