An enclosed benchtop analytical device, as well as systems, processes, and techniques related thereto are disclosed. A benchtop analytical device can include an enclosure enclosing a probe and a sample. A compliance component can determine satisfaction of one or more compliance rules, such as a compliance rule relating to an enclosure being in an operable configuration based on a lid of the enclosure being closed.. If the compliance rule(s) is determined to be satisfied, the compliance component may enable the release of optical energy for interrogation of the sample via the probe. In some embodiments, the enclosure can enclose a sample plate that can be used to conveniently and accurately retain a sample in a suitable position within the enclosure.
