Rebirth of the God-level Xueba

"We are doing reproducible experiments now, so the speed will be faster. If Section Chief Jiang feels uncomfortable, he can bring it up." Yang Rui's posture is quite low, but behind him is full of malice.

A student like Jiang De, who just graduated from the ivory tower, didn't know that Yang Rui would have shady tricks, so he stood on the main seat in high spirits and said, "You can instruct me to do it, no problem. I used to do experiments often. Pretty skilled."

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

"It's not bad. There are a few professors who teach very good lectures, and people stand and listen every time. You will also take the college entrance examination this year. If you have the opportunity, you must try it. The atmosphere of Hedong University is completely different from other schools. "Jiang De couldn't help laughing when he talked about such a proud thing in life.

In Hedong Province, his academic qualifications are considered top-notch, otherwise he would not have easily entered the Provincial Education Bureau and assumed heavy responsibilities.

"If you can break the key line, you must consider it." Yang Rui smiled, but thought in his heart: With 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.

Gossip, Yang Rui handed a round bottom flask to Jiang De, said: "Now first pipette 150 ml of suspension, then add 0.76 grams of pyrogallic acid, and then 2.58 grams of potassium hydroxide , it has already been prepared next to it... is it finished?"

"Soon." Although Yang Rui only said a few words, Jiang De was still busy. These experiments are precise experiments that are short of milligrams and milligrams, because the final extract weighs only a few grams, if some are carelessly sprinkled out, this experiment will not be done.

Moreover, without any help, using a pipette for a while, and a mechanical analytical balance for a while, it is really a big test for Jiang De, who has not done experiments for two or three years.

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

But the reality is that a novice can't beat a proficient no matter what.

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

Before waiting for a compliment, Yang Rui said: "Let's continue. Now we need to add 7ml of methanol, mix it with 55ml of distilled water and shake well, and reflux in the water bath at 90 degrees for 30 minutes. Turn on the water bath first. Also, remember to prepare tap water and water bath. When it’s done, cool it down quickly and pour it into a separatory funnel. Remember?”

Jiang De was not stupid, he reluctantly nodded and said, "I remember."

Yang Rui didn't pause,

Continued: "I will say next, at this point, we need to use petroleum ether, 40ml, and shake vigorously for 5 minutes. We don't have the corresponding equipment, so let's shake it by hand. After this step, we can continue to extract. Combined extracts."

Yang Rui didn't say what to do with the extract after he got it, because Jiang De had already started to faint, and when he mixed with distilled water, he accidentally added an extra drop.

Yang Rui immediately shouted: "Too many."

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

In any experiment with a dropper, adding more solution is the most annoying thing. If you add less, you can add more, but what if you add more? If it is a mixture of two substances, maybe you can use a lazy method to add another substance, but most of the experiments, like what they are doing now, add more than just two substances, and there is also a chemical reaction.

Yang Rui glanced at the jar, shook his head, grabbed the round-bottomed flask, emptied it all, and said, "Come again."

"This... okay." Jiang De had no choice but to listen to Yang Rui. There is only one answer to this kind of thing, no matter whether he is the section chief or the dean, he can't let the extra drop of water escape completely, and the water drop won't listen to him.

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

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

Yang Rui wouldn't let him go on easily, he kept urging him, and kept adjusting the temperature of the water bath.

When it was time for Jiang De to go to the water bath, the temperature was set incorrectly and he had to start all over again.

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

Come back two more times, it's already dark, can you still have a pleasant interview?

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

Jiang De nodded sullenly and said yes.

So Yang Rui quickly went into battle, stood opposite Jiang De, and began to operate various instruments. Not to mention his training during graduate school, even in the recent period, he has done more experiments than Jiang De, not to mention that ** has done the same coenzyme extraction experiment several times.

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.

Now he is too embarrassed to say that Yang Rui made it difficult for him, although Yang Rui was indeed making it difficult for him.

Yang Rui's expression didn't change, and he laughed in his heart.

He knows too many ways to bully newcomers in the laboratory, the simplest one, you rush him.

The more reminders, the more mistakes, the more mistakes, the more rework, the more rework, the slower the speed, and the slower the speed, the more reason to urge.

Experiments belong to a small number of academic work that can make up for one's weakness. Generally speaking, smart people are suitable for studying pure theory, only use their own brains, and don't care about others. In the 21st century, both mathematics and theoretical physics have a sense of detached metaphysics. By the time of middle school, if students haven't found the feeling of standing out from the crowd, they should almost understand that they are not material for mathematics and theoretical physics. The difficulty of experimental physics is much lower. If you are a little bit creative and have a good foundation, you can try it.

Of course, if you can't handle experimental physics and want to do academics, then you should study biology. If you have been in this industry for a long time, you can always play a role.

