Help: Small laboratory reaction tank
Thread Content
I would like to ask where I can buy small reactors for laboratory use. Thank you here
I used to use three-neck flasks as reaction vessels in the laboratory; I’m not sure if there are any special requirements on your part. In most laboratories, glass vessels are used more frequently
Glass instruments are easy to use... Reactors are needed for applications with harsh pressure and temperature conditions
Glassware can be purchased at instrument stores; flasks with three or four necks are available. It’s important to choose flasks with straight necks – if they have angled necks and the amount of material to be added is not large, it may be impossible for the thermometer to reach the liquid surface. In the case of pressure reactions, then a pressure reactor is necessary; such devices can be found easily by searching online. It is preferable to use a flat surface for the pressure vessel, with high-pressure gaskets used for sealing; when a spherical surface is used, the sealing surface can be easily damaged if not handled carefully
I’m not quite sure. The teacher asked us to work on a project with practical applications; in industry, stainless steel reactors are used, and some people also use them in laboratory tests. Therefore, they asked us whether we should use stainless steel reactors as well, as this would be more in line with industrial production practices and would yield better results when scaling up the process. I saw someone using it, but I don’t know where they bought it. I searched online as well, but I’m not sure if the search terms were incorrect. Nothing was found, so I hope the seniors can help. Thank you!
I’m also using a glass three-necked flask at the moment; I’m not sure if, after it’s prepared, I’ll need to use a stainless steel reactor again for pilot testing
High-pressure batch reactors – Weihai Chemical Equipment Co., Ltd. is the company that uses them; you can give it a search to see more
There are quite a few manufacturers of reaction kettles in Weihai, and the quality is pretty good
If pressure plays an important role in your reaction process, it’s best to use a smaller reactor in order to better reflect real-world production conditions. It’s difficult to control pressure with ordinary glass instruments; in our company’s pilot tests, we use glass instruments and are unable to even measure the pressure, which makes it impossible to provide guidance for production.
Thank you to all the seniors. For reactions at atmospheric pressure, the three-neck flasks often stick together and cannot be opened, so I want to use a stainless steel reactor.

Glass reactors work well at pressures below 10 bar, and many people use them. The price is similar to that of stainless steel, and the advantage is that it allows one to see the reaction process
A 10-kilogram force seems too much for a glass, right?
Weihai Chemical Machinery Co., Ltd. – We purchase our high-pressure reactors from there. We have bought reactors with a pressure of over 10 Mpa, in capacities ranging from 0.5L to 10L. They are indeed of good quality; the service is also excellent, and their design capabilities are strong. The only downside is that the prices are on the high side.
It depends on how large the landlord’s requirements are; there are no special demands regarding pressure or temperature, etc
It’s available at ordinary chemical testing companies, or one can inquire with research institutes if it’s hard to find
