Place where scientific research and development is conducted and analyses performed, in contrast with the field or factory. Most laboratories are characterized by controlled uniformity of conditions (constant temperature, humidity, cleanliness). Modern laboratories use a vast number of instruments and procedures to study, systematize, or quantify the objects of their attention. Procedures often include sampling, pretreatment and treatment, measurement, calculation, and presentation of results; each may be carried out by techniques ranging from having an unaided person use crude tools to running an automated analysis system with computer controls, data storage, and elaborate readouts.

Laboratories exist at the nexus of commerce, academic disciplines, and the State in early twenty-first-century America. Laboratories have been, and remain, a source of American military and economic power; their products indispensable elements for everyday life. How these organizations, ostensibly dedicated to the production of new knowledge and technologies, came to occupy such a central place in the landscape of American history is at one with the history of American science and technology as well as the growth of the American state during the twentieth century.

The Nineteenth Century

Although laboratories existed to test materials for railroads and small chemical concerns, as well as in some of the nation's colleges and universities such as Harvard and the Lawrence Scientific School at Yale, laboratories that we might recognize as such date from two distinct events—the 1862 Morrill Land Grant Act and the establishment of the Johns Hopkins University in 1876. The Land Grant Act provided each state in the Union with funds to establish an institution of higher learning with an emphasis on practical knowledge. Hopkins followed the German model of higher education, with its reverence for research, albeit with substantial local modification. Uniting these two temporally distinct events was a common recognition that laboratories are sites where the producers and consumers of technical knowledge bargain over a host of meanings.

Prior to World War II (1939–1945), the federal government supported research that might serve to aid in the development of the nation's natural resources. Hence, agriculture was a major beneficiary of Department of Agriculture funding through the experiment station at each state's land grant institution. Successful researchers enrolled local farmers to support research and teaching that might aid the local agricultural economy. Distinctive and important results emerged from these local constellations, ranging from the famous Babcock butterfat test to the development of hybrid corn. Balancing local needs with their own agendas, land grant researchers enacted the American laboratory's dilemma—those charged with the production of knowledge were often the least powerful actors in any given locale.

The founding of the Johns Hopkins University is central for understanding the laboratory's history in America. Until the 1980s, historians viewed the establishment of this new institution in Baltimore as simply an attempt to bring the German model of research to American soil and break with the traditional American college, with its emphasis on the production of morally solid citizens. Under Daniel Coit Gilman's leadership, the new university hired professors trained in European universities, including Henry Rowland (physics), Ira Remsen (chemistry), Henry Newell Martin (biology) and J. J. Sylvester (mathematics). However, far from abandoning the college's traditional function, the new institution's laboratories and seminar rooms became new sites for the production of both knowledge and upstanding citizens, the majority of which became college teachers. Hopkins valued research, but it was inseparable from teaching. As Gilman once explained, "in the hunt for truth we are first men and then hunters"; the antebellum college's moral economy moved to the new university. So great was the connection between research and teaching that Remsen expressed dismay when Gilman left Hopkins to become the first president of the Carnegie Institution of Washington (CIW), a private research institution.

Research and No Teaching

Separating research from teaching was among the great social accomplishments of the twentieth century. Private philanthropy and the emergence of the corporate laboratory were crucial in achieving this division. Around 1900, General Electric (GE) and AT&T established the first industrial research laboratories in America. Rather than produce students and theses, these laboratories produced new technologies and patents, the new corporate currency. For example, after many failures, Willis Whitney's group at GE invented the ductile tungsten filament for light bulbs, creating an array of patents that made GE untouchable in this growing market. At AT&T, researchers patented various important aspects of radio so as to maintain the system's monopoly on long distance communication. Far from being a university in exile, the corporate laboratory invented the firm's future and protected its investments. Industrial research was always basic to corporate needs, but that did not mean such work was mundane or less intellectually sophisticated than university based research. GE's Irving Langmuir won his 1932 Nobel Prize in Chemistry for his explanation of a basic GE problem: why did light bulbs darken over time?

