"We're doing reproducibility now, so the speed will be a little faster, and if Section Chief Jiang feels unaccustomed, he can bring it up. Yang Rui's posture was very low, but what was hidden behind it was full of malice.

Jiang De, a student who had just graduated from the ivory tower, knew that Yang Rui would have a trick, and he stood on the main seat with high spirits and said, "You come to command me to do it, no problem." I used to do a lot of real yàn, and I was quite proficient. ”

"Thinking about it, the chemistry department of Hedong University seems to be particularly good, and Section Chief Jiang often does exercises?"

"It's not bad, there are a few professors who give very good lectures, and there are people standing and listening every time. You're going to take the college entrance examination this year, so if you have the chance, you must give it a try. The atmosphere at Hedong University is very different from other schools. Jiang De couldn't help but smile at the corners of his mouth when he talked about this kind of life triumphant.

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

"If you can break the key line, you must consider it. Yang Rui smiled, but thought in his heart: As far as the teaching conditions in the 80s are concerned, you say that you will do practical yàn I believe, you say you are proficient, don't underestimate the dark training in the research room.

After a few words of gossip, Yang Rui handed a round-bottomed flask to Jiang De and said, "Now pipette 150 ml of the suspension first, and then add 0." 76 g of pyrogallic acid, followed by K2 hydroxide. 58 grams, already prepared on the side...... Is it done?"

"It's coming. Don't look at Yang Rui only said a few words, Jiang De was still busy. These real yàn are all in short supply to milliliters of milligrams, because the final extract weighs only a few grams, if you sprinkle some of it out with a big grin, this real yàn will not have to be done.

Moreover, without help, one will use a pipette, and the other will use a mechanical balance to analyze the balance, which is really a big test for Jiang De, who has not been practical for two or three years.

He didn't participate when he first started, but now he participates again, and he also feels that he recalls.

But the reality is that no new hand can fight well no matter what.

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

Before waiting for a praise, Yang Rui said: "Let's continue, now we have to add 7 ml of methanol, shake well with 55 ml of distilled water, reflux in a 90-degree water bath for 30 minutes, open the water bath first, and remember to prepare tap water, cool it quickly at the end of the water bath, and pour it into the separating funnel." Can you remember?"

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

Yang Rui didn't pause, and continued: "I said next, at this point, I will use petroleum ether, 40 ml, and violently shake for 5 minutes. We don't have the corresponding instruments, so let's use our hands to shake, and after this step, we can extract continuously and merge the extracts. ”

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

Yang Rui immediately shouted: "It's too much." ”

Section Chief Jiang was excited, and couldn't help repeating: "It's too much!"

In any real yàn with a dropper, adding more solution is the most annoying thing. If it's a mixture of two substances, maybe you can use a lazy way to add another substance, but most of them are real, just like they are doing now, and what is added to it is not only two substances, but also chemical reactions.

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

"This ...... All right. Jiang De had no choice but to listen to Yang Rui. This kind of thing has such an answer, no matter whether he is the section chief or the dean, he can't let the extra drop of water run out completely, and the water droplets don't listen to him.

In order not to give the final answer to the black pot, Jiang De had no choice but to do it again obediently.

This time, his speed has accelerated, indicating that the foundation is indeed very good, and the feel has come back a little.

Yang Rui wouldn't let him do it easily, urging him vigorously, and kept adjusting the temperature of the water bath.

When Jiang De went to the water bath, the temperature was set incorrectly, and he had to start again.

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

Come back twice, it's getting dark, can you still have a pleasant interview?

Yang Rui guessed their mood, coughed and said, "Let's come together, the two of them remind each other that it is 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 appliances. Not to mention the training during his graduate studies, even in the recent past, he has done a lot more than Jiang De, not to mention that he has done the same extraction of coenzymes several times.

In terms of speed, Yang Rui is more than twice as fast as Jiang De, and the so-called mutual reminder quickly became Jiang De's desperate pursuit.

He is embarrassed to say that Yang Rui is embarrassed to embarrass himself now, although Yang Rui is indeed embarrassing him.

Yang Rui's expression remained unchanged, and he smiled in his heart.

There are too many ways for him to bully newcomers in the real yàn room, and the simplest one, you urge him.

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

Practical yàn belongs to one of the few academic works that can make up for the shortcomings of diligence. Generally speaking, smart people are suitable for pure theory, using only their own brains and not caring about anything else. In the 21st century, mathematics and theoretical physics have a sense of transcendence and metaphysics. By the time they reach middle school, if they haven't found the supreme sense of breaking the bull that stands out from the crowd, they should almost understand that they are not studying mathematics and theoretical physics. The difficulty of real physics is much lower, a little creative, and the foundation is good, so you can try it.

