Frequently Asked Questions

What is the history behind Pasteur pipettes?

Pasteur pipettes have a rich history dating back to the 19th century. These long, slender glass tubes were named after the renowned French scientist Louis Pasteur. He pioneered the use of these pipettes in his groundbreaking research on microbes and vaccination. Due to their precise measurements and ease of use, Pasteur pipettes quickly became a staple tool in laboratories worldwide. Today, they continue to play a crucial role in various scientific experiments and medical procedures, showcasing the enduring legacy of Louis Pasteur’s contributions to the field of science.

How do Pasteur pipettes differ from micropipettes?

Pasteur pipettes and micropipettes may seem similar, but they have distinct differences. Pasteur pipettes are more traditional and are used for transferring liquids in small volumes manually. On the other hand, micropipettes are more modern and precise, allowing for accurate measurement and dispensing of microliter volumes. While Pasteur pipettes require the user to control the liquid flow by mouth suction, micropipettes have built-in mechanisms for precise and consistent dispensing. So, depending on the need for accuracy and convenience, one can choose between Pasteur pipettes and micropipettes.

Can Pasteur pipettes be autoclaved?

Yes, Pasteur pipettes can definitely be autoclaved without any issues. Autoclaving is a common method used to sterilize laboratory equipment including pipettes. This process helps ensure that the pipettes are free from any contaminants or microorganisms, making them safe to use in experiments. When autoclaving Pasteur pipettes, it is important to follow the proper protocols and guidelines to ensure effective sterilization. By autoclaving your Pasteur pipettes, you can maintain a clean and sterile working environment in your laboratory, promoting accurate and reliable results in your research.
