Chapter 301

"Yang Rui, right? Here's a long one for you. " The aunt of the canteen found a long and thick fried dough stick and handed it to Yang Rui.

"Do you know me?" Yang Rui was very surprised.

"Yes, I don't know. Isn't that your photo that most people saw the day before yesterday? It's hard to learn how to grow up well. If only my son could grow up so easily... "The aunt of the canteen soon entered the middle-aged and old women's emotion mode.

Yang Rui quickly thanks, let out the window, and then look at both sides, sure enough, a lot of friendly smile.

In fact, usually there are many friendly smile, but the smile is not so bright, not so many familiar eyes.

1984 At the beginning of the year, Yang Rui suddenly found that he seemed to be able to brush his face.

At the buffet, you can brush your face.

When you go to the canteen, you can brush your face.

In the classroom, you can also brush your face.

Especially in the face of the middle-aged and elderly women, handsome face is not conducive.

Being handsome can make your life more convenient! Yang Rui thinks that he can go to the cosmetic surgery hospital to advertise.

The same goes well with Jing Yulan's house decoration and Huarui's laboratory decoration.

The former has Shigui's help, and the area is small. It's time to air and prepare to move in. In the latter, Shi GUI and Wei zhenxue worked together to control the situation. With the continuous supply of funds, the workers finally finished the decoration and equipment installation on New Year's day.

Yang Rui was also quietly relieved. Winter in the north is not good construction, because the weather is too cold, cement and other building materials will change, not conducive to long-term use. Although some materials will be specially used in cold regions, in view of the domestic industrial level in the early 1980s and the import and export troubles at home and abroad, it is better to prepare materials in winter and work overtime in spring than to focus on purchasing special materials for winter construction.

The infrastructure level of the laboratory is good, and the instruments and equipment have also been updated. Yang Rui even bought himself some beautiful imported pipettes.

Pipette is a very small instrument, the shape and function are similar to a needle tube, used to transfer liquid from one container to another.

It sounds like an unimportant thing, but in fact, Yang Rui's resentment about the pipette can't be explained day and night.

First of all, pipettes are used in scientific research and require high accuracy, usually in microliters.

5 Microliter, 10 microliter and 20 microliter are commonly used units, and 1 microliter is often encountered in PCR experiments.

1000 microliters is a milliliter.

If the image of some words, a drop of water is 50 microliters.

In other words, the task of the pipette is to transfer half a drop of water, a tenth of a drop of water, or even a fiftieth of a drop of water at a time

When Yang Rui was a graduate student, his tutor was ordinary and his laboratory was ordinary. Naturally, he had no money to buy a good pipette. Therefore, several research dogs in the laboratory shared a domestic pipette, and the research workers had a domestic pipette, The tutor bought an imported pipette for himself, locked it in the cabinet, and used it only when he was doing experiments.

The difference between the domestic pipette and the imported pipette is usually the error of a few decimal points, sometimes there are some minor differences on the scale, and the appearance is at most some ergonomic design.

It doesn't sound like much, but when a research dog or a research migrant needs to use a pipette hundreds of times a day, the difference is almost fatal.

Fatigue can be tolerated, but the result after fatigue is despairing.

In the experiment of working hard, we often discuss the error of several percentage points, and the pipette has the error of several percentage points. How can human feelings be embarrassed? How to deal with this situation? Do you want to continue to do research with self-made instruments? Do you want to use all your intelligence in this repetitive work? Or data fraud

The PCR that Yang Rui is about to set foot in has higher requirements for pipettes. Sometimes, add 1 μ L or 2 μ L, and the pipette can't blow out.

After using old guns and homemade liquid pipettes for a period of time, Yang Rui also understood a truth. If you have no money for high-tech things, don't study them. Besides being a high-cost training base, the poor lab will not have the results worth the price. It's OK for people all over the country to tighten their trouser pockets and develop science and technology. If science and technology tighten their trouser pockets and do experiments, it's a joke.

