Chapter 272

The three returned to school from work early. On the way back, they went to the chemical store to buy some materials.

In the laboratory, anzehan put the plastic particles into a crucible and boiled them with an alcohol lamp. The plastic particles melted and gave off an unpleasant burning smell.

"Wear masks and open windows for ventilation!" Song tingshen frowned. He could be poisoned if he smelled too much.

But the plastic quickly burns into black coke, which can't melt into liquid. It's impossible to pour it into the liver.

Guo Xiang was a little surprised. It turned out that this ordinary plastic didn't work. She knew what materials song tingshen used in her previous life, but she thought it was just an accidental inspiration. Other plastics could also work. Unexpectedly, it didn't work. It seems that she still has to follow the previous method.

"It seems that it can't be heated. It will burn as soon as it is heated." Anzehan said, "how can we turn them into liquids?"

"You can try acetone!" Guo Xiang said.

Song Ting took a deep look at her, "chemistry is good!"

Anzehan withdrew the fire, put the new plastic particles into a beaker, poured acetone and stirred with a glass rod. The plastic slowly began to dissolve, but it could not completely dissolve. There were many small particles, which could not reach those small veins when poured into the liver.

"Wrong material." Song tingshen said, "there should be a solubility parameter. This plastic has a corresponding solvent."

But I don't know what it is. Maybe I should ask a professional chemistry teacher.

"Mr. Song, I know a kind of plastic. Maybe I can try it." Guo Xiang said that in fact, she knows what song tingshen used in his previous life, but she can't say it directly. It won't be so obvious only after trying and making mistakes several times.

"What?" Anzehan looked at her.

"Celluloid!" Guo Xiang said that teacher song used this in his previous life. It is said that he was inspired by watching table tennis games, because Celluloid is the main material for making table tennis.

"You can try!" Song tingshen said.

"I'll buy it right away!" Anzehan is eager to try.

He went to the chemical store again, but he didn't. later, anzehan went to the table tennis factory and bought some from others.

"Why did you go so long?" Song tingshen asked.

"I went to the table tennis factory. I didn't sell this material anywhere else. People say it's a kind of synthetic plastic, which should be specially prepared." Anzehan said excitedly that he felt very useful when he could find materials.

"Then try again!" Song tingshen nodded.

Put the celluloid rubber particles into the beaker and add acetone. A miracle occurs. The rubber dissolves rapidly with the naked eye and soon dissolves into a cup of translucent and white solution.

"Succeeded!" Anzehan was very excited.

"I'll get a pair of liver." Song tingshen also had a smile on his face.

Take a pair of liver, pour out the formalin solution inside, squeeze it a little, squeeze out the solution in the blood vessels, and then the celluloid solution can completely enter the small blood vessels when it is poured in.

"Put on gloves, clamp it with pliers and be careful with your hands." Song tingshen gave Guo Xiang his liver.

"OK, Miss Song!" Guo Xiang put on gloves, clamped the portal vein of the liver with pliers, hung on a stainless steel tray and motioned to anzehan, "you can pour it in!"

"Hey!" Anzehan also wore gloves, carefully picked up the beaker and poured the solution along the hepatic portal vein.

The solution gradually entered the liver. Guo Xiang shook the liver, grabbed the vein mouth and shook it again, trying to let the solution enter all the small blood vessels, so as to pour out a complete blood vessel specimen.

When it's almost done, tie up the portal vein with a string and hang it.

"I don't know how long it will take to solidify?" Asked anzehan.

"Why don't you put it in the fridge?" Asked Guo Xiang.

In fact, she only knew the main materials used, and she didn't know the specific details. After all, she had this thing long ago when she studied medicine in future generations.

"Put the refrigerator and hang it outside. It will dry and shrink." Song tingshen said, "don't go to the hospital tomorrow morning. Come here directly. It's getting late. Let's go back and have a rest first. "

"Hey!" Anzehan responded, wrapped the liver in a plastic bag and hung it on the grid in the cold storage area of the refrigerator.

Several people went home together.

When Guo Xiang came to the school laboratory the next day, many people surrounded the door.

Su Li greeted Guo Xiang with surprise, "boss, what's the matter with you?"

They all heard about Guo Xiang's early internship. They were surprised and didn't ask her what was going on.

"Well, come to school today." Guo Xiang nodded, "what's the matter?" Guo Xiang pointed to the people around the door of the laboratory.

"I heard that the laboratory was haunted, and a liver appeared in the refrigerator where the medicine was stored. Scared the students who came to get the medicine and almost fainted. " As sully spoke, she tiptoed in.

"Ha?" Guo Xiang couldn't laugh or cry. Did he make such an Oolong?

"I think it's a prank, isn't it? Otherwise, how can a liver appear for no reason? We are medical students and can't believe in ghosts. " Sully continued.

"You'd better report to the school leader quickly?"

"Why don't you call the police directly!" A classmate said.

Guo Xiang was surprised and hurriedly shouted, "Hey, give way, give way, I know what's going on!"

Everyone turned around and looked at Guo Xiang.

"Who is she?"

"No!"

The crowd gave way. Guo Xiang went in and found a girl sitting on the ground. Her face was very white and her eyes were still full of tears. Two students were comforting her.

The door of the refrigerator was open, and half of the liver hanging inside was exposed.

"You misunderstood. This is not a prank. This is an experiment we did with Mr. Song. The liver must be kept in the refrigerator!" Guo Xiang was busy explaining.

"But I didn't finish school yesterday." The girl on the ground looked up.

When she came to get the medicine, she saw a bag hanging in the refrigerator. She was curious to open it. She didn't think it would be a pair of internal organs, which frightened her very much.

She was still a freshman and had not taken an anatomy class. She was so fierce that she was scared to death.

"We only came here last night. We are not free in the hospital during the day." Guo Xiang smiled. Unexpectedly, there was such a big oolong.

"What's going on? What are you doing here? " Behind him came song tingshen's stern voice.

"Miss Song is coming, Miss Song is coming!"

"It's really teacher song's experiment?"

"Yes, Mr. Song is an expert in liver and gall!"

Guo Xiang greeted him. "Mr. Song, it's all right. It's just that the liver is in the fridge that scares the little girl." Guo Xiang smiled.

When the girl on the ground saw the teacher coming, she blushed and stood up.

"Scared?" Teacher song looked at the girl, "it's not good to be so timid. We should exercise more courage."

"I, I'm a pharmacy major." The girl said with a red face.

"Pharmacy Majors also have anatomy classes!" Teacher song's face is very serious, "don't come to learn medicine without psychological preparation!"

The girl was bitten by such a remark and dared not say anything.
