Chapter 244: Teacher Xu

"I have a scientific research support system novel ( to find the latest chapter!
At 12:50 noon, Xu Qiu received a call remarked as "microwave reactor".
"Hello."
"Hello, is this Wei Xingsi's research group?"
"Yes, you are the engineers who installed the microwave reactor, are you at school now?"
"Yes, our vehicle has now reached the main entrance of the Zhangjiang campus of the Magic City University, but it was stopped by the security guard at the Security Office, saying that it would have to apply for passage to enter."
"Well, I see, I will deal with it right away, what is your license plate number?"
"Shanghai A..."
"Okay, when you have access rights, drive directly to the downstairs of Microelectronics, and then contact me."
"Okay, trouble teacher."
If foreign vehicles want to enter or leave the campus, they need to apply for a temporary pass. The normal process is for the teacher to call the security department and report their job number and license plate number for filing.
Normally, this kind of matter is handled by Teacher Wei, but now that Teacher Wei is away, the students have to take care of themselves.
Xu Qiu asked the senior sister 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 Zhang Jiang Security Office."
Xu Qiu adjusted his voice, trying to appear more mature, imitating Teacher Wei's usual words: "Well, there is a car going to campus now, the license plate number is Shanghai A..., my work number is 32101."
"Okay." The other party replied altogether, as if there was no doubt, Xu Qiu quickly hung up the phone and breathed a sigh of relief.
"Brother, I learned a lot like this." Han Jiaying smiled narrowly.
Xu Qiu shook his head, and when he returned to doing this kind of thing, he was really not used to it, and felt a little guilty.
Five minutes later, Xu Qiu received a call from the "Microwave Reactor" again 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 last time I bought Qiu Heming to transport TRPL equipment, this time it was also a middle-aged engineer with two younger brothers, all men. They drove a minivan and parked on the side of the road.
Speaking of it, almost all sales related to instruments and optoelectronic materials that Xu Qiu came into contact with in the laboratory were men. There was no girl in his impression. Maybe this industry is where men of engineering get together.
The lead engineer instructed the two younger brothers to carry the instrument, turned around and smiled friendly at Xu Qiu, stretched out his hand, shaking hands, and asked: "Your name?"
Seeing him being so polite, Xu Qiu also politely responded: "My name is Xu, what do you call it?"
The other party said: "Hello, Teacher Xu, 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 would be right to call a teacher.
However, he didn't plan to correct it. He walked directly into the building and showed the two guys who were carrying the instrument. "There is an elevator here, and our laboratory is on the fifth floor."
A group of four people brought equipment and took the elevator to the fifth floor.
Han Jiaying and Chen Wanqing had received news before and waited early at the door of the laboratory.
Everyone entered the laboratory.
"Huh!" Liu Gong said with emotion, "Mr. Xu, your laboratory is quite big."
"Yes, it's about two hundred square meters." Xu Qiuying made a peace, and then looked at the school girl who looked strange and seemed to be holding back her smile, shrugging helplessly.
"Yes, 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 is the instrument going to be placed? It's best to find a fume hood."
"Put it in this fume hood." Xu Qiu pointed to his fume hood, which was cleaned up.
This is the result of previous discussions with his senior sisters and school sisters. 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 chromatograph. , These three can't move, they can only vacate his fume hood first.
Anyway, Xu Qiu will have an experiment to do in the future, just go to the school girl or school sister to get a spot, and it will not have a big impact.
Liu Gong waved to the two younger brothers. The two quickly unpacked and put the microwave reactor into a fume hood. This time, unlike TRPL, it needs to be installed on site. The microwave reactor is an integrated machine, but there are many accessories.
After installing the instrument and plugging in the power supply, Liu Gong began to debug and introduced to Xu Qiu and others:
"Teacher Xu, this is a focused single-mode microwave synthesis host. It uses CEM's patented auto-focus coupled ring microwave technology to continuously output microwaves and ensure that the microwave absorption of all samples is maximized. High-pressure airtight reactions can be performed. React with normal pressure reflux, the maximum reaction volume is 125ml......"
"The instrument includes infrared temperature controller, pressure controller, display screen and operating keyboard, built-in electromagnetic stirring system, polymer lined cavity and microwave attenuator..."
