For researchers, these small gunheads are not only experimental tools but also partners in exploring the unknown. They help us to accurately sample in small amounts of samples, whether it's DNA microextraction or meticulous addition of cell culture medium, 20 ul pipette tips can always complete tasks with unimaginable precision.

In the field of molecular biology, PCR (polymerase chain reaction) technology is an important research method. During the PCR process, it is necessary to use trace and precise DNA templates, primers, enzymes, and other reagents. The 20 ul pipette tips, due to their precise pipetting ability, can ensure the accurate addition of these key reagents, which is crucial for the success or failure of the experiment.

Especially in real-time fluorescence quantitative PCR (qPCR), this is an indispensable experimental tool. They can help researchers achieve high-precision reagent allocation in trace samples, thereby improving the accuracy of experiments.

Cell culture is a fundamental step in biological research, and it also plays an important role in the cell culture process. In cell proliferation, fluid exchange, and other operations, due to its small size, 20 ul pipette tips can reduce damage to cells and improve cell survival rate. 

In addition, in experiments such as cell crawling, 20 ul pipette tips are often used to drop cell suspensions onto glass slides to ensure uniform distribution of cells and improve the reliability of experimental results.
