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.

“The ULT ensures stable storage with precise temperature control, fast recovery and excellent temperature uniformity.”

Daniel Wettki

Head of Refrigeration Technology Development at Memmert

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

Typical Applications

Safety

The multi-layered safety concept consists of four levels:

1 Visual, Audible Alarms
2 Battery-Backed System
3 Optional CO₂ or LN₂ Emergency System
4 Remote Monitoring

ICO + ULT Freezer

With the new ICO CO₂ incubator and the ULT freezer, Memmert provides a seamless solution covering key steps of the process chain. Together, both systems support a consistent and reliable workflow by covering essential stages in sample handling:

Cultivation and incubation of sensitive cell cultures
Cryopreservation and long-term storage at ultra-low temperatures

Having one partner for both applications means:

Fewer interfaces to manage
One solution for remote monitoring and documentation
Streamlined workflows
Maximum protection for your samples

Premium Quality

Constructed from high-quality 1.5 mm stainless steel, the housing offers outstanding operational reliability and long-lasting protection against corrosion.

Inventory System

The flexible interior design concept, combined with a versatile range of accessories, keeps samples perfectly organised while making the most of the available space.

Each ULT freezer features separately partitioned compartments that are individually accessible. This helps maintain stable temperature conditions — even when doors are opened.
