Machines that help people move liquids from here to there are often called liquid handlers. These can be very important in mobility, in laboratories, hospitals and factories. Rather than using a hand to pour or pass liquids, a job that can be both sloppy and slow, liquid handlers do such work quickly — and with precision. Sometimes these can move small amounts of liquid, such as a drop, and sometimes larger amounts, depending on what it needs to do. For instance, in a laboratory, scientists might use a Liquid Handling to mix chemicals for experiments. In a hospital, they might be useful transporting medications for patients. These machines save time and minimize errors, making life easier for all concerned.
