Fast, Contact Freezing its cooling coils entirely situated inside the chamber, unlike other brands whose coils are outside the walls of the chamber, 100% of the cooling power is available to freeze the samples and keep them frozen. The placement of the coils throughout the storage volume provides unbeatable homogeneity, so that all samples are maintained under identical conditions, ensuring that evaluations done using these samples can be compared with Since sample containers can be placed directly on the shelves containing the cooling coils, heat is removed by conduction that is many times...

Rugged Design A cooling coil is at the top (naturally the warmest part) of every chamber to reduce temperature gradients. Thick shelves, incorporating the coils, block the gaps between inner doors, limiting air exchange and cooling any air that enters before it reaches the samples. Over the long term, snow is created instead of ice because of the maintenance of the cold air in the sealed compartments. Four independent compartments with insulated doors for Minimized air exchange on opening reduces ice build-up Compartment dimensions match commonly used cryoboxes Washable air filter for...
