A laboratory refrigerator is equipment that allows the effective storage of all types of substances that are refrigerated, whether liquid, solid or homogeneous. This equipment works by lowering the temperature, so it allows controlling the effect that it has on substances whose composition and structure is intended to be preserved, this is because the lower the temperature will be the rate at which chemical and metabolic reactions occur, which deteriorate the compounds. That is why they are used in the conservation of blood and derivatives, biological fluids and tissues, reagents, chemicals, and bacterial strains. 

A refrigerator provides the conditions by which it is possible to store those elements such as blood and blood derivatives that are necessary for diagnosis, research and the provision of health services. Refrigeration is used to:

• Maintain the viability and function of the most important elements of blood.
• Avoid harmful changes in blood components.
• Minimize bacterial overgrowth.

• Microprocessor-controlled system designed for controlled rage of -40ºC to -86ºC for cabinet space with 1ºC increment.
• Settable high temperature and low temperature alarms.
• Automatic clean-filter alarm and sensor error alert.
• Adjustable storage shelf height.
• Optional temperature recorder. storage racks and storage box
• Installation and Application
• Wide rage operating voltage system from 187V to 242V designed to allow units installed in areas with poor voltage condition.
• Suitable for 10ºC to 32ºCambient temperature

The storage and storage system of samples and products within a laboratory, constitutes a significant part of the quality of the final products developed in it. In this sense, the optimal organization of the warehouse, must manage the available resources and prevent the needs, so that the samples and products, always are found when, how much and where they are needed.

Additionally, the laboratory has a storage system of reagents that must be stored at temperatures below 8°C. For this, the use of the deep freezer should be taken into account, being an essential tool for the conservation of samples.
