John Morris Group is the authorised Australian & distributor of Memmert - precision temperature control since 1933
Manufactured in Germany
Over 90 Years of
Temperature Control Excellence
Founded in Germany in 1933, Memmert has grown into a globally recognised manufacturer of precision temperature-control instruments. The new ULT Freezer is part of their NextGen platform, engineered to protect your most critical biological samples with uncompromising reliability, sustainability and connectivity.
Why Choose the Memmert ULT Freezer?
Every design decision in the ULT Freezer serves one purpose: protecting your samples with absolute reliability, day after day, year after year.
4-Level Safety Concept
Multi-layered protection combining visual and audible alarms, battery-backed systems, optional CO₂ or LN₂ emergency cooling, and full remote monitoring to safeguard samples at all times.
Dual Cascade Cooling
High-performance dual cascade compressor system delivers precise temperatures down to -86°C with rapid cool-down. Available with optional inverter-controlled compressors (Eco Line) for maximum energy efficiency.
Exceptional Temperature Uniformity
Consistent and homogeneous temperature distribution throughout the entire interior, regardless of sample position. Even minimal deviations can compromise sensitive samples - the ULT eliminates that risk.
Natural Refrigerants
Uses natural, low-GWP refrigerants alongside recyclable materials and energy-optimised components. Designed for laboratories committed to reducing their environmental footprint without compromising performance.
7" Touchscreen Interface
Intuitive 7-inch touchscreen provides real-time display of temperature and process status. Simple, clear operation with full access to settings, alarms and data logging from the front panel.
Remote Monitoring and Alerts
Live alarm notifications sent directly to your mobile device for critical situations. Full remote monitoring via myChamber ensures your samples are protected and visible anytime, anywhere.
Flexible Inventory System
Separately partitioned and individually accessible compartments maintain stable temperatures even when doors are opened. Height-adjustable shelves and flexible configurations accommodate different sample formats.
Premium Stainless Steel Construction
Housing constructed from high-quality 1.5 mm stainless steel for outstanding operational reliability, long-lasting corrosion protection and a durable finish suited to demanding laboratory environments.
Eco Line - Inverter Compressors
The Eco Line models feature inverter-controlled compressors that dynamically adjust cooling output to match demand, delivering high precision temperature control with significantly reduced energy consumption.
Built for Critical Long-Term Sample Storage
From biobanking to vaccine storage, wherever ultra-low temperature preservation is essential, the Memmert ULT Freezer provides the stability and security your samples demand.
Biobanking and Cell Line Preservation
Long-term storage of biological materials including DNA, RNA, proteins, enzymes, serum and tissue samples, where consistent ultra-low temperatures are critical to maintaining integrity over months or years.
Vaccine Storage Including mRNA
Ultra-low temperature storage for mRNA vaccines and other temperature-sensitive biologics, with multi-layered safety systems that guarantee uninterrupted cold chain integrity.
Pharmaceutical Research and Stability Testing
Controlled ultra-low storage conditions for drug compounds, reference standards and stability study samples, supporting regulatory compliance and reproducible research outcomes.
Clinical Trials and Sample Preservation
Preserve patient samples collected during clinical trials with the temperature precision and audit trail capabilities required for GCP-compliant storage and regulatory submissions.
Blood, Serum and Tissue Banks
Reliable long-term archiving of whole blood, serum, plasma and tissue specimens in hospital pathology laboratories, blood banks and forensic facilities.
Microbiology and Research Laboratories
Supports microbiological culture preservation, enzyme storage and general research sample archiving across university, government and industrial laboratory settings.
Ten Models to Suit Every Lab
Standard and Eco Line versions available across five capacities. All share the same NextGen platform, dual cascade cooling and 4-level safety concept.
Each model also available as an Eco Line variant (ULT240eco, ULT360eco, ULT500eco, ULT750eco, ULT1000eco) with inverter-controlled compressors for superior energy efficiency.
Key Performance Data
Pair with the Memmert ICO CO₂ Incubator
Memmert provides a seamless solution covering the full sample handling workflow. The ICO CO₂ incubator and ULT Freezer work together to support cultivation, incubation and long-term cryopreservation in one integrated ecosystem.
