Definition of “Pipette”
The word “pipette” has two primary functions in the English language: as a noun and as a verb. Understanding both definitions is crucial for accurate usage.
“Pipette” as a Noun
As a noun, a pipette refers to a laboratory tool used to accurately measure and transfer small volumes of liquids. It’s typically a glass or plastic tube, often graduated, allowing for precise measurements. Pipettes are essential in various scientific fields, including chemistry, biology, and medicine, where accurate liquid handling is critical for experiments and procedures.
“Pipette” as a Verb
As a verb, pipette means to transfer or measure liquid using a pipette. It describes the action of using this laboratory tool. The verb form is commonly used in scientific and technical contexts to describe the precise transfer of liquids from one container to another. For example, a researcher might “pipette 5 milliliters of the solution into the test tube.”
Structural Breakdown
Understanding the structural elements of “pipette” as both a noun and a verb will help you use it correctly in various sentence constructions.
Noun Structure
As a noun, “pipette” follows standard noun rules. It can be singular or plural (“pipettes”).
It can be preceded by articles (a, an, the) or possessive pronouns (my, your, his, her, its, our, their). It can also be modified by adjectives to describe its characteristics or type (e.g., “a glass pipette,” “a volumetric pipette”).
Verb Structure
As a verb, “pipette” can be conjugated in different tenses (present, past, future) and aspects (simple, continuous, perfect). It can also be used in the active or passive voice.
The verb form “pipette” usually takes a direct object, which specifies the liquid being transferred. For instance, “She pipetted the solution” (solution is the direct object).
It can also be followed by a prepositional phrase indicating the destination or quantity, such as “He pipetted the sample into the vial” or “They pipetted 2 ml of the reagent.”
Types or Categories of Pipettes
Pipettes come in various types, each designed for specific applications. Understanding these categories can further clarify the context in which the word “pipette” is used.
Glass Pipettes
Glass pipettes are traditional pipettes made from glass. They are often reusable and can be sterilized, making them suitable for applications where contamination is a concern.
While less common now due to the rise of plastic alternatives, they are still used in some laboratories.
Plastic Pipettes
Plastic pipettes are disposable and widely used in modern laboratories. They eliminate the need for cleaning and sterilization, reducing the risk of contamination.
They are usually made of polyethylene or polypropylene.
Micropipettes
Micropipettes are designed to measure and transfer extremely small volumes of liquids, typically in the microliter range (µL). They are essential in molecular biology and other fields where precise measurements at small scales are required.
These often use disposable tips.
Volumetric Pipettes
Volumetric pipettes, also known as bulb pipettes, are designed to deliver a single, specific volume of liquid with high accuracy. They have a bulb-shaped reservoir in the middle and are calibrated for a specific volume, such as 10 mL or 25 mL.
Graduated Pipettes
Graduated pipettes, also known as measuring pipettes, have markings along their length, allowing for the measurement and delivery of variable volumes of liquid. They are less accurate than volumetric pipettes but offer more flexibility in volume selection.

- Adjectives: Use adjectives to describe the type or characteristics of the pipette (e.g., “a glass pipette,” “a calibrated pipette”).
Verb Usage Rules
- Tense: Use the correct tense form of the verb to match the time frame of the action (e.g., “pipetted” for past tense, “is pipetting” for present continuous tense).
- Subject-Verb Agreement: Ensure the verb form agrees with the subject of the sentence (e.g., “She pipettes,” “They pipette”).
- Direct Object: Usually, include a direct object to specify what is being transferred (e.g., “She pipetted the solution”).
- Prepositional Phrases: Use prepositional phrases to indicate the destination or quantity (e.g., “He pipetted the sample into the vial,” “They pipetted 2 ml of the reagent”).

Advanced Topics
For advanced learners, here are some more complex aspects of using “pipette.”
“Pipette” in the Passive Voice
While less common, “pipette” can be used in the passive voice. This construction shifts the focus from the person performing the action to the liquid being transferred.
For example: “The solution was pipetted into the test tube.” In this sentence, the focus is on the solution, not on who did the pipetting. Passive voice is often used when the actor is unknown or unimportant.
Idiomatic Expressions (Rare)
There are no common idiomatic expressions that directly use the word “pipette.” Its usage is primarily confined to technical and scientific contexts. However, in a metaphorical sense, one might use “pipette” to describe the precise and controlled distribution of something.
This is rare and would depend heavily on context for its meaning to be understood.
Frequently Asked Questions (FAQ)
Here are some frequently asked questions about using “pipette” in sentences.
- Is “pipette” a countable or uncountable noun?
“Pipette” is a countable noun. It has both singular (“pipette”) and plural (“pipettes”) forms, and it can be used with articles (a, an, the).
- Can “pipette” be used in informal contexts?
While “pipette” is primarily used in scientific, medical, or technical contexts, it can be used in informal settings if you are discussing a relevant topic. For example, if you are discussing a science project with a friend, it would be appropriate to use the word “pipette.”
- What is the difference between “pipette” and “dropper”?
Both “pipette” and “dropper” are used to transfer liquids, but pipettes are generally more precise and calibrated for specific volumes. Droppers are less accurate and are typically used for transferring approximate amounts of liquid.
- How do you conjugate “pipette” in different tenses?
Here’s a brief overview of the conjugation of “pipette”:
- Present Simple: I/You/We/They pipette; He/She/It pipettes
- Past Simple: I/You/He/She/It/We/They pipetted
- Future Simple: I/You/He/She/It/We/They will pipette
- Present Continuous: I am pipetting; You/We/They are pipetting; He/She/It is pipetting
- Past Continuous: I/He/She/It was pipetting; You/We/They were pipetting
- Present Perfect: I/You/We/They have pipetted; He/She/It has pipetted
- Past Perfect: I/You/He/She/It/We/They had pipetted
- Is it correct to say “pipette out” the solution?
While not strictly incorrect, it’s more common and concise to simply say “pipette the solution.” The addition of “out” is often redundant, as the act of pipetting implies transferring something out of one container and into another.
- What is the most accurate type of pipette?
Volumetric pipettes are generally considered the most accurate type of pipette for delivering a specific volume, as they are calibrated to deliver a single, precise amount of liquid.
- Can “pipette” be used to describe transferring solids?
No, “pipette” is specifically used for transferring liquids. For transferring solids, other tools such as spatulas or scoops are used.
- What are some synonyms for “pipette” (as a verb)?
While there aren’t direct synonyms for “pipette” as a verb that capture the same level of precision, you could use phrases like “transfer with a pipette,” “measure and transfer,” or “dispense using a pipette” depending on the context.
