In fact, you can put plates in refrigerator. It is cheap and simple. Maybe the temperature is not stable, but don't warry, acturaly, the dynamic temperature is benifit to grow crystals. You can look for relational papers.
Of course, you can buy a incubator, which can control temperature from 4-60 degree. It is also cheap. It is about 3000CNY in Shanghai. Don't warry, many people put their plates in incubator with a little vibration. In fact, it is not very important. hello everyone can anyone recommend an affordable low temp. incubator that could be used for crystallography? we do not have cold room, so hope the incubator can go to 4 degree withouth too much vibration any size from 10 cubic ft -->20 cubic ft will be fine any help is highly appreciated.