The establishment of the Rockefeller Institute for Medical Research (now Rockefeller University) and the CIW were also salient in separating research from teaching. Both were the products of the massive fortunes earned by the nineteenth century's great robber barons, but each had different ends. Rockefeller's Institute, founded in 1901, had as its mission the understanding and treatment of disease and the separation of biomedical research from the education of physicians. Sinclair Lewis's Arrowsmith offers a fine depiction of Institute life. The CIW, founded in 1902 with $10 million in U.S. Steel bonds, sought to find the "exceptional man" and free him from the distractions of everyday life with financial support. Finding the exceptional man proved difficult, and the CIW settled for the creation of an array of departments under the leadership of recognized leaders in the natural and social sciences as well as the humanities. Only the natural science departments survived into the twenty-first century. Cleaving research from teaching allowed the laboratory to become portable and capable of existing in a variety of contexts.

War and the State

The two world wars facilitated the growth of U.S. laboratories in ways that had been heretofore unthinkable. World War I (1914–1918) provided American science with a new institution, the National Research Council (NRC) of the National Academy of Sciences, which served as the agent for the Rockefeller Foundation's massive postdoctoral fellowship program, which provided American researchers with funds to study at elite institutions in the United States and Europe. These young researchers returned to take up faculty positions, establish laboratories, and effectively end America's reliance on Europe as a source of advanced training in the sciences. The 1920s also featured what one observer called a "fever of commercialized science," as laboratories spread throughout American industry. Although the Great Depression slowed the spread of industrial laboratories, the crisis also acted as a selection mechanism, allowing only those laboratories with independent sources of revenue or outstanding research to survive.

World War II and the massive mobilization of American science led by CIW President Vannevar Bush effectively made the nation's laboratories at one with the nation's security and prosperity. With the federal government's support, the Manhattan Project, the American atomic bomb project, created a whole set of laboratories—including Los Alamos, Oak Ridge, and the Metallurgical Laboratory. Equally important were the laboratories established to develop radar (the MIT Radiation Laboratory), the proximity fuze (The Johns Hopkins University Applied Physics Laboratory), and guided missiles (CalTech's Jet Propulsion Laboratory). Government, but more specifically military patronage, heretofore unacceptable to the nation's scientific elite, propelled the laboratory into its central role in American life. Contrary to what many originally believed, American researchers found military problems a rich source of intellectually and technologically important questions. Even more importantly, there was someone eager to pay for answers—the armed services. Bush's famous 1945 report, Science—The Endless Frontier, and the visible demonstration of scientific power made at Hiroshima and Nagasaki, made the nation's laboratories and their products essential for America's coming struggle with the Soviet Union as well as the country's future economic growth.

During the Cold War, military patronage supported the largest expansion of the nation's research capabilities in both university and corporate laboratories. Four basic projects dominated the nation's laboratories: the development of the ballistic missile; the various attempts to design and build adequate continental defense systems; the introduction of quantitative methods into the social sciences; and the development of new technologies of surveillance and interpretation for the purposes of intelligence gathering. One basic technology emerging from this quartet was the networked digital computer, a tool now indispensable in so many contexts, including the modern research laboratory. In the biomedical disciplines, the National Institutes of Health (NIH) supported a similar and equally expensive expansion that had as its visible endeavor the human genome project.

In 1990, one-sixth of the nation's scientists and engineers were employed in more than 700 federally funded laboratories, including sixty-five Department of Defense and Department of Energy institutions, having annual budgets ranging from $15 billion to $21 billion, depending on who and what is counted. Even with the Cold War's end and the lessening of federal funds, the nation's laboratories flourished as government and industry rushed to continue the vital business of innovation.

