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

"You know me?" Yang Rui was very surprised.

"I know, why don't I know, isn't the photo that most people saw in the cafeteria the day before yesterday belonged to you? How rare is it to be handsome after studying well, if only my son can grow up so worry-free..." The aunt in the cafeteria was very happy Quickly enter the emotion mode of middle-aged and elderly women.

Yang Rui quickly thanked him for letting him out of the window, and then looked at the two sides, and there were many friendly smiles.

In fact, there are many friendly smiles at ordinary times, but the smiles are not so bright, and there are not so many familiar eyes.

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

Go to the canteen, you can brush your face.

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

In the classroom, you can also brush your face.

Especially in the face of middle-aged and elderly women, a handsome face is almost unfavorable.

Being handsome can make your life more convenient! Yang Rui felt that he could advertise for a plastic surgery hospital.

The renovation of Jing Yulan's house and the renovation of Huarui's laboratory also went smoothly.

The former has Shi Gui to help take care of it, and the area is small, and it has reached 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 finished the decoration and equipment installation in time for New Year's Day.

Yang Rui also quietly breathed a sigh of relief. Winter in the north is not good for construction, because the weather is too cold, cement and other building materials will be denatured, which is not conducive to long-term use. Although some materials are specially used in cold regions, considering the domestic industrial level in the early 1980s and the troublesome import and export at home and abroad, it is better to prepare materials in winter than to focus on purchasing special materials for winter construction. Work overtime in spring.

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

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

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

First of all, pipettes are used in scientific research, requiring high precision, and the unit is usually microliters.

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

And 1000 microliters is one milliliter.

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

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

When Yang Rui was in graduate school, his supervisor was average and his laboratory was average, so he naturally had no money to buy a good pipette. Therefore, several scientific research dogs in the laboratory shared a domestic pipette, and the scientific research migrant worker had a domestic pipette. Pipette, and the instructor bought an imported pipette for himself, locked it in the cabinet, and only used it when he was doing experiments.

The difference between domestic pipettes and imported pipettes is usually an error of a few decimal points.

Sometimes there are some small differences on the scale, and the shape is at most some ergonomic design.

It may sound like nothing, but when a research dog or a research worker needs to use pipettes hundreds of times a day, this difference is simply frustrating.

Fatigue can be endured, but the result after fatigue is hopeless.

In the experiments that are done desperately, the error of a few percentage points is often discussed, and the pipette has an error of a few percentage points. How embarrassing is this? What should I do in this situation? Learn from the old predecessors to fight against the sky and make homemade instruments to continue research? Do you want to use your ingenuity on this repetitive labor? Or the data is falsified...

The pipette that Yang Rui is about to set foot in has higher requirements for pipettes, sometimes adding 1 microliter or 2 microliters, if the pipette does not blow out, it will not blow out.

After using old guns and domestic miscellaneous brand pipettes for a while, Yang Rui also understood a truth. If you don’t have money, don’t study any high-tech gadgets. Apart from being a high-priced training base, the Poor Ghost Laboratory will not have Results worth the fare. It is okay for people across the country to tighten their trouser pockets to develop science and technology, but it is a joke to tighten their trouser pockets to conduct experiments.

In the 1980s, it cannot be said that domestic pipettes did not exist, but the word "self-made" must be added in front.

Yang Rui saw a self-made pipette in the laboratory next door, made of a syringe, a heavy bicycle spoke, a piece of plexiglass and a plastic nozzle.

Yang Rui doesn't know how accurate this thing is compared to a pipette, but to say it's easy to use or the error is very small, it would be too ignorant of conscience.

It can only be said that it solves the problem of availability and reduces the workload of the experimenters a little.

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

It is certainly a legendary story to use less time and funds, and more difficult conditions, to make research that is more perfect than that of a luxury laboratory, as if a person who rarely learns has won the first place.

However, the reality is often that top students work harder, while researchers in luxury laboratories are more dedicated.

Researchers who are not dedicated enough have long been eliminated by the infinitely attractive luxury laboratories, and there are too many outstanding talents waiting in line. Laboratories with harsh conditions can only hope that the occasional recruits will be good enough, and they can only pray.

The Huarui laboratory has not yet started. After the New Year's Day holiday, Yang Rui returned to Tang's concentrated laboratory with his pipette.

A pipette in the hands of a researcher is like a scalpel in the hands of a doctor. Once you get used to it, you can't go back. Yang Rui even doubts that some people in the laboratory where he worked so hard Cobb, just to get a set of issued pipettes.

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

"Are you here so early?" Yang Rui took off his coat and put on a lab coat.

"I'm used to it. I can't sleep on New Year's Day, so I just want to come to the laboratory...Yang Rui, can I help you?" Sun Ruyue summoned up his courage and made such a request.

After finishing speaking, Sun Ruyue seemed to be afraid that Yang Rui would misunderstand, and quickly said, "I don't want the right of authorship, I don't need anything, I just want to practice it in actual combat."

Laboratory consumables have never been cheap. When Yang Rui was a graduate student, it was not uncommon for an ordinary laboratory to consume thousands of yuan of materials a day. In the 1980s, it was not far behind. Basically, it is only enough for the core team. In addition to helping the core team process materials in advance and doing experiments on leftover materials, the research dogs usually spend tens of hundreds of dollars on their own experiments. After 30 years, students apply for experimental funds. Usually that is three to five thousand sent away.

For this little money, you can buy a better pipette.

Sun Ruyue is only a sophomore. Although he looks like a new star, his former boss didn't dare to let him practice his skills, so he could only wash the bottle and look at the theory of operation.

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

Sun Ruyue couldn't tell how far he was from Yang Rui, 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 away.

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

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

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

"Okay." Only then did Sun Ruyue confirm that Yang Rui really asked him to do the experiment, and his whole body became excited.

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

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

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

"There will be an inspection and evaluation team in the afternoon, so prepare everything and clean the lab coats. If you get dirty, you can borrow from your classmates." Tang concentrated in the door and announced the news first.

"What is the inspection?" Yang Rui asked.

"Check everything, just do your own thing. Applying for a national key laboratory must first go through the school's evaluation. This is the first group, so don't be nervous." Tang concentrated and picked up an empty amplifier flask, rinsed in the sink.