"There are computer interface, network interface, two USB interfaces..."
Xu Qiu interrupted: "Does this need to be connected to a computer?"
"Yes, after connecting to a computer, you can control the heating program and the reaction time," Liu Gong looked at the fume hood of the liquid chromatograph and said, "This should be a liquid chromatograph. You can use this computer to control the microwave. The reactor instrument is just not far away, how about it?"
"Okay, trouble Liu Gong." Xu Qiu thought slightly and nodded in agreement. Before TRPL was a special situation, it would be a waste to buy a computer this time.
"No trouble, this is what we should do," Liu Gong said politely. Then he took out a CD-ROM 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 computer's power-on button, and Chen Wanqing suddenly said, "Wait a minute." She passed a pack of disposable latex gloves to Xiao Zhang, "Operate with gloves, and protect yourself in the organic laboratory. "
"Thank you." Xiao Zhang was taken aback, unpacked the gloves, put on a glove, and proceeded carefully.
"It will take some time for him to install the software. Mr. Xu, let's check if the instrument parts are complete, and then sign the acceptance form." Liu Gong took out an A4 paper in duplicate from the briefcase and handed it over. To Xu Qiu.
Xu Qiu took it over and took a look. There was a long list of parts on the list.
He jumped directly to the bottom. The total price was US$45,800, and the discounted price was US$34,550. Converted in his mind according to the current exchange rate, it was about 200,000, but less than 300,000.
"Liu Gong, let's start checking."
"Okay, Teacher Xu."
"The 10 ml pressure reaction test tube package includes 100 10 ml pressure reaction test tubes, 100 IntelliVent sealing caps, 100 reaction safety membranes, and 50 3 mm stir bars."
Xu Qiu picked up the first package of parts and started to check. He mainly checked whether several parts were complete, but he was not bored enough to carefully count the number of test tubes to see if the number of test tubes was 100.
It is impossible for them to falsify the quantity. The main thing is that there are errors and omissions. For example, there are only test tubes, no sealing caps, or no safety film, which is embarrassing.
"No problem, next one."
"The 35ml pressure reaction test tube package contains a total of 25 sets of 35ml pressure reaction test tubes, sealing caps, safety membranes, and 5 stir bars."
"Well, no problem."
"One 10ml high pressure attenuator, one 35ml high pressure attenuator and one normal pressure attenuator."
"These are okay."
"The electronic version of the operating manual, this small sheet will be installed directly into the computer."
"One condenser support rod, one condenser clamp, and one overflow cup."
"Well, no problem."
"Teacher 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 a few photos of the instrument and parts with his mobile phone and sent them to Teacher Wei.
At this time, Xiao Zhang's software was installed, and Xu Qiu and Liu Gong walked over.
This time, it's not like TRPL gave a temporary activation code, which is directly used forever.
The Liugong operating software demonstrates the operation of the instrument with 10ml and 35ml pressure reaction test tubes and a common 24-neck 50ml flask respectively. The solvent used is a low-toxic ethyl acetate solvent. The main tests are heating function and 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 find out on their own in the future.
Xu Qiu silently copied Liu Gong's skills, 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 the 10 or 35 ml pressure reaction test tube, install the safety film, close the sealing cap, and place it in the card slot inside the microwave reactor.
Next, 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 place where the reaction tube is placed, right-click, load the method, and the corresponding reaction tube will start to execute according to the method.
If the synthesis reaction uses two original specifications of pressure reaction test tubes, it can withstand high pressure, and the reaction temperature can greatly exceed the boiling point of the reaction solvent;
But if an ordinary flask is used~EbookFREE.me~, the reaction conditions should be consistent with normal conditions, and high-pressure reactions cannot be carried out.
After debugging 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 Qiuke set up, seeing the senior sister next to him, the ghost said: "Xiao Chen, send Liu Gong off."
"No, no." Liu Gong waved his hand hurriedly.
Chen Wanqing was stunned for a while, and Xu Qiu gave Xu Qiu a blank look when she reacted, then turned her head and put on a smiling face: "Liu Gong, please here."
Xu Qiu patted his forehead with his left hand. What I said to the senior sister just now...
Forget it, let's go back to the office and wash your hands first. Liu Gong doesn't wear gloves on this equipment.
