Suction box manufacturers believe that to obtain test results safely and accurately, it is inseparable from the "auxiliary" of many attributes of laboratory consumables. Suction boxes are commonly used in biological laboratories to house suction heads for medical tests. The suction box is generally made of PP material. The suction box is made of modified PP material, which is non-toxic and tasteless and can withstand 121 autoclaved sterilization without deformation. Good dimensional stability, durability and corrosion resistance.

Suction box manufacturers believe that in laboratories where pipettes are frequently used, the sound of one tap after another can often be heard, adding some musical flavor to the dull life of the laboratory. However, under impact, the suction head may deform and affect the pipetting accuracy. Secondly, after many times of strong friction, the part of the pipette sleeve handle in contact with the suction head will gradually become rough, and it is difficult to ensure the tightness. In order to achieve a good tightness, greater impact force is needed, and a vicious cycle begins. Third, a pipette with a small range has a thin handle and is likely to become a fishhook under constant impact. Fourth, sometimes the impact force is greater than the pipette landing force, some precision parts in the pipette may be overwhelmed at any time and impact
