The Eppendorf Innova U535 ULT freezer minimizes operating costs while providing superior protection for your critical samples. A combined insulation based on vacuum insulation panels and polyurethane foam enables extremely low energy consumption.
PhysioCare
Besides sustainability, the main focus of our freezers is on ergonomic aspects. Easy closing of the outer door, ergonomic door handle, display on eye-level, or easy-to-clean stainless steel interior are based on the Eppendorf PhysioCare Concept: Safe grip but very light forces needed to open and close the freezer door.
Cost of ownership
When investing in a new ULT freezer, the product price itself is only one aspect. Others include the long-term costs of power consumption and the costs of service and spare parts. Keep in mind, a high-quality ULT freezer will do its job in the lab for 10 years or more.
Sample safety
The Innova line is equipped with reliable heavy-duty compressors (2-stage cascade cooling system). Quick pull-down times enable fast re-use after cleaning/defrosting of the instrument. The freezers have short recovery times after opening as well as built-in voltage stabilizers to provide extra sample safety.
Their temperature range is from -50 °C to -86 °C.
For even higher sample safety, the Eppendorf Innova upright freezers can be equipped with CO2/LN2 back-up systems and a chart recorder. Temperature monitor systems can be used to monitor the freezers remotely.
Sustainability
Sustainability for ULT freezers is a challenge: Maintaining extremely low temperatures of -86 °C for 24 hours a day, 7 days a week needs energy.
By following the epGreen concept, the Eppendorf freezer R&D team developed intelligent solutions where energy savings are combined with durable long-lasting product quality and ergonomic aspects. This future-oriented instrument class provides consumption levels which are ahead of most competitors within this volume class.
Eppendorf Ultra-Low Temperature freezers are among the most energy-efficient in the industry, reducing energy consumption by thousands of kilowatt hours over our competition.
