I know of one bad experience with a common refrigerator as it pertains to the freezer. The refrigerator was great for the 4 deg crystallization trials, but the freezer had a "frost-free" cycle which was destroying protein and chemicals. The user was keeping lots of their sensitive items in the door and front edge of the freezer, and in small volumes; they would heat up and get destroyed. Complaints were made for sime time before they realized the true cause.
It was resoled by placing all small eppendorf tubes and vials in thicker plastic boxes for the heat sink characteristics.

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. ________________________________ The New Busy is not the too busy.
