A pipetting robot is an automated device used in laboratories to accurately transfer liquids. It is designed to perform repetitive tasks, such as dispensing precise volumes of liquids into test tubes or plates, which helps reduce human error and increase efficiency in experiments. These robots can be programmed to handle various liquids and can work with different types of laboratory equipment, such as microplates and test tubes. By automating the pipetting process, researchers can save time and focus on more complex tasks, ultimately improving the overall productivity of scientific research.
