1. A sampling device for surface sampling, the sampling device comprising:
a sampling head supporting and coupled with a sampling medium configured for surface sampling, wherein the sampling medium is attached to a distal portion of the sampling head;
an actuator releasably coupled with the sampling head, wherein the actuator has a power source and is configured such that powered operation of the actuator imparts powered movement of the sampling head, thereby moving the sampling medium when attached to the sampling head during sampling; and
a sample container releasably attached to the sampling head so as to contain the sampling medium therein while attached to the sampling head, wherein the sampling head includes a proximal coupling that sealingly interfaces with a top opening of the sample container to contain the sampling medium while attached to the sampling head.
