Premium Ultra-Low Temperature Lab Freezers from New Brunswick Scientific are the result of over two decades of design innovations, yielding a highly efficient refrigeration system, proven to perform reliably, year after year. Like NBS Innova® ULT lab freezers, Premium feezers provide quality design, advanced features, and the ability to safely preserve samples over the long term. The main difference is that NBS Premium Freezers utilize traditional urethane insulation, 130mm/5.1" thick, to achieve and maintain ultra-low temperatures of -86°C.
All NBS freezers are exceptionally energy-efficient, saving you thousands of dollars in reduced energy consumption, as well as minimizing the carbon footprint. Cost savings are ensured through use of energy-efficient compressors and outer door seals. For operator convenience, all Premium upright and chest model freezers include an ergonimically-positioned front-mounted control panel, easy-open door, heated air vent with plunger to prevent vacuum formation, with low noise output, remote control option, and heavy-duty lockable casters. Sample security is ensured through password-protecting temperature and alarm settings, keyed locks for outer doors as well as for the on-off power switch, audible and visual alarms for high and low temperature, power failure, low battery and filter, and automatic restart with non-volatile memory after power interrupt. Other advantages include five storage compartments and inner doors on upright freezer models, auto restart, and easy-access and washable filter for long compressor life.
