Serological pipettes are a type of laboratory pipette that are commonly used for transferring precise volumes of liquid between containers. They are typically made of plastic, such as polystyrene or polyethylene, and come in various sizes ranging from 1 ml to 50 ml. Serological pipettes have a graduations or volume markings along their length that allow the user to accurately measure the volume of liquid being transferred.
These pipettes have a bulbous, tapered end, which allows the user to draw in the liquid by creating a vacuum and then dispense it by releasing the vacuum. Serological pipettes are commonly used in biological and medical laboratories for applications such as cell culture, drug discovery, and diagnostic testing. They are also used in the food and beverage industry, as well as in environmental testing. Overall, serological pipettes are an essential tool for laboratory work that enable precise liquid handling and transfer, which is critical for many types of research and analysis.
