I Have a Research Support System

At 12:50 noon, Xu Qiu received a call with the note Microwave Reactor.

Hello.

Hello, is this Wei Xingsi's research group?

That's right, you are the engineers who installed the microwave reactor, are you at school now?

Yes, our vehicle has now arrived at the main entrance of the Zhangjiang Campus of Shanghai Comprehensive University, but was stopped by the security guards at the security office, saying that we must apply for permission to enter.

Well, I see. I'll deal with it right away. What's your license plate number?

Hu A...

Okay, wait until you have the permission to drive directly to the downstairs of the microelectronics, and then contact me.

Okay, excuse me, teacher.

Foreign vehicles need to apply for a temporary permit if they want to enter or leave the campus. The normal process is for the teacher to call the security office and report their work number and license plate number for filing.

Usually, this kind of matter is left to Mr. Wei to handle, but now that Mr. Wei is not around, the students have to do it themselves.

Xu Qiu asked her senior to confirm Teacher Wei's work number, 32101, and then found the extension number of the Zhangjiang Campus Security Office on the school website, and dialed it.

A loud voice came: Hello, this is the Zhangjiang Security Office.

Xu Qiu adjusted his voice, trying to appear more mature, imitating Teacher Wei's usual speech: Well, there is a car coming into the campus now, the license plate number is Shanghai A..., and my job number is 32101.

Okay. The other party replied bluntly, without seeming suspicious, but Xu Qiu quickly hung up the phone and breathed a sigh of relief.

Brother, you're pretty good at learning. Han Jiaying smiled narrowly.

Xu Qiu shook his head, it was the first time he did such a thing, he was really not used to it, he felt a little guilty.

Five minutes later, Xu Qiu received another call from the Microwave Reactor and learned that the other party had arrived downstairs, so he took the elevator to the first floor and opened the door for them.

Similar to the purchase of Qiu Heming to deliver TRPL instruments last time, this time it was also a middle-aged engineer with two younger brothers, all male, who drove a minivan and parked on the side of the road.

Speaking of which, almost all the sales related to instruments and optoelectronic materials that Xu Qiu came into contact with in the laboratory were men, and there was no girl in my impression. Maybe this industry is a place where engineering men gather.

The lead engineer directed the two younger brothers to carry the equipment, turned around and smiled friendlyly at Xu Qiu, stretched out his hand, shook hands, and asked, What's your name?

Seeing that he was so polite, Xu Qiu responded politely: Mian's surname is Xu, what's your name?

The other party said: Mr. Xu, hello, just call me Liu Gong.

Xu Qiu nodded. He probably understood Liu Gong's thoughts. When dealing with people in scientific research institutions, if you don't know the identity of others, it is definitely right to call him a teacher.

However, he had no intention of correcting it, so he walked directly into the building and pointed the way to the two guys carrying the equipment, There is an elevator here, and our laboratory is on the fifth floor.

A group of four people took the equipment and took the elevator to the fifth floor.

Han Jiaying and Chen Wanqing got the news before and waited at the door of the laboratory early.

Everyone entered the laboratory.

Hey! Liu Gong said with emotion: Mr. Xu, your laboratory is quite big.

Yeah, it's about 200 square meters. Xu Qiu agreed, then looked at the school girl beside her who seemed to be holding back a smile, and shrugged helplessly.

Not bad, and the laboratory is quite clean, and the smell of organic solvents is not strong. Liu Gong looked around and said, By the way, where do you plan to store the instrument? It's best to find a fume hood.

Let's put it in this fume hood. Xu Qiu pointed to his own fume hood, which had already been cleaned up.

This is the result of his discussions with his seniors and juniors. Relatively speaking, he does organic synthesis experiments less frequently. There are six fume hoods, one for inorganic, one for rotary evaporation, and one for liquid chromatography. , these three couldn't move, so he could only vacate his fume hood first.

Anyway, Xu Qiu has experiments to do in the future, so he just needs to get a seat with his junior or senior sister, and it won't have much impact.

Liu Gong waved to the two younger brothers, and the two quickly unpacked and put the microwave reactor into the fume hood. Unlike TRPL, which needs on-site installation this time, the microwave reactor is an all-in-one machine, but there are many accessories.

After installing the instrument and plugging in the power, Mr. Liu started debugging, and at the same time introduced to Xu Qiu and others:

Mr. Xu, our machine is a focused single-mode microwave synthesis host. It adopts CEM's patented auto-focus coupling ring microwave technology, which can continuously output microwaves and ensure that the microwave absorption of all samples is maximized. It can perform high-pressure sealed reactions. Reaction with normal pressure reflux, the maximum reaction volume is 125 ml...

The instrument includes an infrared temperature controller, a pressure controller, a display and a keypad, a built-in electromagnetic stirring system, a polymer-lined chamber, and a microwave attenuator...

There are computer ports, network ports, two USB ports...

Xu Qiu interrupted: Does this need to be connected to a computer?

