laboratory 30秒で
- A laboratory is a specialized, controlled environment designed for scientific research, experimentation, and the precise analysis of substances using technical equipment and rigorous protocols.
- Commonly abbreviated as 'lab,' these facilities are essential in fields such as medicine, chemistry, and forensics to verify facts and develop new technologies safely.
- Whether in a school or a multi-billion dollar corporation, a laboratory emphasizes safety, cleanliness, and the systematic use of the scientific method to discover truth.
- The term can also be used figuratively to describe any place or situation that allows for experimentation and the trial of new, innovative ideas.
The word laboratory, often shortened to the more casual 'lab,' refers to a specialized and highly controlled environment designed specifically for the purposes of scientific research, experimentation, and measurement. It is not merely a room with tools; it is a sanctum of inquiry where the physical world is systematically questioned and analyzed. When people use the term laboratory, they are usually referring to a space that is distinct from the natural world or a standard office because of its rigorous adherence to safety standards, cleanliness, and the presence of specialized equipment such as microscopes, centrifuges, and spectrometers. In a laboratory, variables are isolated so that scientists can observe the effects of a single change, which is the cornerstone of the scientific method. The term is utilized across a vast array of disciplines, including chemistry, physics, biology, and even social sciences or computer science, where 'digital laboratories' allow for the testing of code or human behavior in simulated environments. People use this word when they want to emphasize the precision and technical nature of the work being performed. For instance, a medical doctor might send a blood sample to a laboratory to get an objective analysis that cannot be performed during a standard physical examination. In industrial settings, a laboratory is where products are tested for quality control before they reach the consumer, ensuring that every batch of medicine or every new alloy meets strict safety specifications.
- The Controlled Environment
- A laboratory provides the necessary infrastructure to keep conditions like temperature, humidity, and light constant, which is vital for reproducible results.
- The Role of Specialized Equipment
- Unlike a kitchen or a workshop, a laboratory contains instruments designed for extreme precision, often measuring substances at the molecular or atomic level.
- The Human Element
- Technicians and researchers in a laboratory follow strict protocols and ethical guidelines to ensure that their findings are both accurate and responsible.
The researchers spent countless hours in the laboratory to ensure the vaccine was both safe and effective for public use.
Beyond the physical space, the word 'laboratory' can also be used metaphorically. It might describe a situation or a place that provides an opportunity for experimentation and new ideas. For example, a city might be called a 'social laboratory' if it is implementing new policies to see how they affect the population. However, in its most literal sense, the laboratory is the birthplace of modern technology and medicine. From the discovery of penicillin to the development of the silicon chip, the laboratory has been the essential theater for human progress. When discussing a laboratory, one often hears associated terms like 'sterile,' 'protocol,' 'specimen,' and 'analysis.' These words collectively paint a picture of a place where guesswork is replaced by evidence and where the unknown is systematically made known. In contemporary society, the laboratory has moved from the basement of the eccentric 'mad scientist' to the heart of global corporations and universities, representing a multi-billion dollar industry that fuels innovation. Whether it is a high-security biosafety level 4 lab handling dangerous pathogens or a high school chemistry lab where students learn the basics of reactions, the core essence remains the same: a dedicated space for the pursuit of empirical truth through disciplined practice.
Without the rigorous testing conducted in the laboratory, we would have no way of knowing the environmental impact of these new chemicals.

Using the word laboratory correctly involves understanding its syntactic role as a noun and the common verbs and adjectives that accompany it. In a sentence, it typically functions as the location where an action happens or the object of a preposition. Common verbs that precede it include 'work in,' 'conduct experiments in,' 'manage,' 'equip,' or 'visit.' For example, one might say, 'She works in a high-tech laboratory,' or 'The team conducted their research in the university laboratory.' Adjectives are frequently used to specify the type or quality of the facility, such as 'medical,' 'chemical,' 'forensic,' 'state-of-the-art,' 'underground,' or 'sterile.' These modifiers help provide a clearer picture of what kind of work is being done. For instance, 'The forensic laboratory analyzed the DNA samples,' immediately tells the reader that the context is a criminal investigation. It is also common to see the word used in compound nouns like 'laboratory equipment,' 'laboratory results,' or 'laboratory technician.' These phrases streamline communication by identifying specific items or roles within the scientific field.
- As a Subject
- The laboratory was closed for maintenance after the chemical spill occurred late Friday night.
- As an Object
- The government funded the construction of a new national laboratory to study renewable energy sources.

