Heating had begun to be provided in the dormitory, and it was getting colder outside, Lu Tao sat at the yellowed desk, looking at a few products that Senior Brother Dong had written on paper.

There are several chemical reagents, with specific CAS numbers indicated, as well as consumables such as centrifuge tubes, syringe filters, and so on.

Don't look at a few things that don't seem to be worth much, but he can understand that if these reagents are not general-purpose reagents, then the price will be high.

In his previous life, when he was doing experiments, he often used it, and it was all measured in milligrams and milliliters. For example, some imported reagents, don't look at the packaging is only written 50 mg, in fact, when you ask the price, the expensive ones are tens of thousands, and the cheap ones have to be hundreds, and the gap is very large.

Fortunately, I had already thought of this when I contacted the manufacturer before, so when I contacted him, I asked each manufacturer to send the catalog and price list, and also let the discount authority be indicated there. Otherwise, sometimes the customer urgently needs something, and he spends too much time back and forth when he calls to ask the manufacturer, so it is better to keep the approximate price of some commonly used products in mind, and to quote at any time.

Take out this thick catalog and price list and compare them one by one.

Slightly disappointed, a few reagents were not as valuable as he imagined, adding up to only more than 2,000 yuan. Even if you count those consumables, the total price is more than 4800.

"It's only over 4,000. Looking at the form, he stood up and stretched. I roughly calculated in my mind, according to the 30% profit of the reagent, it is more than 600 yuan, and the profit of consumables is lower, only 20%, that is, more than 400, which is equivalent to the overall gross profit of this list is about 1000 yuan, except for the negotiated share with the manufacturer, in fact, what he can get is only more than 400 yuan.

At that time, I talked to the manufacturer about 55 shares, but what I just calculated, after all, it was only a gross profit, and I had to remove various costs on the company's side, such as value-added tax, corporate income tax, transportation costs, etc., and it was estimated that it was just that.

"The phone bill cost 150, and this list is only so little. He thought about it, a little dissatisfied.

"Lu Tao, we haven't been outside for a long time. Just when he was still in a bad mood, Li Hong lay on the bed and said.

"Jubei, where are you going to eat this time?" Rong Chao flipped through the comic book "The Legend of Double Dragons of the Tang Dynasty" rented from the bookstore.

Zhang Jian, who was in the lower bunk of Rongchao, also came back during this time, and when he heard about the party, he suddenly became interested, put down the martial arts novel in his hand, and sat up.

"I couldn't go to that place last time, it's rubbish, and what kind of food is there. "The mouth is dissatisfied.

"If you have money, then you can tell me a place, big guy AA, eat a good meal. “

"I'm a rich fart, and recently my parents have been stuck to death, and they give me 250 yuan a month for living expenses. As soon as he mentioned this, Zhang Jian couldn't help but be angry, and glanced at Li Hong.

"I think you're a 250. Li Hong didn't care, and scolded directly.

Listening to the conversation between several people, Lu Tao was directly relieved that he only earned a few hundred yuan this time.

Yes, Zhang Jian's parents are from the local court, his living expenses are only more than 200 a month, and he and several other roommates are a little more than 100 a month.

This is just a laboratory, there are so many laboratories in the whole school, as long as you work hard, run well, and make relationships, even if it is only 10 laboratories to buy from your side, it will be at least a few thousand yuan a month. Besides, these are all consumables, and what about the equipment?

You must know that a professor's annual scientific research funds are as small as tens of thousands of yuan, but as many as hundreds of thousands, or millions, even if he does some of them, it is not a small amount.

Thinking of this, he couldn't help but laugh.

"Lu Tao, you say, what are we going to eat this time?" Several people didn't discuss the reason, and asked him directly.

Lu Tao looked at a bulging white bag hanging outside the window, turned his head and smiled: "Why don't we make mutton in the dormitory?"

"Shabu mutton?" several people's eyes focused directly on his face.

"You can figure it out, how can the dormitory make mutton?"

"That's a good idea, hahaha, it's too cold outside, it's better to drink some two-pot head of mutton in the dormitory, and then lie on the bed and blow it casually. “

Thinking of this first list, although the money was a little less, Lu Tao was still very happy, and couldn't help but say: "It's not simple, doesn't Brother Long have a rice cooker?"

The brother Long in Lu Tao's mouth, named Huang Xinglong, is a local rural person. He is the eldest in the dormitory, and he is also the eldest son in the family, and there are two younger sisters and a younger brother below, and the family conditions are the worst of several people, so he basically does not go to the cafeteria to eat, and brings some pancakes made of cornmeal from home, steamed buns, pickles, green onions, etc., to cook in the dormitory.

Hanging from the window outside is what he brought.

No way, the smell of green onions and pickles is heavy, if you put it in the dormitory, basically the whole room is full of smell, and now the weather is starting to get colder, you can avoid mice and smells when you put it outside, and it is better than putting it in a heated dormitory to keep it fresh.

Li Hong looked at the small rice cooker on the windowsill and said, "Just this big pot, enough for a few of us?"

The reason why Lu Tao said such a proposal was actually recalling that when he was in college in his previous life, several people did this.

I still remember that at that time, a few people thought it was too cold to go out to eat, so one of them scraped together some money and went directly to the outside market to buy a few catties of mutton, a few catties of chrysanthemum, plus a sauce packet, and ate mutton directly in the dormitory.

Since the pot is usually used by Brother Long alone, he bought a smaller one, which is not much bigger than the bowl.

Thinking of that scene, Lu Tao felt a little funny.

At that time, except for Brother Long, when he went home, there were five people in the dormitory, the chopsticks with chopsticks in his right hand, the fork with the fork, and a rice bowl, pot lid, and lunch box lid in his left hand.

Originally, the power was small, and it was hard to wait for the water to boil, and a few pieces of mutton were put in, and I had to wait for a while, and it was finally cooked, and a few chopsticks were clamped, and it was gone.

That's not all, if someone puts some chrysanthemum in it, the whole pot will be invisible.

Drinking a two-dollar vial of Red Star Erguotou, waiting for the mutton shabu, while worrying about the electricity tripping in the dormitory, the gods of the sky and the north of the sea are blowing. Thinking about such a day, although it is a little ridiculous, looking at the smiles of several brothers in the dormitory, Lu Tao feels so warm and simple.

"Then let's shabu mutton, 10 yuan per person is about the same, and when the time comes, buy less mutton and more chrysanthemum. “
