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.

The upright model Innova U101 has a limited footprint, especially designed for small labs. The Innova U101 is a personal ULT freezer which fits below a standard bench (stackable as option).

Besides sustainability, the main focus of our freezers is on ergonomic aspects. Easy closing of the outer door, ergonomic door handle, 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 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.

Lost in samples? Stay organized!
Over many years, you collect hundreds and thousands of samples – samples that are the results of years of hard work – samples of high value. When storing these, it is vital to keep them safe and accessible.
Many scientists still use spreadsheets or even paper-based lists to keep track of their storage. While these solutions may work most of the time, they are susceptible to human error, damage, and misplacement.
Keep track of your samples with eLABInventory
eLABInventory is a sample management software.