- All researchers must wear protective eyewear while they are inside the laboratory to prevent accidents.
After weeks of testing in the laboratory, the engineers finally found a way to increase the battery life of the device.
When writing about a laboratory, it is important to maintain the appropriate level of formality. In a formal scientific paper, you would write, 'The samples were transported to the laboratory for further analysis.' In a more informal setting, such as a blog post or a conversation, you might say, 'I'm heading to the lab to check on my cultures.' The word also appears in various possessive forms, such as 'the laboratory's findings' or 'the laboratory's reputation.' This indicates that the laboratory itself, as an institution or a collective of scientists, owns or is responsible for certain outcomes. Furthermore, the word can be used in the plural, 'laboratories,' when referring to multiple facilities, such as 'The university has several laboratories dedicated to different branches of engineering.' Pay attention to the definite article 'the' versus the indefinite article 'a.' 'The laboratory' usually refers to a specific, known facility, whereas 'a laboratory' refers to any such facility in general. This distinction is crucial for clarity in technical writing.
It is essential to maintain a clean environment within the laboratory to prevent cross-contamination of biological samples.

In the real world, the word laboratory is ubiquitous, appearing in news broadcasts, popular entertainment, educational settings, and corporate environments. If you watch a nightly news program, you will often hear it in the context of health and medicine. Reporters might discuss a 'laboratory-confirmed case' of a virus or describe how a 'laboratory breakthrough' has led to a new treatment for a chronic disease. In these instances, the word serves as a hallmark of credibility, suggesting that the information has been verified through rigorous scientific testing rather than being mere hearsay. In the world of crime dramas and thrillers, the 'crime laboratory' or 'forensics lab' is a central character in itself. Television shows like *CSI* or *Bones* have popularized the image of the laboratory as a place where high-tech gadgets and brilliant scientists solve mysteries by analyzing microscopic evidence. This has led to the 'CSI effect,' where the public's perception of the laboratory is sometimes more glamorous and instantaneous than the reality of slow, methodical scientific work.
- Academic Settings

In an educational context, students encounter the word 'laboratory' as part of their weekly schedule. A 'lab session' is a required component of many science degrees, where students are expected to apply the concepts they've learned in lectures. Teachers will often say, 'Remember to bring your lab coats to the laboratory tomorrow,' emphasizing the practical and safety-oriented nature of the space. In the business world, 'R&D laboratories' (Research and Development) are the engines of innovation. When a company announces a new product, they often highlight the 'years of laboratory research' that went into its creation to justify its price or its claims of superiority. You might also hear the word in the context of food safety; for example, a restaurant might mention that their ingredients are 'laboratory-tested' to ensure they are organic or free from allergens. Even in the beauty industry, brands often use terms like 'clinically proven' or 'laboratory-developed' to give their products a sense of scientific authority and effectiveness. In all these contexts, the word 'laboratory' functions as a powerful signifier of truth, precision, and the modern scientific era.

