We make use of a custom-designed cryo-CMOS multiplexer to enable multiple quantum devices to be characterized in a single cooldown of a dilution refrigerator. Combined with a packaging approach that integrates cryo-CMOS chips and a hot-swappable parallel-device test platform, we describe how this setup takes the standard wiring configuration of a dilution refrigerator as input and expands the capability for batch characterization of quantum devices at milli-Kelvin temperatures and high magnetic fields. The architecture of the cryo-CMOS multiplexer is discussed, and its performance is benchmarked using few-electron quantum dots and Hall mobility mapping measurements.
