"Yang Rui, right? Come on, let's give you a root." The aunt in the cafeteria found a long and thick fried dough stick and handed it to Yang Rui.

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

"I know, why don't I know? The photo that most people saw in the canteen the day before yesterday is yours? It's so rare that my son could grow up so carefree..." The canteen aunt soon entered the emotional mode of middle-aged and elderly women.

Yang Rui quickly thanked and gave up the window, looked at both sides, and there were indeed many friendly smiles.

In fact, I usually have many friendly smiles, but I don’t have so bright smiles or so familiar eyes.

At the beginning of 1984, Yang Rui suddenly realized that he seemed to be able to scan his face.

You can scan your face when you go to the convenience store.

When you go to the cafeteria, you can scan your face.

When you arrive in the classroom, you can also scan your face.

Especially when facing middle-aged and elderly women, handsome faces are simply unfavorable.

Being handsome can make your life more convenient! Yang Rui feels that he can simply go to advertise a plastic surgery hospital.

Also successful were Jing Yulan's residential decoration and Huarui's laboratory decoration.

The former was helped by Shi Gui to take care of it, and the area was small, and it was already in the stage of drying and preparing to move in. The latter was jointly checked by Shi Gui and Wei Zhenxue. With the continuous supply of funds, the workers finally completed the decoration and equipment installation on New Year's Day.

Yang Rui also quietly breathed a sigh of relief. It is difficult to construct in the north in winter because the weather is too cold, and building materials such as cement will degenerate, which is not conducive to long-term use. Although some materials will be used specifically in cold areas, in terms of the domestic industrial level in the early 1980s and the degree of domestic and foreign import and export troubles, instead of focusing on purchasing special materials for winter construction, it is really better to prepare materials in winter and work overtime in the spring.

The laboratory has good infrastructure level, and the instruments and equipment have also been updated. Yang Rui even bought himself a few beautiful imported pipettes.

A pipette is a very small instrument that looks and functions like a needle tube, which is used to transfer liquid from one container to another.

It sounds like this is something irrelevant, but in fact, Yang Rui’s resentment towards the pipette is hard to explain every day and night.

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

5 microliters, 10 microliters, and 20 microliters are commonly used units. In PCR experiments, 1 microliter is also often encountered.

And 1000 microliters are just one milliliter.

If it is more vivid, a drop of water will be 50 microliters.

In other words, the task of pipette is to transfer half a drop of water, one tenth of a drop of water, or even one fifty-tenth of a drop of water each time.

When Yang Rui was studying for graduate school, his supervisor was ordinary and the laboratory was ordinary, so he naturally had no money to buy a good pipette. Therefore, several scientific research dogs in the laboratory used a domestic pipette, and migrant workers handed a domestic pipette. The supervisor bought himself an imported pipette, locked it in a cabinet, and took it out only when he was doing his own experiment.

The difference between domestic pipettes and imported pipettes is usually the error of several decimal points, and sometimes there are some slight differences in the scale, and the appearance is at most ergonomic designs.

It sounds like nothing, but when a scientific research dog or a migrant worker needs to use a pipette hundreds of times a day, the difference is simply despair.

Fatigue is still endurable, but the result after fatigue is despairing.

Experiments that work hard often discuss only a few percentage points of error, and a few percentage points of error in the pipette, how can this make people feel sorry for? What should I do when I encounter this situation? Learn from seniors to fight against the sky and make their own instruments to continue doing research? Should I use my intelligence and talents to work on this kind of repetitive labor? Or do I need to fake data...

The PCR that Yang Rui is about to get involved in has higher requirements for pipettes. Sometimes, add 1 microliter or 2 microliters, and it is impossible to blow out the pipette.

After using the old gun and domestic miscellaneous pipettes for a while, Yang Rui also understood a truth: If you don’t have money, don’t study any high-tech things. Apart from being a high-priced training base, the Poor Ghost Laboratory will not have the results of returning the ticket price. It is okay for the people across the country to tighten the trouser bags to develop technology. Technology tightens the trouser bags and does experiments is a joke.

