Pasteur Pipettes: Types, Uses and Properties
Pasteur pipettes, often called dropper pipettes, are an essential piece of equipment for any laboratory. Their simplicity and versatility make them ideal for precisely dispensing and transferring small amounts of liquids. But what is really hidden behind these unassuming tools? In this article, we will look at the different types of Pasteur pipettes, their uses, and the properties that make them so unique.
At the beginning it is worth emphasizing that Pasteur pipettes are available in various forms and materials, which allows them to be widely used in many fields of science and industry. From classic, glass pipettes, which are associated with traditional methods, to modern, plastic versions, offering greater flexibility and safety. Each of these types has its own unique features, which we will discuss later in the article.
As we delve deeper into the subject, we will also learn how to choose the right Pasteur pipette for your specific lab needs. Is it crucial sterility, capacity, or maybe Material, what is the pipette made of? The answers to these questions will help you fully utilize the potential of these inconspicuous but incredibly useful tools.
What are Pasteur pipettes?
Pasteur pipettes are essential tools in every laboratory, enabling precise transfer of small amounts of liquids. They are named after Louis Pasteur, the eminent French scientist who helped popularize them. These simple but extremely functional tools come in two main variants:
-
glass Pasteur pipettes – chosen where high precision and sterilization option are key,
-
plastic Pasteur pipettes – made of polyethylene, disposable, which reduces the risk of contamination and is more economical.
The decision to choose between glass and plastic Pasteur pipettes depends on the specific requirements of the laboratory. Glass pipettes are more durable and can be reused multiple times after proper sterilization, making them an ideal choice in situations where the utmost cleanliness is required. In turn, plastic pipettes are more flexible and safer, especially where there is a risk of glass breakage.
Characteristics of Pasteur pipettes
Pasteur pipettes are characterized by simple construction – a thin tube with a narrow opening allows for precise dosing of fluids, which is crucial in many laboratory experiments.

How to choose the right Pasteur pipette?
Choosing a Pasteur pipette can seem a bit complicated at first. However, there are a few key things you can do to make the process easier. Depending on your lab’s needs, factors such as Material, capacity or sterility can make a huge difference. Let's take a closer look at how to choose the best pipette so that your lab work is not only effective but also safe.
Plastic vs. Glass Pipettes
One of the first questions that arises is: plastic or glass? The choice depends on the specific needs of the laboratory:
-
Plastic pipettes (polyethylene) are disposable, which reduces the risk of contamination and is more economical. Additionally, their flexibility and safety make them ideal where there is a risk of glass breakage.
-
Glass pipettes (soda-lime glass) are more durable and can be reused many times if properly sterilized. They are ideal for long-term use, but require more care.
The choice between these two options depends on the specific needs of your laboratory and your preferences regarding safety and cost.
Choosing the right capacity
Another important issue is Pasteur pipette capacity. Various variants are available, such as:
-
1ml
-
2ml
-
3ml
-
5ml
Choosing the right capacity depends on how much liquid you want to transfer. If you need precision and every drop counts, smaller capacities are a better choice. However, if you are transferring larger amounts of liquid, larger capacities provide convenience and efficiency.
Sterile or non-sterile?
Finally, you need to decide whether you need sterile or non-sterile pipettes. The choice depends on the specific requirements of the experiment:
-
Sterile pipettes are essential in research where purity and freedom from contamination are essential – for example, genetic or microbiological research. They are usually individually packaged and free from DNase, RNase and pyrogens.
