Memmert ULT Freezer ULT1000, ultra-low-temperature freezer
The Memmert ULT1000 ultra-low temperature freezer represents a highly advanced cryogenic system solution for the long-term preservation and storage of biological and pharmaceutical samples in biobanks, university research institutions and industrial laboratories. When handling highly sensitive samples such as RNA extracts, protein isolates or primary cell lines, absolute temperature stability is the primary criterion for physically ruling out any structural damage to the integrity of the samples caused by thermal fluctuations. The ultra-low temperature freezer covers a precisely adjustable temperature range from -50 °C to -86 °C and, thanks to its advanced system architecture, ensures seamless compliance with strict SOPs (Standard Operating Procedures). For procurement professionals in the pharmaceutical industry, this flagship model, with its enormous capacity of 966 litres, offers maximum process reliability and investment value, as it has been specifically designed for demanding, energy-optimised continuous operation under GLP and GMP conditions. Cascade cooling and inverter-controlled compressor dynamics The refrigeration heart of the Memmert ULT1000 freezer is based on a high-performance system comprising two cascade-connected compressors. This cascade configuration is physically necessary to bridge the extreme temperature differences between the laboratory environment and the interior of the chamber in a way that is gentle on materials and thermodynamically efficient. The R455A refrigerant is used in the first stage, whilst the second stage is operated with R170 to reliably achieve the ultra-low target temperatures. Through the integration of inverter-controlled compressors, the system dynamically adjusts its cooling capacity in real time to match the actual cooling demand. When the door is opened, the electronic control system compensates for the influx of heat and moisture by increasing the compressor speed. In steady-state operation, however, the system runs in the energy-optimised partial-load range, which drastically reduces energy consumption, minimises mechanical wear and extends service life. Material-science barrier function and ergonomics The structural boundary of the Memmert ULT1000 ultra-low temperature freezer is defined by a high-quality housing made of textured stainless steel and an interior made of pure stainless steel. This choice of materials guarantees outstanding corrosion resistance against aggressive disinfectants and prevents cross-contamination in multi-user settings at universities. To minimise uncontrolled entropy exchange when accessing the stored cryoboxes, the interior features an intelligent 4-compartment layout, protected by two separate stainless steel inner doors. This thermal barrier ensures that, when accessing samples, only a small portion of the internal volume is exposed to ambient air. A mechanical door lock protects the valuable contents from unauthorised access, whilst an integrated pressure relief vent with a diameter of 26 mm allows the outer door to be reopened immediately after closing by physically equalising the resulting internal vacuum. With a maximum load capacity of 220 kg per shelf and 440 kg for the entire unit, the system is designed for dense sample loading of up to 770 standard 50 mm boxes. Cyber security and Lab 4.0 documentation For scientific quality management, the Memmert ULT1000 ultra-low temperature freezer offers a sophisticated digital operating concept via a 7-inch touchscreen integrated into the outer door, which is positioned ergonomically. Temperature is measured using high-precision Pt1000 resistance sensors, which enable a setting accuracy of 0.1 °C. The cybernetic safety concept includes both visual and audible alarm systems in the event of temperature deviations or an open door, triggered via door-open detection. An integrated backup battery ensures that monitoring and alarm functions are fully maintained even in the event of a total power failure, and that valuable sample batches remain protected. Via modern communication interfaces such as Ethernet LAN and USB, the ULT freezer can be seamlessly integrated into digital laboratory information management systems (LIMS) and monitored remotely, which guarantees seamless documentation of the cold chain for audits.

Customised requirements & accessories To make optimum use of the 966-litre interior of the Memmert ULT1000 ultra-low temperature freezer and to minimise convective heat exchange when accessing samples, the use of bespoke stainless steel racks and cryoboxes is physically advisable. The system can accommodate up to 770 standard 50 mm boxes. For the vertical storage of extremely heavy sample batches (max. 220 kg per drawer), we recommend an even weight distribution to protect the fibre structures of the drawers. For GMP-relevant applications, we are happy to assist you with manufacturer-compliant qualification (IQ/OQ). Please make use of our procurement service to select your cryogenic infrastructure.

