  We present a new quantum gas apparatus for ultracold mixtures of K and Cs
atoms and ultracold samples of KCs ground-state molecules. We demonstrate the
apparatus' capabilities by producing Bose-Einstein condensates (BEC) of 39K and
133Cs in a manner that will eventually allow sequential condensation within one
experimental cycle, precise sample overlap, and magnetic association of atoms
into KCs molecules. The condensates are created independently without relying
on sympathetic cooling. Our approach is universal and applicable to other
species combinations when the two species show dramatically different behavior
in terms of loss mechanisms and post laser cooling temperatures, i.e. species
combinations that make parallel generation of quantum degenerate samples
challenging. We give an outlook over the next experiments involving e.g. sample
mixing, molecule formation, and transport into a science chamber for
high-resolution spatial imaging of novel quantum-many body phases based on
K-Cs.