The Present and the Future

As of 2000, industry outspent the federal government as the laboratory's greatest patron, but much of that work involved the laborious and difficult process of developing ideas into viable commercial products. University laboratories still account for the majority of basic research done in the United States. Although the events of 11 September 2001 will undoubtedly affect federal funding of research and lead to an increase in military research, the major areas in which laboratories will play a role will remain roughly as they were in 2000: biotechnology, including the massive private investment by the pharmaceutical industry as well as the ongoing attempts to harvest the work of the human genome project; nanotechnology, the attempt to develop sophisticated miniature technologies to act in a variety of contexts, including the human body and the battlefield; and information technology, as researchers attempt to make computers ubiquitous, easy to use, and capable of mining the vast data archives created by government and industry. In the first and last of these domains, corporate laboratories will play vital roles as individual firms attempt to bring new therapies and new technologies to market. Nanotechnology will remain a ward of the state as researchers attempt to develop means of manipulating their newfound Lilliputian world effectively. If successful, corporations will adopt that research just as they adopted the biotechnology research originally done in NIH-funded laboratories. The twenty-first century, like the twentieth, will be the laboratory's century.

Michael Faraday, 19th century physicist and chemist, in his lab.

A laboratory (informally, lab) is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. The title of laboratory is also used for certain other facilities where the processes or equipment used are similar to those in scientific laboratories. These notably include:

In recent years government and private centers for innovation in learning, leadership and organization have adopted "lab" in their name to emphasize the experimental and research-oriented nature of their work.

Scientific laboratories can be found in schools and universities, in industry, in government or military facilities, and even aboard ships and spacecraft. A laboratory might offer work space for just one to more than thirty researchers depending on its size and purpose.

Characteristics of scientific laboratories

Labs used for scientific research take many forms because of the differing requirements of specialists in the various fields of science. A physics lab might contain a particle accelerator or vacuum chamber, while a metallurgy lab could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's lab might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data collected elsewhere. Scientists in other fields will use still other types of laboratories. Despite the great differences among laboratories, some features are common. The use of workbenches or countertops at which the scientist may choose to either sit or stand is a common way to ensure comfortable working conditions for the researcher, who may spend a large portion of his or her working day in the laboratory. The provision of cabinets for the storage of laboratory equipment is quite common. It is traditional for a scientist to record an experiment's progress in a laboratory notebook, but modern labs almost always contain at least one computer workstation for data collection and analysis.

Lab safety

In some laboratories, the conditions are no more dangerous than in any other room. In many labs, though, hazards are present. Laboratory hazards are as varied as the subjects of study in laboratories, and might include poisons; infectious agents; flammable, explosive, or radioactive materials; moving machinery; extreme temperatures; strong magnetic fields or high voltage. In laboratories where dangerous conditions might exist, safety precautions are important. Rules exist to minimize the individual's risk, and safety equipment is used to protect the lab user from injury or to assist in responding to an emergency.

The Occupational Safety and Health Administration (OSHA) in the United States, recognizing the unique characteristics of the laboratory workplace, has tailored a standard for occupational exposure to hazardous chemicals in laboratories. This standard is often referred to as the "Laboratory Standard". Under this standard, a laboratory is required to produce a Chemical Hygiene Plan (CHP) which addresses the specific hazards found in its location, and its approach to them.

In determining the proper Chemical Hygiene Plan for a particular business or laboratory, it is necessary to understand the requirements of the standard, evaluation of your current safety, health and environmental practices and assessment of your hazards. The CHP must be reviewed annually. Many schools and businesses employ safety, health and environmental specialists, such as Chemical Hygiene OFficer (CHO) to develop, manage and evaluation their CHP. Additionally, third party review is also used to provide an objective "outside view" which provides a fresh look at areas and problems that may be taken for granted or overlooked due to habit.

Inspections and audits should also be conducted on a regular basis to assess hazards due to chemical handling and storage, electrical equipment, biohazards, hazardous waste management, housekeeping and emergency preparedness, radiation safety, ventilation as well as respiratory testing and indoor air quality. An important element of such audits is the review of regulatory compliance and the training of individuals who have access to and/or work in the laboratory. Training is critical to the ongoing safe operation of the laboratory facility. Educators, staff and management must be engaged in working to reduce the likelihood of accidents, injuries and potential litigation.
