Laboratory refrigerators are equipment whose task is to store liquids and different materials in a controlled environment (refrigerator space), so that they are kept in proper conditions, the lower the temperature, the less chemical and biological activity it has.
There are two main types of refrigerators in the health sector: laboratory refrigerators and pharmacy refrigerators. Both should allow easy and thorough cleaning of surfaces and should offer high reliability, mainly with regard to temperature control. Some models also offer automatic defrost and/or forced air cooling.
They are mainly used to protect samples and reagents. They maintain a constant temperature to minimize the risk of cross-contamination or explosion of volatiles. In order to maintain a stable and uniform temperature, many refrigerators have a cooling fan that circulates the air inside the device. When the refrigerator door is opened, the fan stops automatically to prevent the cold from escaping. In addition, they are usually equipped with separate compartments to prevent cross-contamination. These devices can also be used to store blood and vaccines. However, there are also refrigerators specifically designed for blood storage and preservation, so-called blood bank refrigerators.
They are intended to refrigerate and store medicines and vaccines in conditions that guarantee their preservation. They provide reliable cooling and stable temperatures. They have an alarm system that activates if there is a power outage or the refrigerator door is left open. This system is necessary to avoid situations that can lead to an increase in the temperature inside the device (especially in summer). Likewise, they have a safety system that prevents the temperature from dropping below zero degrees Celsius. Refrigerators intended for the storage of sensitive drugs are usually equipped with a locking system that allows access to them to be controlled.
What features should be considered when choosing a refrigerator?
In addition to the intended application, choosing a refrigerator should also consider the capacity, the temperature range it offers, the configuration, and the number and type of doors.
Capacity: Storage volume is decisive and your choice depends on the type of service for which the refrigerator will be used.
Temperature Range: A very important criterion. Most refrigerators have a temperature range between 2 and 8 degrees Celsius based on quality standards.
Configuration: It should be chosen based on the available space in the laboratory or pharmacy. Upright refrigerators or cabinet refrigerators are the most common, but there are also chest refrigerators. There are also built-in refrigerators that are installed under the laboratory table. In general, the latter has a lower storage capacity.
Number and types of doors: Refrigerators can have between one and four doors, which can be solid or glass.
What points should you consider for the correct operation of your laboratory refrigerator?
It should be noted that for the best performance of refrigerators, it is necessary to place them in a cool and ventilated environment. There should be at least one window to prevent the area from heating up.
When installing a laboratory refrigerator in your premises, it is necessary to follow the manufacturer’s recommendations. In order to properly maintain the equipment, we also recommend that you keep it completely away from any sunlight, this way it will perform at its best.
In addition, you should place it at least 15 cm from the wall, this also helps with air circulation, thus ensuring that its useful life lasts as long as possible.