Of course, if you can't do physics and still want to do academics, then it's good to study biology, and you can always play a role in this industry after being in this industry for a long time.

Domestic graduate students study to the second year of graduate school, almost have about a year of real room experience, do a good job can have two years, at this time for newcomers, whether it is speed or others, it is pure and complete, in the real yàn stage, how to bully as much as you want.

If you want to say that any undergraduate student can counterattack as soon as he enters the real yàn room, this situation is really rare. The better the real room, the more so, for undergraduates, the instruments are incomplete, and what qualifications do they have to counterattack.

Although the competition in the domestic room is fierce, it is not cruel after all, in the real room in Japan and South Korea, there are young newcomers who are bullied and can't stand jumping off the building, and unlike middle schools and primary schools, most of the things they encounter are not violent attacks.

There is no such thing as someone else's fast, the number is not as accurate as someone else's, the design is not as good as someone else's creativity, there are many reworks, there are many wasted materials, the funds are overrun, the progress is behind, the thesis can't be passed, the graduation certificate can't be obtained, and the ugliness of no friends is not treated by the tutor...... The more confident and inferior one, the faster the belief will be destroyed.

In just ten minutes, Yang Rui walked through the process, and then said: "The extract is washed with distilled water to neutral, and the anhydrous sodium sulfate is increased proportionally, there is a formula to calculate, and we will discuss it later......"

Jiang De was sweating profusely, where could he care about seeing how Yang Rui got it.

His head was hidden under the real table.

A dignified graduate of Hedong University's key major, he can't be a high school student, no matter how many objective reasons there are, the proud Jiang De will not forgive himself.

Ding Yaqin and the others were also dumbfounded.

Earlier, when Yang Rui was doing real yàn by himself, although it was smooth, everyone didn't think there was anything remarkable, thinking that normal real yàn should be like this.

When Jiang De went into battle and had a comparison, 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 seemed incorrect to say that the "communication" of Xibao Middle School was fake.

While others were struggling, Yang Rui quickly completed the most important saponification step, and then lay on the table and began to draw the yield curve of coenzyme Q10.

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

Jiang De easily played the round-bottom flask, and Yang Rui's yield curve was finished.

He peeked twice, and was embarrassed to ask Yang Rui how he calculated. He already felt ashamed enough.

"That's pretty much it, Section Chief Jiang checks it. Yang Rui didn't say anything to let Jiang De continue to do it, and the latter probably didn't want to do it.

On the other hand, Yang Rui tried his best to choose a complicated formula to calculate the yield of coenzyme Q10 this time, and Jiang De was even more uncomfortable.

He studied chemistry, and in the first three years, that is, inorganic chemistry was more biological, and it was okay to look at concise and easy-to-understand formulas, but Yang Rui was blind when he deliberately made complex formulas.

In fact, if he repeated all the steps of the real yàn, he would be able to rub something out, but Yang Rui didn't give him a chance.

Section Chief Jiang twisted his hair and read Yang Rui's answer, but he still didn't have any experience.

Yang Rui called someone in again and began to clean, and after a while, he said: "If Section Chief Jiang is interested, I would like to measure the actual yield of coenzyme Q10 and compare it with the content of the suspension, and I can intuitively see whether the yield has increased." ”

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

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

"600 ml of suspension, 82 grams of CoQ10 crystals were extracted, which is almost 13. 67%......" Jiang De calculated the number, and shouted habitually, he had been a little assimilated by Yang Rui's practical room discipline.

This is the most common in small, stressful environments.

"thirteenpoint...... is a bit of Hedong English pronunciation, repeating Jiang De's number.

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

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

"Who are the two?" Jiang De shook his coat and took out the majesty of a cadre.

"This is Mr. Frankie of the British company Generica and is inspecting Hedong Province. Lu Chengcai of China Pharmaceutical Foreign Trade Company is currently working as a translator and liaison for Mr. French, and this is my work card. The short translator skillfully pulled out a red-skinned notebook.

Jiang De pretended to check it.

Ding Yaqin's eyes lit up like a fox, and he asked softly: "Mr. Frankie of the British Terricana, what is the purpose of your visit to Seaburg Middle School?"

Lu Chengcai muttered and translated.

Frankie muttered again, and then listened to the translator: "Mr. Frankie is investigating the matters of medical cooperation, and the contact address of a paper in the address book is here, 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 their names out.

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