Talking about the experience of experimenting for more than 24 hours
At present, many laboratories have to conduct experiments for more than 24 hours, and researchers cannot work for long hours. However, the experiments cannot be stopped at night, and some experiments must be performed at night, such as heating or condensing some experiments substance! If left unattended at night, fires and explosions can easily occur. So, this article talks about some experience of experimenting for more than 24 hours, of course, part of it is obtained from the Internet! for reference only!
For reaction experiments, high-temperature reflux cycles are generally required. If the heating is stopped halfway, the yield of the experiment will be reduced, and the lowered yield may affect your experiment process, and the cost of the experiment will increase. The raw materials are not cheap, so you have to keep a vigil in the laboratory for more than 24 hours!
The following are some experiences of netizens:
1. Check the equipment to ensure reliability and safety; (this is difficult to guarantee, only use stable and reliable instruments as far as possible, my classmate has the experience of overnight explosion of the newly purchased voltage regulator)
2. Oil bath heating;
3. The condensate is circulated by the pump, do not use tap water directly, the tap water pressure is unstable, the water pressure increases at midnight, and the joint may be stretched;
4. It is best to use temperature control relays. After actual measurement, the power voltage of the late-night market can reach 300V. If only the voltage regulator is used to control the temperature, high temperature overnight is very dangerous.
5. Ask your classmates to watch during the day. You can sleep at night, but you should use an alarm clock to check every hour to see if the oil temperature is normal, the condensate is flowing, and the reaction is normal.
I have seen many accidents in the laboratory, and I have seen doctoral students failing to obtain a diploma because they burned the laboratory. Experimenting is definitely safety first! If something goes wrong, neither you nor your mentor can bear the responsibility.

Our company just makes a reminder! Regarding the experiment on the time, from our perspective, the quality of the experimental instrument is particularly important!
Therefore, we recommend that the majority of friends, do experiments, instruments can not be chosen at random!
At the same time, our company provides various laboratory instruments: low temperature thermostat, low temperature coolant circulation pump, low temperature thermostat circulator, low temperature thermostat reaction bath, high and low temperature circulation device, cooling water circulation machine, special thermostat for testing, high temperature circulator, constant temperature Water tank, constant temperature oil tank, experimental electric heating plate, ultra-clean workbench, etc ...
