With the use of the laboratory refrigerator, cold is used to inhibit the chemical-physical structure of life and increase preservation. Because of the cold, bacterial growth in the water can be decreased by lowering the temperature. This process ensures the preservation of food in the food industry, but also in cosmetics, pharmaceuticals and research.
Sophisticated laboratory fridges
Today, with electronics and all digital equipment, it is possible to control energy consumption. This is one of the most heartfelt issues to curb the greenhouse effect and global warming. There is a great deal of focus on environmental impact and reducing the ozone hole. All refrigerators must be highly controlled and completely CFC free.
The laboratory refrigerator today must have an ODP (ozone depletion potential) =0; a very low TEWI (total equivalent warming index) a very low GWP (global warming potential).
Application of refrigeration
The refrigerator has many applications in the food, pharmaceutical and health sectors and in all laboratories. Important also is the storage of medicines, blood, plasma, sera and in analysis laboratories in general.
Digital electronic controls
The latest generation of refrigerators have periodic temperature calibration capabilities. Thanks to this technology, the quality of conservation is improved. At temperatures between +15°C and +4°C, drugs, blood and various biological materials are stored. If the refrigerator is ventilated, the temperature is distributed evenly. This slows down degenerative processes and ensures conservation without altering the natural balance.
The temperature of -20°C is the best way to preserve the natural balance of the refrigerator.
At temperatures of -20°C to -50°C, plasma, diagnostic products, sera, histological materials are preserved. At temperatures of -80°C, what needs to be preserved is preserved for years. When temperatures drop to around -130°C, materials are preserved for up to 10 years and more. At these temperatures, life is suspended, but of course the equipment must be highly specialised. To preserve for such a long time, the metabolism of the cell must be stopped and all biochemical reactions suspended.
The refrigerator is therefore a refrigerator.
Therefore, the refrigerator is now a specialised instrument for different preservation needs. Let's take a closer look at the characteristics of this fundamental piece of equipment.
Laboratory refrigerators, specially designed for the pharmaceutical, chemical and analytical fields, are highly durable, reliable, stable and high quality products. Their special function of storing and protecting sensitive substances and flammable products requires that all laboratory refrigerators and freezers, in addition to being robust, high quality and high-tech, must comply with all applicable international safety regulations. According to current regulations, laboratory refrigerators must have an ODP of zero, a very low total equivalent heating index and a very low global warming potential.
Chemical laboratory refrigerator
In a chemical laboratory, where chemical analyses and investigations are carried out and mixtures are created, refrigerators play a key role in the cold storage of medicines, blood and serums in order to avoid altering the natural balance of these substances. Modern refrigerators are equipped with digital equipment with which the temperature can be monitored. In addition, special alarms are able to signal any faults. If the refrigerator is equipped with a fan, this distributes the temperature evenly, helping to slow down any degeneration processes.
Buying guide: laboratory fridge prices
There are various models of fridges on the market, from the more technological ones with digital temperature setting, internal fan and automatic defrosting, to those that include a freezer. There are also versions with a solid door and those with a glass door. Not forgetting those suitable for storing products at risk of explosion. In short, there really is a wide range of models to suit different needs, and each model corresponds to different prices. In any case, for a robust, safe and perfectly reliable product, prices are around one thousand to two thousand euros. This does not exclude that it is also possible to find cheaper and equally functional, but not particularly high-tech models.
Laboratory freezer -80°C
Let us now talk about laboratory freezers, which can be purchased built-in to the refrigerator or even stand alone. Today, laboratory freezers are designed and manufactured for the storage of products or particular biological materials for which accurate storage temperature controls are required. Modern freezers offer a uniform internal temperature with low energy consumption. Freezers ranging from -20 to -50 degrees Celsius are used to store blood, histological tissues and sera. There are also freezers that provide higher freezing temperatures, up to -80 degrees Celsius, and can store products and materials that need to be preserved for very long periods of time, even years.
The most popular freezers are designed and manufactured for the storage of products or particular biological materials for which careful controls on storage temperature are required.
The most popular professional laboratory refrigerators and freezers: Liebherr and Angelantoni
The best brands of professional laboratory refrigerators and freezers include Liebherr and Angelantoni. Both meet high standards in terms of warranty and reliability. The digital electronic controls, the fan that ensures homogeneity of the internal temperature, the automatic defrosting systems and the perfect thermal insulation ensure extraordinary energy savings, thus respecting the environment and limiting operating costs. In addition, the high quality materials and the precision of the controls ensure optimal preservation of products and materials.
