"We are doing reproducibility experiments now, so the speed will be faster. If Section Chief Jiang feels unaccustomed to it, he can raise it." Yang Rui's posture was quite low, but behind him was full of malice.

A student like Jiang De who had just graduated from the ivory tower did not know that Yang Rui would have any tricks. He stood in the main position with great enthusiasm and said, "You can command me to do it, it's okay. I used to do experiments and I'm quite proficient."

"Thinking about it, the Department of Chemistry at Hedong University seems to be very good. Section Chief Jiang often does exercises?"

"It's pretty good. There are several professors who teach very good classes. Every time someone stands to listen. You're going to take the college entrance examination this year. If you have the chance, you must try it. The atmosphere of Hedong University is completely different from other schools." Jiang De couldn't help but smile when he talked about such a proud life.

In Hedong Province, his education is considered top-notch, otherwise he would not have easily entered the Provincial Education Bureau and took on heavy responsibilities.

"If you can break the key line, you must consider it." Yang Rui smiled, but thought to himself: As for the teaching conditions in the 1980s, I believe you can do experiments. If you say you are proficient, don't underestimate the dark training in the laboratory.

After a few gossips, Yang Rui handed a round-bottom flask to Jiang De and said, "Now, pipette 150 ml of suspended substance first, then add 0.76 grams of pyrogenic gallic acid, and then 2.58 grams of potassium hydroxide. It has been prepared next to it... is it done?"

"It's almost." Although Yang Rui said only a few words, Jiang De was still busy. These experiments were so short that milliliter milligrams were accurate, because the final extract weighed only a few grams. If some were sprinkled out casually, the experiment would not be necessary.

Moreover, when no one helps, using a pipette and a mechanical analysis balance is really a big test for Jiang De, who has not done the experiment for two or three years.

He didn't participate when he first started the experiment, but now he is involved, and he feels that he has recalled it.

But the reality is that novices can't compete with experienced players no matter what.

It took Jiang De more than ten minutes to complete this part of the work.

Before he could receive a praise, Yang Rui said: "Let's continue. Now we need to add 7 ml of methanol, shake it with 55 ml of distilled water, and reflux it in 90-degree water bath for 30 minutes. Turn on the water bath first. Also remember to prepare tap water. After the water bath, it must be cooled quickly and poured into the separating funnel. Can you remember?"

Jiang De was not stupid, so he nodded reluctantly and said, "Remember."

Yang Rui continued without pause, "Next, when I reach this step, I will use petroleum ether, 40 ml, and violently shake for 5 minutes. We don't have the corresponding instrument, so we can use our hands to shake it. After doing this step, we can continuously extract and combine the extract."

After getting the extract, Yang Rui didn't say anything, because Jiang De had already started to faint. When he was distilled water, he accidentally added a drop.

Yang Rui immediately shouted: "There are too many."

Section Chief Jiang was shocked and couldn't help but repeat: "There are too many!"

In any experiment with droppers, adding more solution is the most annoying thing. If you add less, you can add more. What should you do if you add too much? If it is a mixture of two substances, you may also use the lazy method to add another substance. But most experiments, like what they do now, add more than two substances, and there are also compound reactions.

Yang Rui glanced at the jar, shook his head, then snatched the round bottom flask, poured it clean, and said, "Come again."

"This... OK." Jiang De had no choice but to listen to Yang Rui. There was only one answer to this kind of thing. No matter whether he was the section chief or the dean, he could not let the extra drop of water run out in a complete manner, and the drop of water didn't listen to him.

In order not to take the blame for the final answer, Jiang De had to obey and do it again.

This time, his speed has accelerated, which shows that the foundation is really good and the feel is a bit back.

But Yang Rui would not let him continue to do it easily, and kept urging him to constantly adjust the temperature of the water bath.

When Jiang De went to use a water bath, the temperature setting was wrong and he had to start over again.

In this way, let alone Jiang De, Ding Yaqin's face changed.

I did it twice and it was dark. Can I have a pleasant interview?

Yang Rui guessed their mood and coughed, "Let's come together, the two of them remind each other, it's not easy to make mistakes."

Jiang De nodded in a depressed manner and said yes.

So Yang Rui quickly got into battle, stood opposite Jiang De, and started operating various instruments. Not to mention his training during his postgraduate studies, even in recent times, he has done more experiments than Jiang De, not to mention that he has done several identical coenzyme extraction experiments.

In terms of speed, Yang Rui was more than twice as fast as Jiang De. The so-called mutual reminder quickly turned into Jiang De's desperate pursuit.

He is embarrassed to say that Yang Rui has made things difficult for him now, although Yang Rui is indeed making things difficult for him.

Yang Rui's expression remained unchanged, and he had already laughed in his heart.

He knows too many ways to bully newcomers in the laboratory. The simplest one is to urge him.

The more you urge, the more you make mistakes, the more you make mistakes, the more you rework, the more you rework, the slower you rework, and the slower you have the reason to urge.

Experiment is a few academic jobs that can make up for shortcomings. Generally speaking, smart people are suitable for studying pure theory, only thinking about their own brains, and not caring about other things. In the 21st century, mathematics and theoretical physics have a sense of transcendence and metaphysics. When you are in middle school, if students have not yet found the supreme sense of being ahead of the crowd, they should almost understand that they are not the material for learning mathematics and theoretical physics. The difficulty of experimenting physics is much lower, and they are a little creative and have a good foundation, so you can try it.

