1.0 SCOPE, OBJECTIVE, CLASSIFICATION, INNOVATIVE DESIGN, DEFINITIONS

1.1 Scope This performance and hardware specification covers a negative pressure glove box designed with all the airflow discharged to the building exhaust system. The glove box shall be designed with multiple hinged sashes and two chambers, the side load chamber and work zone. Integral with the glove box is a high efficiency particulate air filtration system designed with efficiency such that sterile air is produced in the work zone and simultaneously the work zone air is filtered and discharged to a building exhaust system. The use of toxic chemicals associated with pharmaceutical applications is permitted.

1.2 Objective The objective of this document is to provide University specifications for the procurement of negative pressure glove box glove boxes designed with a negative pressure plenum, which is contiguous to the ambient environment via a sealed metal barrier.

1.2.1 Noncompliance Glove boxes which have been selected from the competitive bidding process and delivered

to the University shall conform to the specifications and standards cited in this document. In the event that the delivered glove box does not conform to these requirements, the manufacturer shall be contacted by the University Agent to arrange for rectification of any identified non-compliance problem either in performance and/or construction specification. If the non-compliance problem cannot be resolved in 10 working days following receipt of notice, it will be the responsibility of the supplier to bear expense to re-crate and remove the equipment from the University property within the following 10 working day period. Unless prior arrangements are made, at the end of the second 10-day period the University, at its option, may have a commercial moving and storage agency remove the equipment from the campus and store the glove box at the manufacturer's expense.
