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.

Product Information

When it comes to maximizing sample storage capacity, Eppendorf Innova ULT Freezers set the standard. They 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 mm to 80 mm. These models are ideal for labs short on space.

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.

› Usage of green cooling liquids in Eppendorf ULT freezers for 10 years
› Packaging parts have increasing share of recycled origin
› Packaging is more than 99% recycable (wood, cardboard, PE-foil)
› REACH + RoHS compliant
› ENERGY STAR^® partner
› Marketing material is printed on FSC certified paper, wherever possible focus on pdf only
› Shipment by cargo ship to reduce CO2 footprint

Features

• 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 minimizing 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 unauthorized setting changes

Applications
