A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
The USP Controlled Room Temperature is a series of United States Pharmacopeia guidelines for the storage of pharmaceuticals; [1] the relevant omnibus standard is USP 797. [2] [3] Although 100% compliance remains challenging for any given facility, [4] the larger protocol may be regarded as constituting a form of clean room [5] which is included in a suite of best practices.
Depending on the cleanliness requirements of the controlled space, more fan filter units can be added to the grid in order to meet ISO standards for airflow velocity and air changes per hour. [ 4 ] FFUs can be used in place of a more conventional recirculating air unit such as a ducted or plenum air system.
The centre's Class 100,000 clean rooms cover an area of around 3,800 m 2 (41,000 sq ft). [4] It is capable of the assembly, integration and testing of several satellites of type low Earth orbit (LEO) and geosynchronous orbit (GEO) with a mass up to five tonnes simultaneously. [ 11 ]
The forceful "cleansing" of surfaces before entering clean environments reduces the number of airborne particulates introduced. [1] [2] When properly incorporated into cleanroom design, air showers provide an ISO-classified transition vestibule to ensure the cleanliness of the classified cleanroom.
The facilities include supersonic, hypersonic and subsonic wind-tunnels, a high-sensitivity navigation simulator, a structures and materials testing laboratory, and an ISO 8, class 100,000 clean room for the development of micro satellites.
Barrier and Isolator designs are used throughout the industries, from sterile injectable drug filling to cytotoxic sterile drug compounding to electronics manufacturing to orange juice filling. Pharmaceutical industry and pharmacy compounding isolators are used for maintaining sterility of a drug, and that is the focus of this article.
The new science center officially opened for the Fall 2013 semester. It has expanded labs for all science majors other than computer science, [12] and includes a new class 100000 clean room facility for the rapidly expanded Nanotechnology program, allowing the university to rely less on Penn State's clean rooms.
