Abstract: The invention provides exemplary systems and methods for releasably securing a data storage device within a data storage system. In one exemplary embodiment, the invention comprises a cabinet which defines an enclosure. The data storage device is removably held within the enclosure. A cover is further provided which comprises a pivot end and a latch end. The pivot end is pivotally attached to the data storage device so that pivoting of the cover will release the data storage device at least partially from the enclosure. A cover latch is operably attached to the latch end, with the cover latch engaging the data storage device to prevent pivoting of the cover when the cover is closed.

Abstract: The invention provides exemplary testing devices, systems, and methods for evaluating the permeation of various chemicals through different types of cells. In one exemplary embodiment, a testing device is provided which comprises a plate defining at least one well having an open top end. At least one membrane is insertable into the well in a generally vertical orientation to divide the well into separate chambers. The membrane is removable from the well to allow the cells to be grown on the membrane before insertion into the well.