Domestic postgraduates who study in the second year of graduate school almost have about one year of laboratory experience, and they can do well for two years. Bully how you want to bully.

It is very rare for an undergraduate student to counterattack when he first enters the laboratory. The better the laboratory, the more this is the case. For undergraduates, the equipment is not fully recognized, so what qualifications do they have to counterattack.

Although the competition in domestic laboratories is fierce, it is not cruel after all. In the laboratories of Japan and South Korea, there are young people who are bullied and can't stand it. There are young people who jump off the building. Unlike middle and elementary schools, most of what they encounter are not violent attacks.

Doing experiments is not as fast as others, getting data is not as accurate as others, experiment design is not as good as others' creativity, more rework, waste of materials, funds overruns, progress behind schedule, dissertations cannot be passed, graduation certificates cannot be obtained, and friends are not as long. The ugliness of the teacher is not to be seen by the teacher... The more confident and inferior one is, the faster the belief will be destroyed.

In just ten minutes, Yang Rui went through the process, and then said: "Wash the extract with distilled water to neutral, and increase anhydrous sodium sulfate in proportion. Here is a formula to calculate. You will We'll discuss it later..."

Jiang De was sweating profusely, so let's see what Yang Rui did.

He wished he could hide his head under the lab table.

A dignified graduate of a key major at Hedong University, who was unable to do an experiment as a high school student, no matter how many objective reasons there are, the proud Jiang De will never forgive himself.

Ding Yaqin and the others were also dumbfounded.

Earlier, when Yang Rui was doing the experiment by himself, although it was smooth, everyone didn't think there was anything special about it, and thought that it should be like this in a normal experiment.

When Jiang De went into battle, after a comparison, several people discovered Yang Rui's speed and accuracy.

Ding Yaqin didn't know how to describe the weird atmosphere right now, but it seemed quite incorrect to say that the "communication" of West Fort Middle School was fake.

While others were struggling, Yang Rui quickly completed the most important saponification step, and then lay down on the table and began to draw the yield curve of coenzyme q10.

In this part, without Yang Rui's explanation, the content is already extremely professional.

Jiang De had finally figured out the round-bottomed flask, and Yang Rui's yield curve was all calculated.

He peeked at it twice, and didn't have the nerve to ask Yang Rui how he did the calculation. He already felt ashamed enough.

"That's about it, Section Chief Jiang checks it out." Yang Rui didn't say to ask Jiang De to continue the experiment, and the latter probably didn't want to do it either.

On the other hand, Yang Rui tried his best to choose an uncommon and complicated formula to calculate the production of coenzyme Q10 this time, which made Jiang De feel extremely uncomfortable.

He majored in chemistry. In the first three years, that is, inorganic chemistry was more on the side of biology. It was okay to read simple and easy-to-understand formulas, but he was blinded by Yang Rui's deliberately complicated formulas.

In fact, if he repeated all the experimental steps, he could still come up with something, but Yang Rui didn't give him the chance.

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

Yang Rui called people in again and started cleaning. After a while, he said: "If Section Chief Jiang is interested, he might as well measure the actual production of coenzyme q10 and compare it with the content of the suspension, so that the production rate can be seen intuitively. Has it improved?"

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

The familiar kerosene smell of petroleum ether wafted in the air, and Ding Yaqin buckled up his notebook helplessly.

"In 600 ml of suspension, 82 grams of coenzyme Q10 crystals were extracted, which is almost 13.67%..." Jiang De calculated the number and shouted habitually. He had already been assimilated by Yang Rui's laboratory discipline.

This is most common in small and tense environments.

"..." The English pronunciation is a little east of the river, repeating Jiang De's number.

Including Yang Rui, everyone turned their heads and looked at the door.

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

"Who are you two?" Jiang De shook his coat, showing the majesty of a cadre.

"This is Mr. Franky from the British Zeneca Company. He is investigating in Hedong Province. I am Lu Chengcai from China Pharmaceutical Foreign Trade Corporation. I am currently serving as Mr. Franky's translator and liaison. This is my work permit." The short translator skillfully took out a red leather notebook.

Jiang De checked it pretendingly.

Ding Yaqin's eyes lit up like a fox, and asked softly: "Mr. Franky from the British Zeneca Company? What is the purpose of your coming to West Castle Middle School?"

Lu Chengcai translated in a murmur.

Franky murmured again, and then listened to the translator: "Mr. Franky is investigating the matter of medical cooperation. In the address book, there is a paper with a contact address here. Mr. Yang Rui, is it from your company? "

"Yang Rui?"

"Yang Rui!"

"This foreigner is here to find Yang Rui!"

Several people couldn't help but read out their 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.