In the 1980s, domestic pipettes could not be said to have non-existent, but the word "homemade" must be added in front.

Yang Rui saw a homemade pipette in the laboratory next door, which was made of a syringe, a weighted bicycle spoke, a piece of plexiglass and a plastic liquid absorber.

Yang Rui didn't know how accurate this thing is than a pipette, but it would be too distracting to say that it is easy to use or has little error.

It can only be said that it has solved the problem of existence or not, and reduces the amount of operation of the experimenter.

Yang Rui is unwilling to enter this situation as long as he has a little chance.

It is certainly a legendary story to make research that is more perfect than a luxury laboratory with less time and harder conditions, just like a person who rarely learns has won the first place.

However, the reality is that academic masters are more hardworking, while researchers in luxury labs are more focused.

Because researchers who are not focused enough have long been eliminated by luxurious laboratories with infinite attractiveness, there are too many outstanding talents waiting in line. However, laboratories with difficult conditions can only pray except for those who are expected to be able to be included in the school occasionally.

Before Huarui's laboratory was started, Yang Rui returned to Tangjin Laboratory with his pipette.

The pipette is in the hands of a researcher, which is equivalent to the scalpel in the hands of a doctor. If you get used to it, you can't go back. Yang Rui even doubted that some people in the laboratory where he was working hard to take the doctorate exam just to get a dispensed pipette.

"Yang Rui is here?" Sun Ruyue was the first to come and was cleaning in the laboratory. When he saw Yang Rui, he greeted him obediently.

"Here you come so early?" Yang Rui took off his coat and changed into the experimental clothes.

"I'm used to it, and I can't sleep on New Year's Day, so I thought about coming to the laboratory... Yang Rui, can I help you?" Sun Ruyue mustered up the courage and made such a request.

After saying that, as if she was afraid that Yang Rui would misunderstand, Sun Ruyue hurriedly said: "I don't want the right to sign, I don't need anything. I just want to do it in practice."

Laboratory consumables have never been cheap. When Yang Rui was a graduate student, ordinary laboratories consumed thousands of yuan a day. In the 1980s, it was not far apart. The one million yuan fund applied for by Tang Ji was basically only enough for the core team. In addition to helping the core team process materials in advance and performing some scraps of materials, the funds for doing experiments themselves were usually dozens or hundreds of yuan. After 30 years, students applied for experimental funds, which were usually sent away for three to five thousand yuan.

This little money is to buy a better pipette.

Sun Ruyue is a sophomore. Although he is a little novice, his former boss didn't dare to let him practice his craftsmanship, so he could only wash bottles and read the theory of operation.

Sun Ruyue was still satisfied with this kind of life before, until she met Yang Rui.

Sun Ruyue couldn't tell how far he was from Yang Rui, and he couldn't understand those English papers. He only knew that if he didn't start now, he would definitely be pulled further and further.

"Okay." Yang Rui glanced at Sun Ruyue for a while and agreed.

"I want to do an experiment." Sun Ruyue was afraid that Yang Rui would not understand.

"Yes, start doing it, learn to deal with standard solvents and solutions..."

"Okay." Sun Ruyue was sure that Yang Rui really asked him to do the experiment, and he became 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 and train him by the way.

Compared to ordinary experimental dogs, Sun Ruyue, who has been watching for half a year, is still smart.

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

"There are inspection and evaluation teams in the afternoon. They prepare and clean the laboratory clothes. If they are dirty, they will borrow them from their classmates." Tang Ji entered the door and announced the news first.

"What are you checking?" Yang Rui asked.

"Check everything, just do your own thing. You must first go through the school's evaluation when applying for a national key laboratory. This is the first group, so don't be nervous." Tang Ji said this, picked up an empty flask and washed it in the pool.
