The Infrico Medcare Ultra Low Chest Freezer Lab Care Plus (-86°C) is a professional-grade laboratory freezer designed for ultra-low temperature storage. It is classified as CLASS I for protection against electric shock and operates under a continuous operation mode according to UNE_EN_60601. This device is manufactured under strict quality controls and is designed for use in unclassified hazardous locations or for the storage of flammable elements, provided safety measures are followed.
Function Description
The primary function of the Infrico Medcare Ultra Low Chest Freezer is to maintain ultra-low temperatures, specifically -86°C (-122.8°F), for the safe storage of samples in research and general laboratory settings. It is intended for indoor use only and requires adequate air circulation to ensure efficient refrigeration. The freezer is designed to prevent rapid temperature increases, even with frequent door openings, by replacing the air in the interior chambers. This creates an ice-free environment, which helps maintain stable temperatures and protects stored items.