Yes, after connecting to the computer, you can control the heating program and reaction time. Liu Gong looked at the fume hood of the liquid chromatograph, and said, This should be a liquid chromatograph, and you can use its computer to control the microwave. Reactor equipment, just not far away, how about it?

Okay, please trouble Mr. Liu. Xu Qiu thought for a while, nodded and agreed, TRPL was in a special situation before, it would be a waste to buy a computer this time.

No trouble, this is what we should do, Liu Gong said politely, and then he took out a CD from his briefcase and handed it to one of the younger brothers, Xiao Zhang, go and install the software.

Xiao Zhang was about to press the power button of the computer when Chen Wanqing suddenly said, Wait a minute. She handed Xiao Zhang a pack of disposable latex gloves, Wear gloves to operate, and take precautions in the organic laboratory.

Thank you. Xiao Zhang was stunned for a moment, unpacked the glove, put on a glove, and operated carefully.

It will take some time for him to install the software. Mr. Xu, let's first check whether the components of the instrument are complete, and then sign the acceptance form. Mr. Liu took out a document in duplicate on A4 paper from his briefcase, and handed it to the To Xu Qiu.

Xu Qiu took it over and looked at it, and there was a long list of parts on the list.

He jumped directly to the bottom. The original price was 45,800 U.S. dollars, and the discounted price was 34,550 U.S. dollars. According to the current exchange rate, he converted it in his mind, and it was about 200,000 yuan, less than 300,000 yuan.

Liu Gong, start checking.

Okay, Teacher Xu.

10ml Pressure Reaction Tube Kit, includes 100 10ml Pressure Reaction Tubes, 100 IntelliVent Sealing Caps, 100 Reaction Safety Films, 50 3mm Stir Bars.

Xu Qiu picked up the first package of parts and began to check. He mainly checked whether several parts were in order, and he was not so bored as to carefully count whether the number of test tubes was 100.

Thinking about it, it is impossible for them to falsify the quantity. The main fear is that there will be mistakes and omissions. For example, there are only test tubes, no sealing caps, or no safety film, which will be embarrassing.

No problem, next.

35ml pressure reaction test tube package, a total of 25 sets of 35ml pressure reaction test tubes, sealing caps, safety film, and 5 stirring bars.

Well, no problem.

One 10ml high pressure attenuator, one 35ml high pressure attenuator and one normal pressure attenuator.

These are fine.

The electronic version of the operation manual, this little sheet will be installed directly into the computer.

One condenser support rod, one condensation clip, one overflow cup.

Well, no problem.

Mr. Xu, you sign here.

Xu Qiu confirmed that there were no missing parts, so he directly signed his name on the two acceptance sheets, then took out his mobile phone to take a few photos of the instrument and parts, and sent them to Teacher Wei.

At this time, Xiao Zhang's software had been installed, and Xu Qiu and Liu Gong walked over together.

This time it is not like before TRPL gave a temporary activation code, which is directly used permanently.

Liu Gong’s operating software demonstrates the operation of the instrument using 10ml, 35ml pressure reaction test tubes and a common 24-mouth 50ml flask respectively. The solvent used is ethyl acetate solvent with low toxicity. The main tests are heating function, condensation Whether the reflow function and software control are normal.

As for the specific reaction conditions after switching to a microwave reactor, Xu Qiu and the others will have to figure it out by themselves in the future.

Xu Qiu silently copied Liu Gong's skill, microwave reactor, proficiency level 5 30%, GET.

The experimental operation method is not difficult and can be roughly divided into three steps.

First, add the solvent to a 10 or 35 ml pressure reaction test tube, install a safety film, cover the sealing cap, and place it in the card slot inside the microwave reactor.

Then, in the computer software, create a new method, name it, set the temperature and time, and save the method.

Finally, in the area where the sample rack is displayed, find the position where the reaction test tube is placed, right-click, load the method, and the corresponding reaction test tube will start to execute according to the method.

If two kinds of pressure reaction test tubes with original specifications are used for the synthesis reaction, it can withstand high pressure, and the reaction temperature can greatly exceed the boiling point of the reaction solvent;

However, if an ordinary flask is used, the reaction conditions must be consistent with normal conditions, and high-pressure reactions cannot be performed.

After adjusting the instrument, Liu Gong shook hands with Xu Qiu again and said, If you have any questions, you can contact us in time.

Okay, thank you for your hard work today, Xu Qiu said politely, saw the senior sister next to him, and said in a strange way: Xiao Chen, go see Liu Gong off.

No, no. Liu Gong hurriedly waved his hand.

Chen Wanqing was stunned for a moment, and after realizing it, she gave Xu Qiu a blank look, then turned her head and put on a smiling face: Gong Liu, this way please.

Xu Qiu patted his forehead with his left hand, what did I say to senior sister just now...

Forget it, let's go back to the office and wash our hands first. Mr. Liu doesn't even wear gloves when operating instruments.
