When it comes to laboratory instruments, what is everyone's first reaction?
Many people will put the laboratory and high-end, precise, rigorous... Words such as these are linked, so the impression of laboratory instruments is generally high-end instruments of precision instruments and the like. So, what happens if something goes wrong with the instrument?
Quickly contact the engineer, the engineer with a professional team and the alloy suitcase that does not leave the hand rushed to the scene, after failure→ quarrel→ disagreements→ cooperation, finally fixed the machine, and then a happy smile appeared on the face, maybe also produced a chicken soup story (yes, that expert: I draw a circle may only be worth a dollar, but know where to draw is worth 999 dollars)...
wrong!
We would shout: Master Brother! Master was captured by the youkai! This machine is broken and you see!
The master brother will come over, professionally ask about the operation process, and then use professional techniques to "snap" and shoot twice...
Yes, in addition to the particularly expensive instruments, we encountered a problem with the machine, and the first reaction was to shoot twice...
What should I do if I don't get better after shooting? It's time for a maintenance engineer to show up, right?
Wrong!
We'll fix it ourselves!
Don't underestimate the hands-on ability of a science student!
You know, it's not a surprise to make an instrument with your bare hands.
When building high-end laboratories or professional platforms, such as "China Tianyan", there are construction indicators at the time of construction, and each component must meet the specified design indicators. If the part is available in the market to meet the requirements of the indicator, and the price is not too much than expected, it will generally be purchased off-the-shelf. If the components on the market can not meet the construction needs, then will do their own, of course, like the "Chinese Tianyan" such a large scientific device needs the components, is not the laboratory itself can produce, generally by the laboratory design or even to provide related technology, and then handed over to the relevant enterprises responsible for production.
If you go back to the earliest origins of instruments, you can find that many instruments are handmade by scientists for a specific experimental purpose, or to verify the theory proposed by a theorist. In fact, even now, when manufacturing and technology are booming, many basic research laboratories, such as the spectroscopy laboratory, researchers still build their own instruments to achieve special needs. The newly built instruments and even the scientific instruments were written and published in papers.
AIP's Review of Scientific Instruments is a book dedicated to publishing a variety of instruments and devices, and has a long history, and many of the major advances that have changed the way research in the entire field are made.
Of course, in addition to these lofty reasons, some laboratories are due to insufficient funding, buying equipment eliminated by foreign laboratories at low prices, and then coming back to modify themselves... A handful of bitter tears...
Therefore, the people in the laboratory have a wealth of theoretical knowledge, and science students have a little handiwork hobby, encounter simple problems with the instrument, the first reaction is to try to repair it, and they will contact the instrument after-sales service if they can't figure it out. After all, understanding is understanding, and professional or incomparable.
