Chapter 296: Pipettes

"Yang Rui, right? Come, give you the root growth. The aunt in the cafeteria 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 smooth are the residential decoration of Jing Yulan, and the decoration of the real yàn room of Huarui.

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, given the domestic industrial level in the early 80s, as well as the import and export troubles at home and abroad, it is better to prepare materials in winter and work overtime in the spring than to focus on purchasing special materials for winter construction.

The infrastructure level of the real yàn room is good, 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 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 microliters, 10 microliters, 20 microliters are commonly used units, and 1 microliter is also commonly encountered in PCR.

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 tutor was ordinary, and he naturally had no money to buy a good pipette, so several scientific research dogs in the real room 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 it himself.

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.

What should we do when we encounter such a situation? Learn from our predecessors and make our own instruments to continue our research? Should we use all our ingenuity and talents for this kind of repetitive labor? Or should we make a few percent of the calculations......

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, if you don't have money, don't study them, and the poor ghost room will not be worth the price of the results 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, and it is a joke for science and technology to tighten their trouser pockets and make it real.

And in the 80s, domestic pipettes could not be said to be insignificant, but the word "self-made" had to be added in front.

Yang Rui saw a homemade pipette in the next room, 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 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 real yàn personnel a little.

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 study than a luxurious real yàn room with less time and more difficult conditions, as if a person who rarely studied won the first place.

However, the reality is often that the top students are harder, while the researchers in the luxurious real room are more focused.

Because the researchers who are not focused enough have long been eliminated by the luxurious real room with infinite attraction, there are too many excellent talents waiting in line. And in the difficult conditions, the real yàn room can only pray except for the hope that the people who occasionally join the door will be good enough.

The Huarui room has not yet been activated, and after the New Year's Day holiday, Yang Rui returned to the Tang Concentration room with his pipette.

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

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

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

"I'm used to it, and I can't sleep on New Year's Day, so I want to come to the real room...... 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 real room have never been cheap, when Yang Rui was a graduate student, the ordinary real room consumed thousands of yuan of materials a day, in the 80s, in fact, it was not far behind, Tang concentrated on the application of millions of yuan of funds, basically only enough for the core team to use, in addition to helping the core team to deal with materials in advance, to make some scraps of real materials, their own real funds are usually tens of hundreds of yuan, and after 30 years, students apply for real 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 want to be real. 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 be real, and the whole person became excited.

However, teaching others to do practical yàn is often slower than doing it himself, and Yang Rui also wants to make full use of Sun Ruyue, so he trains him by the way.

Compared with ordinary real 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 their state.

"In the afternoon, there is an inspection and evaluation team, all of them are ready, the real clothes are also clean, and the dirty ones on the body are borrowed from classmates. 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 the national key practical room, you must first go through the evaluation of the school, this 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.
