Helmer Scientific announces the i.Series Ultra-Low Freezer line for the storage of biological samples in clinical and research markets. Designed for performance and protection, the freezers include a cascade refrigeration system to optimize and protect the compressor, providing more energy efficiency. The cabinet is designed with a heat barrier system to keep heat out, resulting in better temperature uniformity and less frosting. The freezers are controlled and monitored by the i.C3 Information Hub, which places the freezer information on a 7-inch color touchscreen. The Ultra-Low Freezers also offer improved serviceability with intelligent component placement, line-of-sight to serviceable components, tool accessibility, and diagnostics history available immediately through the i.C3 Information Hub.
