ULT Freezer

Maximum protection for samples that matter.

Secure ultra-low temperature storage with high thermal stability, integrated safety mechanisms and energy-optimised cooling technology.

Reliable long-term ultra-low temperature storage 

When it comes to ultra-low temperature storage, one factor is paramount: the reliable protection of your samples over extended periods of time. The Memmert ULT freezer has been developed specifically for this purpose. It combines consistent, precise temperature control with integrated safety features and energy-optimised design for continuous operation. In many life science and clinical applications, the storage of biological materials constitutes the longest stage of the operational process. Samples must be kept stable and protected for days, weeks, or even years. Reliably maintaining defined and uniform conditions is therefore not just a technical detail – it is a critical factor for success.

Key performance features: 

• Temperature range: –50 to –86 °C
• Cooling technology: Dual cascade system, optionally with inverter-controlled compressors (Eco Line) for high precision, energy efficiency and long 
• service life
• Rapid cool-down: High-power compressors and modern control technology ensure an optimal balance of performance and energy consumption
• Sustainability: Natural refrigerants, recyclable materials and energy-optimised components
• Operation: 7” touchscreen with intuitive interface and real-time display of temperature and process status

Even minimal temperature deviations can compromise sensitive samples. The Memmert ULT freezer therefore ensures consistently stable and homogeneous conditions throughout the interior – regardless of the position of the sample