One of the most frequent mistakes people make with the word laboratory is related to its spelling. Because of how it is often pronounced (especially in American English), people tend to omit the 'o' in the middle, resulting in the incorrect spelling 'labratory.' It is important to remember that the word is derived from 'labor,' so keeping that base word in mind can help you remember the 'o.' Another common spelling error is swapping the 'a' and 'o,' or forgetting the 'y' at the end. In terms of pronunciation, learners often struggle with the differing stress patterns between British and American English. In American English, the primary stress is on the first syllable (LAB-ra-tory), and the 'o' is often swallowed or pronounced as a schwa. In British English, the stress is on the second syllable (la-BOR-a-tory), which can make the word sound almost unrecognizable to someone only familiar with the American version. Misplacing these stresses doesn't usually prevent understanding, but it can mark a speaker as non-native or unfamiliar with a specific dialect.
- Confusing with 'Lavatory'
- This is a classic and potentially embarrassing mistake. A 'lavatory' is a bathroom or toilet, while a 'laboratory' is for science. They sound similar, but their functions are vastly different!
- Incorrect Pluralization
- Some learners try to make it plural by just adding 's' (laboratorys), but like many words ending in 'y' preceded by a consonant, the 'y' changes to 'ies' (laboratories).
- Misusing 'Lab' in Formal Writing
- While 'lab' is common in speech, using it in a formal thesis or a professional business proposal can come across as lazy or overly casual.
Incorrect: He went to the labratory to wash his hands. Correct: He went to the laboratory to conduct his research.
Another mistake involves the countability of the word. Since 'laboratory' is a countable noun, it must be used with an article (a, an, the) or in plural form. You cannot say 'I am going to laboratory.' You must say 'I am going to the laboratory.' Additionally, learners sometimes confuse 'laboratory' with 'clinic.' While some clinics have laboratories inside them, a clinic is primarily for seeing patients, whereas a laboratory is primarily for testing samples or conducting research. Using them interchangeably can lead to confusion in a medical context. Finally, there is the issue of 'laboratory' vs 'workshop.' A workshop is typically for physical labor, building things, or manual crafts, while a laboratory is specifically for scientific or technical inquiry. While both involve 'labor,' the context of that labor is what distinguishes them. Ensuring you use the right term for the right environment is key to precise communication in English.
Incorrect: The university has many laboratorys. Correct: The university has many laboratories.
Confusing laboratory with 'lavatory' is a common slip of the tongue for beginners; practice the 'o' sound to distinguish them.
- The 'Lab' Trap
- Relying too heavily on the abbreviation 'lab' can prevent you from mastering the spelling and pronunciation of the full word.
- Over-generalizing the Term
- Not every room with a computer is a laboratory; if no experimentation or systematic testing is happening, 'office' or 'studio' might be better.
Remember: A laboratory is for science; a lavatory is for silence (and other things)!
The scientist was very particular about the organization of her laboratory, as even a small error could ruin months of work.
While laboratory is a very specific term, there are several related words that might be more appropriate depending on the context. One of the most common alternatives is 'research center' or 'research facility.' These terms are often used for larger institutions that might house multiple laboratories. For example, 'The National Research Center' sounds more expansive than 'The National Laboratory.' Another similar word is 'workshop,' though as mentioned before, this usually implies manual labor or building things rather than scientific experimentation. In the arts, the equivalent of a laboratory is a 'studio,' where artists experiment with different media and techniques. In a medical context, you might hear the word 'clinic' or 'diagnostic center,' which focuses on the application of science to patient care. For very specialized science, you might use terms like 'observatory' (for astronomy), 'hothouse' (for botany), or 'testbed' (for engineering and software development).
- Laboratory vs. Workshop
- A laboratory focuses on discovering 'how' and 'why' things work through testing, while a workshop focuses on 'making' things work through physical construction.
- Laboratory vs. Studio
- A studio is a place for creative expression and artistic production, whereas a laboratory is a place for empirical evidence and scientific production.
- Laboratory vs. Clinic
- A clinic is where healthcare professionals treat patients directly; a laboratory is where they analyze the data behind that treatment.
While the engineers worked in the laboratory to refine the engine's design, the mechanics in the workshop were busy assembling the prototype.
In some contexts, the word 'department' might be used, such as the 'Chemistry Department,' which encompasses both the classrooms and the laboratories. In software development, the term 'sandbox' is a digital equivalent of a laboratory, a safe space where code can be tested without affecting the main system. Similarly, a 'pilot plant' is a small-scale industrial laboratory where new manufacturing processes are tested before full-scale production begins. Understanding these nuances helps you choose the most precise word for your writing. If you want to emphasize the experimental and tentative nature of a project, 'laboratory' is often the best choice. If you want to emphasize the established, institutional nature of a place, 'research facility' might be better. Synonyms like 'testing ground' or 'proving ground' are also useful when talking about new ideas or technologies in a figurative sense. By diversifying your vocabulary, you can convey more specific meanings and avoid repetitive language in your descriptions of scientific and creative spaces.

In the UK and US, 'lab' is almost always used in conversation. Using the full word 'laboratory' in a casual chat might sound a bit too formal or robotic.

Summary
A <strong class='text-violet-600'>laboratory</strong> is more than just a room; it is a dedicated space where precision and control allow for the discovery of scientific truths. For example, 'The new vaccine was developed after months of rigorous testing in the high-security <mark class='bg-emerald-200 dark:bg-emerald-800 px-0.5 rounded'>laboratory</mark>.'
- A laboratory is a specialized, controlled environment designed for scientific research, experimentation, and the precise analysis of substances using technical equipment and rigorous protocols.
- Commonly abbreviated as 'lab,' these facilities are essential in fields such as medicine, chemistry, and forensics to verify facts and develop new technologies safely.
- Whether in a school or a multi-billion dollar corporation, a laboratory emphasizes safety, cleanliness, and the systematic use of the scientific method to discover truth.
- The term can also be used figuratively to describe any place or situation that allows for experimentation and the trial of new, innovative ideas.
Remember the 'Labor'
Always start with the word 'labor' (work) when you spell laboratory. If you can spell labor, you just need to add '-atory' at the end. This prevents the common mistake of writing 'labratory'.
Stress the First (US)
If you are in the US, emphasize the first part: LAB-ra-tory. This will make you sound natural to American speakers who often shorten the middle of the word.
Stress the Second (UK)
If you are in the UK, emphasize the second part: la-BOR-a-tory. This is the standard British pronunciation and sounds very professional in a UK context.
Use 'Lab' for Speed
In a fast-paced environment like a hospital or a tech startup, people almost always use the word 'lab.' Don't be afraid to use it to keep up with the conversation.
例文
I need to drop by the laboratory to pick up my medical test results.
