The petri dish is used to grow microorganisms and is in the shape of a low-height cylindrical glassware with a glass lid on top. When cultivating microorganisms, pour the prepared medium into a petri dish, wait for the medium to solidify, and then inoculate the microorganisms on it. Therefore, when the petri dish is used up, it is still more troublesome to deal with, and the medium with solid glue in the petri dish must be poured out first. Because the medium is generally in the shape of solid glue, it is easy to stick to the glass, it is difficult to pour it clean, and it needs to be brushed repeatedly with a brush. Not only that, but petri dishes are often marked with numbers underneath them, and they need to be scrubbed off. Therefore, the cleaning of petri dishes is more time-consuming and labor-intensive. As for sterilization and disinfection, it is another process of petri dishes, which needs to be dried after washing, and then wrapped in something like newspaper or kraft paper in a dozen or so tubes, and put them in an autoclave for disinfection. A dozen or so are bandaged in a tube, of course, it is also a lot of work.

So as soon as Su Lingfei's words came out, she purely wanted Zhang Weidong to come over and work overtime at night. [Search for the latest update.]

"Okay, no problem!" Zhang Weidong nodded calmly.

Su Lingfei thought that her words would definitely force Zhang Weidong to jump up and down, at least she should show a crying expression, of course, it would be better if she could ask her to raise her noble hand. Unexpectedly, Zhang Weidong still looked unfazed, as if this bit of utensils was nothing to him.

"Then it's troublesome Mr. Zhang, remember to hurry up, I'm going to use it tomorrow." Su Lingfei said with a smile on her face, but she secretly gritted her teeth in her heart, and opened her mouth to say that you will die if you are going to suffer? What are you doing? What are you dragging? Okay, this is your own guilt, my aunt and grandmother want to see what time you are going to be busy!

"Don't worry, this thing won't bother me. Zhang Weidong glanced at the utensils on the table and said lightly.

Zhang Weidong is not a fool, and now of course he sees some of Su Lingfei's intentions. However, since he is one of the members of the research group, Zhang Weidong doesn't think it's anything, after all, someone has to do it, right? In this kind of thing, Zhang Weidong will never disdain to deal with a woman, and this thing really can't be difficult for him.

Seeing that Zhang Weidong was still cool and coaxing at this time, Su Lingfei almost couldn't help but run away, revealing her "insidious" true face. But in the end, Su Lingfei still smiled and said, "Okay, you are busy, I still need to prepare some buffer solution." ”

After speaking, Su Lingfei walked to the other countertop and began to configure the buffer solution, but the good-looking peach blossom eyes secretly spied on Zhang Weidong's side.

At this look, Su Lingfei was immediately dumbfounded!

I saw that Zhang Weidong's hands seemed to have magic power, and he casually grabbed a petri dish on the mountain of petri dishes, and a petri dish was just sandwiched between his fingers .xzsj8. and his fingers .xzsj8. Two hands, ten fingers.xzsj8.The head grabbed so casually, and he grabbed eight petri dishes in a neat and orderly manner.

This is nothing, what made Su Lingfei most dumbfounded was that Zhang Weidong's hands gently shook the trash can, and the culture medium that was usually difficult to get down was like a round cake-shaped jelly, falling into the trash can. As soon as the medium came off, the bottom of the dish was clean and there was no residue in sight.

Originally, it would take an hour or two to clean the medium of four or five hundred petri dishes, but when Su Lingfei was dumbfounded, Zhang Weidong had already processed fifty or sixty of them, and at this rate, it was estimated that within five minutes, Zhang Weidong would be able to clean up all the culture media in the four or five hundred petri dishes.

In fact, this is still Zhang Weidong who doesn't want to be too shocking, he just summons his hand to be dexterous, otherwise he really wants to use his true yuan mana to exert his skills, and it is not a matter of seconds to clean up these culture mediums.

But Rao is Zhang Weidong has been extremely restrained, Su Lingfei is still dumbfounded, and finally couldn't hold it back, walked over and stretched out her fingers like onion jade to clip the petri dish, but no matter how hard she tried, she couldn't pick up four with one hand, let alone grab four with one hand like Zhang Weidong.

Unconvinced, Su Lingfei, who didn't believe in evil, took another petri dish and shook vigorously on the trash can, but she didn't shake off the culture medium even if she broke her wrist, and finally Su Lingfei, who was depressed and helpless, took the petri dish and gently slammed it against the edge of the trash can. This time, the culture medium was finally put down, but the walls of the petri dish were covered with residue, like Zhang Weidong, every petri dish that he shook was not stained with any residue, and it was clear.

Su Lingfei naturally didn't believe in evil, and took a petri dish and pounded it, but the result was still the same, so angry that she knocked on the trash can with the petri dish.

With a bang, the petri dish finally couldn't withstand Su Lingfei's "violent" beating and shattered.

"You're really good! Okay, don't make a mess, be careful to cut your hands, you can't learn this trick. Zhang Weidong saw that Su Lingfei, a poor woman, was like an evil spirit, and she couldn't get along with a petri dish, so he couldn't help frowning slightly and said mercilessly.

Su Lingfei was so angry that her face turned blue, but she looked down at the broken petri dish in her hand, but no, pouring a medium can break the petri dish, this is not a mess, thinking about it, Su Lingfei really had the urge to pick up the glass fragment in her hand and cut it on her wrist.

Stinky boy, let's see, my aunt and grandmother don't believe that you can clean so many things in one morning! In the end, Su Lingfei hated and threw the glass fragments in her hand into the trash can, and returned to her own countertop to continue to prepare the buffer solution.

However, Su Lingfei's buffer solution had not yet been prepared, and she was immediately stimulated again. I saw Zhang Weidong, who had quickly cleaned up the culture medium, turned on the two faucets on the sink at the same time, and each hand held four petri dishes as just now. Then the fingers of both hands moved together, and eight petri dishes quickly flipped up in his hands under the tap. It was really fast and smooth, much more exciting than acrobatics. In a few moments, the eight petri dishes were washed at one time, and then Zhang Weidong raised his hand.

Like playing Frisbee, eight Petri dishes came out one after another, and then one was stacked diagonally downward, neatly lined up on the tray.

How is this possible? Su Lingfei's eyes widened, and her eyes quickly turned back and forth with the petri dishes flying through the air one after another.

Within a few minutes, nearly 100 petri dishes were neatly placed on a tray, and what was even more exaggerated was that none of the petri dishes had water beads hanging on the glass walls, which was a sign that the glassware was clean. Su Lingfei is engaged in scientific research, of course this is clear.

Fortunately, Zhang Weidong later washed the beaker and Erlenmeyer flask, but Rao was still many times faster than ordinary people.

So at noon, the piles of utensils on the table were cleaned by Zhang Weidong and placed neatly, as long as they came over in the afternoon and sterilized and disinfected, it would be completed. And Su Lingfei was full of calculations before, thinking that Zhang Weidong had to clean so many things by himself, so he had to work until the afternoon, and if he counted sterilization and disinfection, I am afraid that he would have to come over to work overtime at night.

Watching Zhang Weidong wash his hands, twist his buttocks, and raise his hands very coolly, Su Lingfei's heart swelled up with a trace of admiration for Zhang Weidong uncontrollably, and at the same time, more unwillingness and depression swelled up.

"What are you dragging, it's just a matter of being faster!" Su Lingfei said hatefully while scrubbing her hands fiercely. But although she said this, she knew very well in her heart that Zhang Weidong was definitely not just a little faster, and because of this, she was even more depressed.
