Background

Over a hundred years ago, the remote, laboratory researchers began using pipettes to transfer liquids. The pipette is a hollow glass tube, and one to N scales are marked on the pipette. The glass tube is inserted into the liquid, the other end of the tube is sucked into the tube by a nozzle or an ear washing ball, and the scales on the glass tube tell the user how much liquid is in the tube. After the desired amount has been drawn, the pipette is closed with the thumb and the tube is placed in another container to allow the liquid in the tube to flow into the second container, thus transferring the liquid. However, with the advancement of society, researchers have found that this tubing is simply not useful, slow, and difficult to clean, resulting in the birth of a pipette. That is, the pipettes and pipettes function identically, with the only few differences being: one, higher accuracy (based on the higher accuracy in the new pipette compared to the old pipette); secondly, the efficiency is higher (easy operation); thirdly, the structure is more complex (the pipette is a tube, and the pipette is composed of dozens of components); and fourthly, the function is stronger (besides the liquid transfer, many pipettors also have many functions). The liquid transfer device is a device for quantitatively transferring liquid, and is widely used in the fields of biology, chemistry and the like, and is a common tool in clinical diagnosis experiments, biotechnology laboratories, pharmaceutical and chemical laboratories, environmental laboratories and food laboratories.
