The last stop on our tour is the Observation Room. No special clothing is required for entry into the observation room because no samples are kept here. This room has windows which allow occupants to view the Pristine Sample Laboratory, the Clean Change Room, and the Transfer Room. An airlock between the Observation Room and the Pristine Lab is used for transferring samples, tools, containers, and documents into and out of the laboratory. This area is also used for reviewing documents to verify that sample allocations comply with investigators' requests before they are actually shipped.

The Observation Room also houses readouts which display the alarm status for the oxygen and water contents of the cabinets as well as the oxygen levels in the air in the various areas of the facility.