Of course, if you can’t handle experimental physics and want to do academic research, then you can be good at biology. After staying in this industry for a long time, you can always play a role.

Domestic graduate students have about one year of laboratory experience when they are studying for the second year of graduate school. They can do well for two years. At this time, they are pure and perfect for newcomers, whether in terms of speed or other things. On the laboratory bench, they bully whatever they want.

There are very few cases of undergraduates who can make a comeback as soon as they enter the laboratory. The better the laboratory, the more this happens. For undergraduates, they cannot recognize the instruments, so what qualifications are there to counterattack?

Although the competition in domestic laboratories is fierce, they are not cruel after all. In the laboratory in Japan and South Korea, there are all newcomers who are bullied and cannot stand jumping off the building. Unlike middle schools and primary schools, most of the ones they encounter are not violent attacks.

The experiment is not as fast as others, the data is not as accurate as others, the experimental design is not as good as others' creativity, the rework is more frequent, the waste of materials, the expenditure is overspent, the progress is lagging, the paper cannot be passed, the graduation certificate cannot be obtained, the ugly things are not favored by the tutors without friends... The more confident and inferior you are, the faster your beliefs are destroyed.

In just over ten minutes, Yang Rui walked through the process and said, "Wash the extract with distilled water to neutral, and increase anhydrous sodium sulfate in proportion. Here is a formula to calculate. We will discuss it later if you arrive..."

Jiang Deman was sweating profusely, and he didn't have time to see how Yang Rui did it again.

His head was so hiding under the experiment table.

A graduate of Hedong University’s key majors, but he couldn’t do a high school student in experiments. No matter how many objective reasons he had, the proud Jiang De would not forgive himself.

Ding Yaqin and others were also dumbfounded.

Before, when Yang Rui was doing the experiment by himself, although it was smooth, no one thought there was anything extraordinary, and thought that normal experiments should be like this.

After Jiang De took action and compared it, several people discovered Yang Rui's speed and accuracy.

Ding Yaqin didn't know how to describe the strange atmosphere at the moment, but it seems that it is incorrect to say that Xibao Middle School's "communications" are fake.

Just when others were struggling, Yang Rui quickly completed the most important saponification step, and then lay on the desktop to start drawing the yield curve of Coenzyme q10.

At this part, without Yang Rui’s explanation, it is already a very professional content.

Jiang De finally played with the round-bottom flask clearly, and Yang Rui's yield curve was calculated.

He took a peek at him twice and was embarrassed to ask Yang Rui how he calculated it. He already felt embarrassed enough.

"It's almost like that, Section Chief Jiang will check it." Yang Rui didn't say anything to ask Jiang De to continue the experiment, and the latter probably didn't want to do it anymore.

On the other hand, Yang Rui tried his best to choose uncommon formulas to calculate the yield of coenzyme q10, which made Jiang De feel extremely uncomfortable.

He studied chemistry. In the first three years, inorganic chemistry was more involved in biological aspects. It was okay to read concise and easy-to-understand formulas, but he was fooled by Yang Rui deliberately making complicated formulas.

In fact, if he repeats all the experimental steps, he can still rub something, but Yang Rui doesn't give him a chance.

Section Chief Jiang twisted his hair and read Yang Rui's answer, but he still had no experience.

Yang Rui asked someone to come in again and started cleaning. After a while, he said: "If Section Chief Jiang is interested, he might as well compare the actual yield of Coenzyme q10 and compare it with the content of the suspension, and he could also intuitively see if the yield has increased."

"Yes, that's right." Jiang De used ultraviolet spectrophotometry to measure the content, but he was very skilled.

The familiar kerosene smell of petroleum ether floated in the air, and Ding Yaqin reluctantly put on the notebook.

"600 ml of suspension liquid extracted 82 grams of coenzyme q10 crystals, which was almost 13.67%..." Jiang De calculated the number and shouted in a habitual way. He had been a little assimilated by Yang Rui's laboratory discipline.

This is the most common in a small and tense environment.

"Thirteenpoint..." The pronunciation of a bit Hedong flavor repetitions Jiang De's numbers.

Everyone, including Yang Rui, turned their heads and looked at the door.

I saw a round white fat man stretching his neck to look at the laboratory bench, while another short Chinese translator was trying to squeeze forward.

"What are the two?" Jiang De shook his coat and showed the majesty of a cadre.

"This is Mr. Frankie from the UK's Jelikon Company and is inspecting Hedong Province. I am Lu Chengcai from China's Pharmaceutical Foreign Trade Company. He is currently the translator and contact person for Mr. Frankie. This is my work certificate." The short translator skillfully took out a red-skinned notebook.

Jiang De pretended to check it out.

Ding Yaqin's eyes lit up like a fox and asked softly: "Mr. Frankie from the UK's Jelikon Company? What is your purpose in going to Westborough Middle School?"

Lu Chengcai translated it with a gusto.

Frankie said again and listened to the translator: "Mr. Frankie is inspecting medical cooperation matters. In the address book, there is a contact address for a paper. Mr. Yang Rui, is it from your unit?"

"Yang Rui?"

"Yang Rui!"

"This foreigner is here to find Yang Rui!"

Several people couldn't help but read the names.

Although some people have guessed the reason, most of the Chinese expressions in the laboratory are still vivid and bizarre, like carefully carved wax figures.
