Abstract: A specimen plate having a lengthwise slidable cover is placed on a carriage to move therewith into and out of an isolation chamber. A cover holder, movable in and out both relative to the carriage and with it, detachably retains the cover and prevents it from moving with the carriage beyond predetermined limits, so that the specimen plate is slid out of the cover and exposed while moving into the isolation chamber with the carriage, and is slid back into the cover as it is moved out of the isolation chamber.
