摘要： A sampling device useful for determining whether microorganisms are present on a given surface includes a lid member and a base member. The lid member includes a flange that provides visual and tactile indications to a technician of the position of their fingers relative to an edge of the lid member. This increases the ability to avoid accidental or inadvertent contact with a sampling media. The flange is provided with a plurality of lugs that operate to maintain some spacing between the flange and a corresponding base member. This spacing is especially advantageous in situations where air flow is desirable within the sampling device. The base member includes a first cavity for supporting a sampling media and a second cavity. The second cavity includes a plurality of ribs that are contoured to securely fit a lid member partially within the second cavity so that a plurality of sampling devices can be stacked in a convenient and reliable fashion.
