Memmert ULT360eco ULT freezer, ultra-low-temperature freezer
The Memmert ULT360eco 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 eco-model, with a practical capacity of 360 litres, offers the optimal combination of maximum process reliability and exceptional energy efficiency , as it has been specifically designed for demanding, resource-efficient continuous operation under GLP and GMP conditions. Cascade cooling and inverter-controlled compressor dynamics The refrigeration heart of the Memmert ULT360eco freezer is based on a high-performance system comprising two cascade-connected inverter 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 the samples and thermodynamically efficient. The first stage uses the environmentally friendly, natural refrigerant R290, whilst the second stage is operated with R170 to reliably achieve the ultra-low target temperatures. Thanks to the pioneering integration of two inverter compressors, the system dynamically and continuously adjusts its cooling capacity in real time to match the actual cooling requirements. When the door is opened, the eco-electronics compensate for the influx of heat and moisture by specifically increasing the rotational speed. In steady-state operation, however, the system runs in the energy-optimised partial-load range, which drastically reduces energy consumption compared to conventional systems , minimises mechanical wear and extends the service life. Material-science barrier function and ergonomics The structural boundary of the Memmert ULT360eco 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 closingby physically equalising the internal vacuum that is created. With a maximum load capacity of 160 kg per shelf and 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 ULT360eco 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 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, via integrated 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 eco-Freezer can be seamlessly integrated into digital Laboratory Information Management Systems (LIMS) and monitored remotely, guaranteeing seamless documentation of the cold chain for audits.

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.

Liebherr SUFsg 3501 Labor-Ultratiefkühlschrank, 382 l, -40 °C bis -86 °C, 996965551
Für die sichere Lagerung hochsensibler Proben bei extrem tiefen Temperaturen braucht es ein kompaktes Gerät, das trotzdem keine Kompromisse bei der Überwachung macht. Der Liebherr SUFsg 3501 ist ein Labor-Ultratiefkühlschrank aus der MediLine-Serie für den Temperaturbereich von -40 °C bis -86 °C, mit 382 l Nettovolumen die kleinste der drei SUFsg-Baugrößen bei LT Laborhandel. Gehäuse und Tür bestehen aus Stahl, der Innenbehälter aus widerstandsfähigem Edelstahl. Extremtemperatur mit geprüfter Stabilität Die Temperatur wird außen digital angezeigt und lässt sich im Bereich von -40 °C bis -86 °C einstellen, bei einer zulässigen Umgebungstemperatur von +16 °C bis 32 °C. Temperaturstabilität und -konstanz werden dabei nach dem Testverfahren EN 60068-3 geprüft. Als Kältemittel kommt das natürliche R 290 zum Einsatz (Füllmenge 150 g), eine umweltfreundliche Wahl mit geringem Treibhauspotenzial. Dreistufiges Überwachungssystem Der SUFsg 3501 meldet Temperatur-, Tür- oder Netzstörungen sofort optisch und akustisch. Bei einem Stromausfall übernimmt eine integrierte 12-Volt-Batterie die Pufferung für mindestens 72 Stunden, deutlich länger als bei den meisten Laborkühlgeräten im Plusbereich. Eine LAN-Schnittstelle ist nachrüstbar, sodass sich das Gerät bei Bedarf ins Labor- oder Klinik-Netzwerk einbinden lässt. Wer eine noch engmaschigere Überwachung braucht, kann das Basissystem um erweiterbare Features wie CO2-Notkühlung und Online-Monitoring ergänzen. Innenausstattung für den Dauerbetrieb bei -86 °C Geschäumte Innentüren sorgen für zusätzliche Isolierung und eine stabilere Temperaturführung im Innenraum, der Innenbehälter sowie die Ablageflächen und Innentüren bestehen aus Edelstahl, leicht zu reinigen und beständig gegenüber den Anforderungen des täglichen Laborbetriebs. Vier Ablageflächen sorgen für eine strukturierte Lagerung, drei davon höhenverstellbar und damit anpassbar an unterschiedliche Behälter- und Boxgrößen. Der massive Aluminiumgriff mit integrierter Öffnungsmechanik erleichtert die Bedienung auch mit Laborhandschuhen, gesichert wird die rechts fest angeschlagene Tür über ein mechanisches Schloss. Abgetaut wird manuell, wie bei einem Gerät für so tiefe Temperaturen üblich. Kompakteste Baugröße der SUFsg-Reihe Mit 382 l Nettovolumen ist der SUFsg 3501 die kleinste der drei SUFsg-Baugrößen bei LT Laborhandel, deutlich schmaler als die größeren Modelle SUFsg 5001 und SUFsg 7001. Wer noch keine großen Probenmengen bei -86 °C lagern muss oder ein zweites, räumlich getrenntes Gerät für eine kleinere Sammlung braucht, findet im SUFsg 3501 ein vollwertiges Labor-Ultratiefkühlgerät mit derselben Elektronik, demselben Überwachungssystem und derselben MediLine-Positionierung wie die größeren Geschwister, nur mit geringerem Platzbedarf im Labor. Die kompaktere Bauform erleichtert außerdem die Aufstellung in Räumen mit begrenzter Stellfläche, ohne bei Temperaturbereich oder Batteriepufferung Kompromisse einzugehen. Aufstellung und Anschluss Mit Außenmaßen von 196,6 x 79,7 x 108,2 cm (H x B x T) und einem Nettogewicht von 226 kg ist der SUFsg 3501 für einen festen Aufstellort im Labor gedacht, dabei aber merklich schmaler als die größeren SUFsg-Baugrößen. Das Gerät arbeitet mit 230 V bei einer Anschlussleistung von 7,0 A und wird mit einem 2.800 mm langen Anschlusskabel geliefert, ein normaler Laborstromanschluss reicht damit aus. Bei einer Gerätebreite von 90,1 cm bei geöffneter Tür sollte ausreichend Bewegungsfreiheit am Aufstellort eingeplant werden. Typische Einsatzbereiche Der SUFsg 3501 eignet sich für Labore, die Enzyme, Reagenzien, biologische Proben oder andere temperaturempfindliche Substanzen dauerhaft bei sehr tiefen Temperaturen lagern müssen, aber nicht die Kapazität der größeren SUFsg-Baugrößen benötigen, etwa in kleineren Forschungsgruppen, Biobanken oder der pharmazeutischen Entwicklung. Gerade wenn Proben über Monate oder Jahre unverändert bleiben müssen, ist eine stabile, gut überwachte Kühlkette entscheidend. Muss beispielsweise bei einem kurzen Stromausfall die Kühlkette trotzdem gehalten werden, überbrückt die 72-Stunden-Batteriepufferung deutlich mehr Zeit, als ein Techniker für die Fehlerbehebung normalerweise braucht. Auch neu aufgebaute Arbeitsgruppen, die zunächst nur einen überschaubaren Probenbestand anlegen, profitieren von der kompakten Baugröße, ohne bei Sicherheit oder Überwachung Kompromisse einzugehen.

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.

Individual requirements & accessories To make optimum use of the 360-litre interior of the Memmert ULT360 ultra-low temperature freezer and to minimise convective heat exchange during sample access, the use of bespoke stainless steel racks and cryoboxes is physically advisable. The system can accommodate up to 264 standard 50 mm boxes. For the vertical storage of heavy sample batches (max. 160 kg per drawer), we recommend an even weight distribution to protect the fibre structures of the drawers.
