"Yang Rui, right? Come, give you the root growth. Pen ~ Fun ~ Pavilion www.biquge.info" The aunt in the canteen found a long and thick fritter and handed it to Yang Rui.

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

"Know, why don't you know, isn't the photo that the most people see in the cafeteria the day before yesterday you......rs?

Yang Rui hurriedly thanked and let go of the window, and then looked at both sides, and sure enough, there were many more friendly smiles.

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

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

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

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

When you get to the classroom, you can also brush your face.

Especially in the face of middle-aged and elderly women, the handsome face is simply invincible.

Becoming handsome can make your life more convenient! Yang Rui felt that he could simply advertise for plastic surgery hospitals.

Also going smoothly were the residential renovation of Jing Yulan and the renovation of Sinovel's laboratory.

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 is Shi Gui and Wei Zhenxue teamed up to check, and with a steady supply of funds, the workers finally rushed to finish the decoration and equipment installation on 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 there will be some materials dedicated to cold regions, in the early 80s, the level of domestic industry, as well as the degree of import and export trouble at home and abroad, instead of focusing on the purchase of special materials for winter construction, it is really better to prepare materials in winter and work overtime in spring.

The infrastructure of the laboratory is good, and the instruments and equipment have 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 syringe and is used to transfer liquids from one container to another.

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

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

5 μl, 10 μl, 20 μl are commonly used units, and in PCR experiments, 1 μl is also commonly encountered.

And 1000 microliters is one milliliter.

If it is more figurative, one drop of water is 50 microliters.

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

When Yang Rui was in graduate school, his mentor was ordinary, and the laboratory was ordinary, so naturally he didn't have the money to buy a good pipette, so several scientific research dogs in the laboratory shared a domestic pipette, and the scientific research migrant workers had a domestic pipette, and the tutor bought himself an imported pipette, locked it in the cabinet, and only took it out when he was doing experiments.

The difference between domestic pipettes and imported pipettes is usually an error of a few decimal places, and sometimes there are some small differences in scales, and the shape is at most ergonomic design.

It may not sound like much, but when a research dog or a research migrant worker needs to use a pipette hundreds of times a day, the difference is almost deathly.

Fatigue can be endured, but the result of fatigue is despairing.

Experiments that are done desperately often only discuss an error of a few percentage points, and pipettes have an error of a few percentage points, so how can this make people embarrassed? What should we do when we encounter such a situation? Learn from our predecessors and continue to do research with self-made instruments? Should we use all our ingenuity and wisdom in this kind of repetitive labor? Or should we falsify 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 if you can't blow it out in the pipette, you can't blow it out.

After using old guns and domestic miscellaneous pipettes for a period of time, Yang Rui also understood a truth, all high-tech things, don't study them if you don't have money, and the poor ghost laboratory will not have results worth the price except for the high-priced training base. It is okay for the people of the whole country to tighten their trouser pockets and develop science and technology, but it is a joke for science and technology to tighten their trouser pockets and conduct experiments.

And in the 80s, there was no such thing as a domestic pipette, which could not be said to be non-existent, but the word "homemade" had to be added in front of it.

In the lab next door, Yang Rui saw a homemade pipette, made of a syringe, a weighted bicycle spoke, a piece of plexiglass, and a plastic pipette nozzle.

Yang Rui doesn't know how accurate this thing is compared to a pipette, but it would be too unconscionable to say that it is easy to use or has a small error.

It can only be said that it solves the problem of existence and absence, and reduces the amount of operation of the experimenter.

As long as Yang Rui has the slightest opportunity, he is unwilling to enter this situation.

It is certainly a legendary story to make a more perfect research than a luxury laboratory with less time and more difficult conditions, as if a person who rarely learns gets the first place.

However, the reality is often that the top students are harder, while the researchers in the luxury-level labs are more focused.

Because researchers who are not focused enough have long been eliminated by the infinitely attractive luxury laboratories, there are too many talented people waiting in line. And in the difficult conditions of the laboratory, in addition to hoping that the occasional person who is included in the door will be good enough, it can only pray.

The Sinovel laboratory has not yet started, and after the New Year's Day holiday, Yang Rui returned to the Tang Centralized Laboratory with his pipette.

The pipette is in the hands of the researcher, which is equivalent to the scalpel in the hands of the doctor, and if you get used to it, you can't go back, and Yang Rui even doubts that some people in the laboratory where he was back then, who worked so hard, were just to get a pipette.

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

"Came so early?" Yang Rui took off his coat and changed into a lab coat.

"I'm used to it, and 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 plucked up his courage and made such a request.

After speaking, as if he was afraid that Yang Rui would misunderstand, Sun Ruyue hurriedly said: "I don't want the right of signature, I don't need anything, I just want to operate it in real combat." ”

The consumables in the laboratory have never been cheap, when Yang Rui was a graduate student, it was common for ordinary laboratories to consume thousands of materials a day, in the 80s, in fact, it was not far behind, Tang concentrated on applying for millions of yuan of funds, basically only enough for the core team to use, in addition to helping the core team to process materials in advance, do some leftover experiments, their own experiments are usually tens of hundreds of yuan, and after 30 years, students apply for experimental funds, usually three or five thousand sent away.

This money is to buy a better pipette.

Sun Ruyue is a sophomore, although he is a bit of a new star, and the previous small boss did not dare to let him practice his skills, so he could only wash the bottle and watch the operation theory.

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, and he couldn't read those English papers. He only knew that if he didn't start now, he would definitely be pulled farther and farther away.

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

"I wanted to experiment. Sun Ruyue was afraid that Yang Rui would not understand.

"Yes, let's get started, learn to handle standard solvents and solutions first......"

"Good. Only then did Sun Ruyue determine that Yang Rui really asked him to do the experiment, and the whole person became excited.

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

Compared with ordinary experimental rookie dogs, Sun Ruyue, who has watched it for half a year, is quite clever.

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

"In the afternoon, there was an inspection and evaluation team, and they all prepared it, and the lab clothes were cleaned, and if they were dirty, they asked their classmates to borrow them. Tang concentrated on entering the door and announced the news first.

"What is it to check?" Yang Rui asked.

"Check everything, you just do your own thing. To apply for a national key laboratory, you must first go through the evaluation of the school, which is the first group, so there is no need to be nervous. Tang Zhong said this, picked up an empty flask, and washed it in the pool.
