The Eppendorf Innova U535 ULT (ultra-low temperature) freezer minimises operating costs while providing superior protection for your critical samples at -80°C. A combined insulation based on vacuum insulation panels and polyurethane foam enables extremely low energy consumption for long-term sample storage. When it comes to maximising sample storage capacity, Eppendorf Innova ULT freezers set the standard. These lab freezers take advantage of ultra-efficient, ultra-compact vacuum insulation panels which are used in combination with traditional insulation to slim down the freezer wall thickness from 130 to 80mm. These models are ideal for labs short on space when -80°C are needed.

• Easy closing of the outer door, ergonomic door handle, display on eye-level, and 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
• 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 stabilisers to provide extra sample safety.
• The freezer 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 backup systems and a chart recorder. Temperature monitor systems can be used to monitor the freezers remotely.
• 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
• Vacuum insulation panels allow for increased internal capacity with the same footprint as traditionally foamed freezers
• Inner doors are gasketed as well as insulated creating 3 separate compartments minimising cold air loss while you access your samples
• Easy-to-read, eye level, flush mounted LED control panel and alarm status
• Each shelf is adjustable in height for additional storage flexibility
• Special vacuum vent with plunger ergonomically located at waist level to gain immediate access to your freezer
• Inner doors can be quickly removed without the need for tools for easier and faster defrosting
• Full stainless steel interior for easy cleaning during maintenance and defrost cycles; powder-coated steel exterior
• Special low-temperature outer door seals allow gaskets to remain flexible at -86°C and prevent ice buildup for easy access to samples
• Password protection of alarm and temperature setpoints to prevent unauthorised setting changes
