Laboratory equipment arrives in random sizes, with each piece having its own unique set of utilities, e.g. electrical power, cooling water, airflow, computer hook-up cables, etc. All of these are delivered through sealed pass-throughs. Enclosures can also be mounted to rigid door frames for access. Room lighting provides visibility. Internal temperatures can be tolerated up to 180F continuous and 200F transient.
