Where are the distillation units well-made?
Thread Content
I want to buy an experimental distillation unit with a capacity of 10-15L. I’m not sure where the best quality distillation units can be found; if anyone who has purchased one has any information, please share it. Thank you!
Tianjin University ranks first in chemical engineering nationwide, and Tianda Tianjiu’s packed towers are well-known across the country
We have purchased glass distillation columns from TianDa Beiyang, 1L capacity, and found that their quality is not good; there are many problems with them! I don’t know if He Tian Da Tian Jiu is the same company.
The distillation center at Tianjin University seems to be pretty good too
TianDa TianJiu and TianDa Beiyang are probably not the same company; in terms of technology, Beiyang is better
Tianjiu certainly has better technology than Beiyang. Beiyang actually originated from Tianjiu, but it’s a much smaller entity. Tianjiu is now part of China Haohua Group, and it has great potential for development. As for the products it produces, there’s really nothing to say about them :P
Agree with the person above – you get what you pay for
It seems that everyone thinks Tianjiu is better. Thank you all!
For experimental distillation units, it’s better to use those from Tianjin Beiyang Chemical Engineering Equipment Company. It is a specialized manufacturer of production experimental equipment. The device is supplied as a complete set.
The glass instruments in Shanghai and Beijing are also good: handshake
The distillation towers manufactured by TianDa and East China University of Science and Technology are both of good quality. However, the focus is different: Tianjin University excels in packed towers, while East China University of Science and Technology is unbeatable when it comes to plate towers! :lol :lol
Last year, our laboratory commissioned Tianjin **** Instruments to build a 10L distillation tower; the quality of the mesh ring packing, glass components, and reflux ratio controller was quite good. They did not provide an instrument support cabinet, so their price was very reasonable. Their attitude towards on-site installation and commissioning services was also good – they were quite polite. It might just be a bit lacking in terms of aesthetics. But I think the configuration is quite practical; after all, the equipment isn’t bought for display purposes – what’s important is that it can be used to produce products. You can contact them at tjbyqs@yahoo.cn or ttkxkl@tju.edu.cn. As for the grid-like frame used to support the distillation tower, we spent 300 dollars to have it custom-made at a hardware store locally; it doesn’t look great but it is functional.