Memmert ULT1000eco ULT freezer, ultra-low-temperature freezer
The Memmert ULT1000eco ULT freezer represents the cutting edge of technology and the largest capacity segment in the field of cryogenic system solutions for the long-term preservation of highly sensitive samples. In biobanks, pharmaceutical production facilities and large-scale research institutions, uncompromising temperature uniformity within large containers is the critical factor for the biological and structural integrity of samples. With an exceptional capacity of 966 litres, this system offers sufficient space for large-scale storage processes within a temperature range of -50 °C to -86 °C. Thanks to its strict focus on an energy-optimised operating concept, the ULT1000eco combines maximum storage density with minimal operating costs, thereby fully meeting the stringent criteria for sustainable and validated processes under GLP and GMP conditions. Cascade cooling and inverter-controlled compressor operation The thermal management of this large-capacity cryogenic cabinet is based on a highly advanced cascade cooling system, which is operated by two inverter-controlled high-performance compressors. To provide the enormous cooling capacity required for an internal volume of almost 1,000 litres in an environmentally friendly manner, the system utilises the natural refrigerants R290 and R170. The integrated inverter technology controls the compressor speed dynamically and continuously in real time. In the event of significant load changes – for example, following a prolonged sample withdrawal – the unit immediately mobilises its maximum kinetic cooling capacity to stabilise the target temperature again using the pull-down method. During normal, continuous operation in a closed system, the system switches to a highly efficient partial-load mode. This not only reduces the thermal and mechanical stress on the system components to a physical minimum, but also significantly lowers the laboratory’s carbon footprint and energy consumption. Material-science barrier function and ergonomics The physical boundary of the system is defined by a highly resistant housing made of textured stainless steel and a solid interior made of pure stainless steel. This material-science specification guarantees maximum resistance to abrasive cleaning processes and prevents corrosion during continuous operation. To prevent convective heat transfer when the insulated stainless steel outer door is opened, the interior is divided into four precisely segmented sections, which are further shielded by two separate stainless steel inner doors. A mechanical door lock provides physical access protection for the sample load. Once the outer door is closed, an integrated pressure relief vent with a diameter of 26 mm ensures rapid equalisation of the internal vacuum, so that the door can be reopened immediately at any time. With a maximum load capacity of 220 kg per shelf and a total load capacity of 440 kg, the mechanical structure is optimally designed to accommodate up to 770 standard 50 mm cryoboxes. Cyber security and Lab 4.0 documentation To ensure seamless monitoring as part of quality management, the ULT1000eco features an intuitive communication centre in the form of an ergonomically positioned 7-inch touchscreen in the outer door. Metrological data acquisition is carried out via calibratable Pt1000 temperature sensors, which provide a setting accuracy of 0.1 °C. The integrated safety concept protects the samples through visual and audible alarm systems, as well as continuous door-open detection. A high-performance backup battery ensures that alarm and data-logging functions are fully maintained in the event of a total power failure. Thanks to modern connectivity via Ethernet LAN and USB interfaces, the system can be seamlessly integrated into higher-level Laboratory Information Management Systems (LIMS) for digital remote monitoring and complete cold chain documentation.

