Pipette workstation, as a modern laboratory equipment, is increasingly widely used in liquid handling, sample analysis and other fields. The core component of pipette workstation is the suction head, and its characteristics and working principle are very important to the accuracy and efficiency of the experimental results.

As a key component of pipette workstation, the design features of the suction head are mainly reflected in the following aspects. First, the suction head is usually made of a material, such as medical plastic or glass, to ensure that it does not produce contamination or chemical reactions when it comes into contact with various chemical agents. Second, the shape of the suction head is exquisitely designed, and it usually presents a specific taper in order to easily absorb and release the liquid. In addition, the suction head has good elasticity and durability, and can maintain its original shape and function after multiple uses.

The working principle of the pipette workstation mainly depends on the interaction between the suction head and the liquid. When the suction head comes into contact with liquid, the air pressure inside the suction head can be controlled through the control system of the pipette workstation. When negative pressure is formed inside the suction head, the external liquid is sucked inside the suction head under the action of atmospheric pressure. On the contrary, when the internal pressure of the suction head returns to positive pressure, the liquid is pushed out of the suction head to complete the pipetting operation.