In the 1980s, domestic pipettes did not exist, but the word "homemade" had to be added in front of them.

Yang Rui saw a self-made pipette in the laboratory next door, which was made of a syringe, a weighted bicycle spoke, a piece of plexiglass and a plastic suction nozzle.Yang Rui doesn't know how accurate this device is compared with the pipette, but it's too unconscionable to say that it's easy to use or the error is very small.

It can only be said that the problem of whether there is or not has been solved and the operator's workload has been reduced.

Yang Rui is not willing to enter this situation as long as he has a little chance.

Using less time, money and more difficult conditions to make more perfect research than luxury grade laboratory is a legend, just like people who seldom study get the first prize.

However, the reality is that Xueba is more hardworking and the researchers in luxury laboratories are more focused.

Because the researchers who are not focused enough have long been eliminated by the luxury laboratories with infinite attraction, and there are too many excellent talents waiting in line. But the laboratorial condition is arduous, in addition to expect the talent under the entrance is good enough, can only pray.

Huarui laboratory has not been started yet. At the end of the new year's Day holiday, Yang Rui went back to Tangjiang laboratory with his pipette.

If the pipette is in the hands of the researcher, it is equivalent to the scalpel in the hands of the doctor. If he is used to good things, he can't go back. Yang Rui even doubts that some people in his lab at that time worked so hard to get a dispensing pipette.

"Here comes Yang Rui?" Sun Ruyue was the first to come. He was cleaning in the laboratory. When he saw Yang Rui, he said hello.

"So early?" Yang Rui took off his coat and put on his experimental suit.

"I'm used to it. I can't sleep on New Year's day, so I want to come to the laboratory... Yang Rui, can I give you a hand?" Sun Ruyue summoned up his courage and put forward such a request.

Then, as if afraid of Yang Rui's misunderstanding, sun Ruyue said: "I don't want the right of signature. I don't need anything. I just want to operate it."

When Yang Rui was a graduate student, it was common for ordinary laboratories to consume thousands of pieces of materials a day. In fact, in the 1980s, there was no big difference. The million yuan fund Tang applied for was only enough for the core team. Besides helping the core team deal with the materials in advance and do some experiments with leftover materials, the research dogs also helped the core team, The funds for doing experiments are usually tens or hundreds of yuan, and after 30 years, students apply for experimental funds, which is usually three or five thousand sent away.

That's to buy a better pipette.

Sun Ruyue is a sophomore. Although he means to be a new star, his former boss didn't dare to let him practice. He could only wash bottles to see the theory of operation.

Sun Ruyue used to be satisfied with this life until he met Yang Rui.

Sun Ruyue couldn't tell the difference between himself and Yang Rui. He couldn't understand the English papers. He only knew that if he didn't start now, he would be pulled farther and farther away.

"All right." Yang Rui looks at sun Ruyue for a while and agrees.

"I want to do experiments." Sun Ruyue is afraid that Yang Rui doesn't understand.

"Yes, let's do it. Learn to deal with standard solvents and solutions first..."

"Good." Sun Ruyue then determined that Yang Rui really asked him to do the experiment, and the whole person was excited.

However, teaching people to do experiments is often slower than doing it himself. Yang Rui also wanted to make full use of sun Ruyue, so he trained him by the way.

Compared with ordinary experimental dogs, sun Ruyue is still smart after watching for half a year.

By the time Tang came, the research dogs had almost recovered.

"In the afternoon, there was an inspection and evaluation team. They all prepared for it. They also cleaned the experimental clothes. If they were dirty, they asked their classmates to borrow them." Tang concentrated on coming in and announcing the news first.

"What's the check?" Yang Rui asked.

"Check everything, just do your own thing. To apply for a state-level key laboratory, we have to go through the evaluation of the school first. This is the first group. Don't be nervous. " With this, Tang Jianji picked up an empty flask and washed it in the pool.
