- Determine the user’s industry
Drug stability test chambers are currently used in the following industries: ① pharmaceutical factories ② food factories ③ cosmetics ④ textile industry ⑤ colleges and universities. Of course, most of them are pharmaceutical companies. If it is used in a pharmaceutical factory, you may wish to ask more about whether it is an API, a finished product, or a traditional Chinese medicine.
- Determine the purpose of the drug stability test box
Usually, customers use the drug stability test box to complete the following experiments:
① research and development of new drugs;
② Drug retention samples (common temperature is + 25 ℃ ± 2 ℃, humidity is 60 ± 5% RH);
③ Sample low temperature storage test (commonly stored at 5 ℃);
④ Accelerated experiments of samples (common temperature + 40 ° C ± 2 ° C, humidity 75 ± 5% RH, lighting conditions: 4500 ± 500LX); ⑤ whether the samples are exported or domestically sold (the possibility of exporting raw materials is greater).
- Determine the three parameters required for the experiment: ① temperature range; ② humidity range; ③ light function
①Temperature range: Considering the experiments and samples taken, the drug stability test box generally does not need too high temperature. Generally, the temperature range we see is 0-65 ℃. Of course, if the drug stability test box is used If you need to bring the light function for the accelerated experiment, the temperature range of the experiment will be divided into 10-50 ℃ with light and 4-50 ℃ without light. Of course, a wider range will appear, but the general temperature is at this temperature. Of this range, it is rarely necessary to exceed this temperature range.
② Humidity range: Similarly, the drug stability test box is considered from the experiments and samples. The general humidity range is: 40 ~ 95% RH. What is the temperature you need to use during your experiment? At this temperature, how much humidity to control, you may wish to determine a few common temperature and humidity points, and then choose
③ Illumination function: Determine if your experiment needs to use the illumination function. If not, of course, you only need to choose a medicine box that controls temperature and humidity. If necessary, let us take the accelerated test of medicine as a reference, which is specified in the pharmacopoeia The lighting condition of the accelerated stability experiment is 4500 ± 500LX, so as long as the light intensity can achieve this parameter, there is generally no problem. The medicine boxes on the market with light function, better can be 0 ~ 6000LX. Time, the error can be less than 500L.
- Determine the volume of the cabinet required for your own sample.
When choosing the size of the cabinet, we usually need to consider two aspects. The first is the location of the laboratory. This requires us to consider the relationship between the size of the cabinet and the size of the laboratory. Whether to enter the laboratory or not. The second is how much space is needed for the experimental samples. In this regard, we need to consider the volume of the inner tank of the cabinet. Now the medicine box is as small as 80L, as large as 1500L, and even several cubic laboratories can be customized.
- Determine the weight of the experimental sample and consider the bearing capacity of the manufacturer’s separator.
This is a detail problem in the selection. If the sample is not too heavy, you do not need to consider it, because the general manufacturer will provide a 15k load-bearing separator. If the thing is very heavy and cannot be placed on different separators separately, then you need Determine the load, and then ask the manufacturer to make a special.

Paperless recorder, printer: for storing experimental data and outputting short messages
Alarm system: Send SMS to the designated person’s mobile phone when the device fails, making the experiment safer and saving human capital.
3Q certification: Generally refers to the installation confirmation, operation confirmation, performance confirmation provided by the manufacturer, and there are formal 3Q certification documents.
