First, install the suction head. In the laboratory where pipettes are frequently used, the sound of tapping the tip can often be heard one after another, which adds a bit of music to the boring laboratory life. Upon closer inspection, it turned out that the user was afraid that the pipette tip could not be tightened tightly. After the pipette tip was mounted on the pipette, it was tapped a few times in the pipette tip box, hoping to ensure the sealing of the pipette through this impact Sex. What's wrong with this operation? First, under the impact of the impact, the tip may be deformed and affect the accuracy of the pipetting; second, the part of the pipette handle that contacts the tip will become rough and difficult to guarantee the tightness after repeated strong friction And in order to achieve a good seal, a greater impact force is needed, and the vicious cycle begins. Third, the sleeves of small-scale pipettes are relatively thin. Under the devastation of continuous impact, it is likely to become fishing Hook; Fourth, sometimes this impact force is greater than the force that the pipette falls on the ground, and some precision parts in the pipette may be overwhelmed and may strike at any time. Second, the suction angle ...
