A measuring tube is a device used to measure and transfer precise amounts of liquid. It is also known as a PIPETTE or pipet. A PIPETTE is a laboratory tool used to transfer small amounts of liquid, usually between 0.5 and 10 milliliters. A pipet is a similar device, but it is typically used to measure larger volumes of liquid, usually between 10 and 100 milliliters. Both devices are commonly used in scientific experiments and laboratory work.
