Meet, Yanguang Qiqi

Every time he went to the laboratory, Qi You would arrive earlier, and it was the same this time.When he arrived at the laboratory, Lin Li and the others hadn't arrived yet.

Shen Jia is already doing experiments.

Seeing Qi You coming in, Shen Jia walked over, "Here we come. Lin Li and the others haven't arrived yet. I'll teach you guys later... Can you still build the device I taught you before?"

Qi You nodded.

"Okay. The reaction device for the experiment I'm going to take you to do today is the same as the one I taught you before. I will do it later, and you will build the first one. I will teach you how to use the double-row pipe to ventilate at the end."

"Okay." After speaking, Qi You didn't bother Shen Jia to do the experiment anymore, and went straight into the lounge.

When Lin Li came, Qi You was talking to Lu Jie.He came with him, as well as other members of their group. Qi You had met them a few times before and added their contact information, but they hadn't talked much and were not familiar with them.Lin Li brought several people to Shen Jia, and those who had never been here introduced themselves.

Seeing that they were all here, Shen Jia began to guide them to familiarize themselves with the environment, "This bench is my laboratory bench, you can take whatever you want from me." Then she took out a cardboard box from the cabinet below Son, "I have prepared a set of tools for you in this box, and you will use this set for experiments in the future. Wash it after use, remember to take it back after washing, and put it here. There are enough things here. If there is anything missing, Ask me first, and I’ll find it for you.” Then let one of them hold the box, “Here are gloves and masks. Before you enter the laboratory and start experiments, you must wear masks and gloves. And lab coats …Those are spare lab coats for the laboratory, each of you takes one and puts it on first.” After they finished dressing, take them to a fume hood and open the box, “I won’t introduce more about these things, you all know them .I mainly want to tell you about this." She pointed to something fixed in the fume hood, and said, "This is called a double-row tube. You will use it when you do experiments later, and it is fixed in this fume hood. Now, you don’t need to take it off when you’re done using it. But if your medicine spills into it, you still have to wash it. I’ll tell you how to use it later. You need to build a basic reaction device first…” Then she looked at Qi You, "Qi You, come here."

Qi You nodded, "Okay." So he built a reaction device with the things in the cardboard box, and stood aside after it was built.

Shen Jia watched Qi You finish setting up the device, "Everyone of you will try to build it later, and I will teach you how to use the double-pipe first." Then she demonstrated the use of the double-pipe, "Is it possible? Then Later..."

While talking, a girl next to her kicked over a cold trap filled with desiccant.

Several people were stunned.

Shen Jia glanced at it, "Fortunately it's not broken... You all should be careful not to break things later." Then he explained a few more words, and explained the order and ratio of ingredients to them, and told them again After Qi You explained a few more words, he went to his own experiments.

The five people looked at each other, and the girl who kicked over the cold trap asked, "What shall we do?"

Qi You looked at a few people, and he had the impression that Lin Li had built the device before, so he said, "Lin Li will take you to build the reaction device again. I'll go get the medicine."

Lin Li readily agreed, "Sure, you can go."

Qi You turned around and went to get the medicine.

The experiment to be done today is not much different from the experiment that Qi You did for Shen Jia before. Qi You felt that his heart was somewhat at a loss, so he relaxed a little. The medicines are all weighed.When he returned to the fume hood just now, all parts were completed.Another boy in the group took the medicines and added them to the reaction device in order.

The girl standing aside kicked the cold trap again.

Qi You saw that the cold trap was not in use, so he moved it to the side shelf.As soon as I approached the fume hood, I saw a hollow plug go towards the top of the fume hood, and then fell to the table.The girl next to her turned green with fright.

Qi You froze for a moment, "What's the situation?"

Lin Li turned around, "I don't know. I just took a breath and that's it."

Qi You walked over to have a look, "Where was this hollow plug just now?"

"Above the condenser."

Qi You checked the device again, only to find out that the switch of the double pipe was not turned on correctly, "You are equivalent to sealing the whole thing and still ventilating, the hollow plug must be pushed out... as long as no one is hurt... The ventilation must be checked in the future.”

The girl asked again, "How do you use this double pipe?"

Qi You approached the double exhaust pipe, and said while demonstrating, "When vacuuming, turn it here, so as to ensure that the system is airtight. Then turn the switch here when ventilating, and connect it to the atmosphere... ..."

The girl sighed, "Wow. Have you learned it before?"

Qi You shook his head, "No. I just heard from my senior sister too."

"Then you have a really good memory."

Lin Li curled his lips and said, "Yes. Qi You, you remember it well. I didn't remember it clearly."

Qi You smiled and said nothing.

After the device was set up again, Qi You checked it again, "Okay, open the nitrogen valve."

After exhausting the air three times, they ventilated again, Qi You said, "This time we can ventilate for a while to close all the vents of the whole device, or..." Qi You looked at the rubber tube on one side, "Why is this a ball?"

A few people followed Qi You's line of sight, and the rubber tube for ventilation seemed to be blocked, and the bent part bulged up like a blown balloon, because the position was just between the steel cylinder and the fume hood, and it was blocked just now. .

Qi You hurriedly turned off the air valve, and said while closing it, "Our experiment today is really not going well."

A few people also laughed and complained a few words.

Qi You touched the rubber tube, "It's stained with oil, it might have stuck just now. I'll find another one." Then he turned around and went to the fume hood next to him to get a new rubber tube, and tried the rubber tube first. Ventilation, and then put it on.

Several people tossed and tossed for a while before finally setting up the device and completing the experiment according to the operation steps.

After the experiment was finished, Shen Jia told them again, "What you are going to do in the near future is this experiment. I don't recommend that you come together with several people every time. You should divide the five of you into groups. Divide into two groups. Lin Li and Qi You separated, because the two of you are familiar with the laboratory, and then the remaining three separated. You arrange it yourself. Okay." After speaking, he explained a few more words, and let the five people leave.

The five people walked out, talking about grouping.

Qi You felt a little embarrassed, because apart from Lin Li, he didn't know the other three people, but Shen Jia made them separate.

Qi You pursed his lips and did not speak.

Lin Li looked at Qi You, and then said to the only boy among the remaining three, "Cao Yu, come with Qi You."

The girl who just kicked over the cold trap twice joked, "Why, you are going to take us two girls by yourself."

Qi You knew that Lin Li was afraid that he would be more uncomfortable with the girls, so he said, "That's good, we two boys should have fewer people, and if you have girls, you can have more people and coordinate."

Cao Yu had no objection to this, so he patted Qi You on the shoulder, "I'll rely on you from now on."

Qi You smiled, "That is, I will cover you from now on."

Several people chatted about the allocation of experiment time, and they dispersed when they were about to arrive at the dormitory.
