Serological pipettes are specialised laboratory tools designed for accurately measuring and transferring larger volumes of liquid, typically ranging from 1 to 100 millilitres. Commonly used in clinical and research laboratories, these pipettes are particularly suited for serological tests, cell culture work, and other applications requiring precise liquid handling. Serological pipettes are often made from sterilised, disposable plastic to ensure contamination prevention, although reusable glass options are also available. They feature graduated markings along their length for easy volume measurement and typically come with a wide opening to facilitate smooth liquid transfer. Some models are equipped with a bulb for manual aspiration, while others may be used with a pipette pump for greater accuracy and ease of use. By providing reliable liquid transfer, serological pipettes play a crucial role in various scientific procedures, ensuring accurate and consistent results.