Memmert ULT360 ULT Freezer, ultra-low-temperature freezer
The Memmert ULT360 ultra-low temperature freezer represents a highly advanced cryogenic system solution for the long-term preservation and storage of biological and pharmaceutical samples in biobanks, university research institutions and industrial laboratories. When handling highly sensitive samples such as RNA extracts, protein isolates or primary cell lines, absolute temperature stability is the primary criterion for physically ruling out any structural damage to the integrity of the samples caused by thermal fluctuations. The ultra-low temperature freezer covers a precisely adjustable temperature range from –50 °C to –86 °C and, thanks to its advanced system architecture, ensures seamless compliance with strict SOPs (Standard Operating Procedures). For procurement professionals in the pharmaceutical industry, this model – with a generous capacity of 360 litres – offers the necessary process reliability and investment validity, as it has been specifically designed for demanding, energy-optimised continuous operation under GLP and GMP conditions. Cascade cooling and inverter-controlled compressor operation The refrigeration heart of the Memmert ULT360 ultra-low temperature freezer is based on a high-performance system comprising two compressors connected in cascade. This cascade configuration is physically necessary to bridge the extreme temperature differences between the laboratory environment and the interior of the chamber in a way that is gentle on materials and thermodynamically efficient. The first stage uses the refrigerant R455A, whilst the second stage is operated with R170 to reliably achieve the ultra-low target temperatures. Through the integration of inverter-controlled compressors, the system dynamically adjusts its cooling capacity in real time to the actual cooling requirements. When the door is opened, the electronic control system compensates for the influx of heat and moisture by increasing the compressor speed. In steady-state operation, however, the system runs in the energy-optimised partial-load range, which drastically reduces energy consumption, minimises mechanical wear and extends the service life. Material-science barrier function and ergonomics The structural boundary of the Memmert ULT360 freezer is defined by a high-quality housing made of textured stainless steel and an interior made of pure stainless steel. This choice of materials guarantees outstanding corrosion resistance against aggressive disinfectants and prevents cross-contamination in multi-user environments at universities. To minimise uncontrolled entropy exchange when accessing the stored cryoboxes, the interior features an intelligent four-compartment layout, protected by two separate stainless steel inner doors. This thermal barrier ensures that only a small portion of the interior volume is exposed to ambient air when samples are retrieved. A mechanical door lock protects the valuable contents from unauthorised access, whilst an integrated pressure relief vent with a diameter of 26 mm allows the outer door to be reopened immediately after closing by physically equalising the internal vacuum that is created. With a maximum load capacity of 160 kg per shelf (320 kg for the entire unit), the system is designed for dense sample loading of up to 264 standard 50 mm boxes. Cyber security and Lab 4.0 documentation For scientific quality management, the Memmert ULT360 ultra-low temperature freezer offers a sophisticated digital operating concept via a 7-inch touchscreen integrated into the external door, which is positioned ergonomically. Temperature is measured using high-precision Pt1000 resistance sensors, which enable a setting accuracy of 0.1 °C. The cybernetic safety concept includes both visual and audible alarm systems in the event of temperature deviations or an open door, triggered via door-open detection. An integrated backup battery ensures that monitoring and alarm functions are fully maintained even in the event of a total power failure, and that valuable sample batches remain protected. Via modern communication interfaces such as Ethernet LAN and USB, the ULT freezer can be seamlessly integrated into digital Laboratory Information Management Systems (LIMS) and monitored remotely, ensuring complete documentation of the cold chain for audits.

Temperature measurement is carried out using high-precision Pt1000 resistance sensors , which enable a setting accuracy of 0.1 °C. The cybernetic safety concept includes both visual and audible alarm systems in the event of temperature deviations or an open door, triggered via door-open detection. An integrated backup battery ensures that monitoring and alarm functions are fully maintained even in the event of a total power failure, and that valuable sample batches remain protected. Via modern communication interfaces such as Ethernet LAN and USB, the ULT freezer can be seamlessly integrated into digital Laboratory Information Management Systems (LIMS) and monitored remotely, which guarantees seamless documentation of the cold chain for audits.

Individual requirements & accessories To make optimum use of the 750-litre interior of the Memmert ULT750 ultra-low temperature freezer and to minimise convective heat exchange when accessing samples, the use of bespoke stainless steel racks and cryoboxes is physically advisable. The system accommodates up to 576 standard 50 mm boxes. For the vertical storage of heavy sample batches (max. 200 kg per drawer), we recommend an even weight distribution to protect the fibre structures of the drawers. For GMP-relevant applications, we are happy to assist you with manufacturer-compliant qualification (IQ/OQ). Please make use of our procurement service when selecting your cryogenic infrastructure.
