In today's era of rapid biotechnology development, pipettes are a very common basic laboratory tool for people working on experiments! At the same time, because of the self-development of the pipette, its accuracy is getting higher and higher, and its reliability is slowly being accepted by the majority of experimental personnel! It can be said that the pipette is a tool that every experimenter is familiar with and who have completely mastered the method of use.

In fact, many experimenters are not very familiar with the correct operation of pipettes.

So it is almost impossible to say that almost 99% of the experimental personnel need to pay attention to some details of the pipette use process, or even if it is clear, it may not be able to pay attention to these details in actual use. And often, the accuracy of pipetting results is often affected by this! One of the most important details we have to say here is the pre-lubrication preparation before pipetting!

Many times, the user finds that the pipette feels less smooth when used. Seriously, even when the liquid button is pressed or the liquid button is released, it feels that the button moves up and down fast or has a pause. A common phenomenon is as follows:

1.When the pipette is operated to take liquid or drain, the button does not move up and down smoothly;

2.When the button is pressed, when the finger is removed, it is found that the button cannot return quickly or obviously upwards much faster than the new pipette;

3.When the pipette was taken, it was found that the liquid obtained did not reach the set capacity obviously;

4.pipetting results of poor pipetting results, but after several consecutive uses, its stability slowly changed again;
