Liebherr SUFsg 5001 Laboratory Ultra-low Temperature Freezer, 477 l, -40 °C to -86 °C, 993356951
To store highly sensitive samples safely at extremely low temperatures, you need a piece of equipment you can rely on. The Liebherr SUFsg 5001 is a laboratory ultra-low temperature freezer for the temperature range from -40 °C to -86 °C, which reliably stores even sensitive substances. The unit is particularly robust and user-friendly in design; the housing and door are made of steel, whilst the inner chamber is made of durable stainless steel. The SUFsg 5001 is part of Liebherr’s MediLine series for scientific sample storage and, with a net volume of 477 l, represents the medium-sized model of the three SUFsg sizes stocked by LT Laborhandel. Technology and cooling capacity The temperature is displayed digitally on the outside and can be set within a range of -40 °C to -86 °C, with a permissible ambient temperature of +16 °C to 32 °C. Temperature stability and consistency are tested in accordance with the EN 60068-3 test procedure. The natural refrigerant R 290 is used (charge: 150 g), an environmentally friendly choice with a low global warming potential compared to conventional synthetic refrigerants. In the event of faults, the unit issues visual and audible warnings, ensuring that temperature deviations are immediately detected. Via a retrofittable LAN interface, the ultra-low temperature freezer can, if required, be integrated into an existing laboratory or hospital network and monitored remotely. Interior design and ease of use The stainless steel inner chamber is particularly durable and easy to clean, an important factor for day-to-day laboratory operations, especially when samples are regularly stored and retrieved and the interior therefore needs to be cleaned frequently. Foam-insulated inner doors provide additional stable insulation and temperature control. Four shelves in the freezer compartment ensure organised storage; three of these are height-adjustable and adapt to different container sizes, from small cryoboxes to larger sample containers. The solid aluminium handle with an integrated opening mechanism makes it easy to operate, even whilst wearing gloves, as is common in everyday laboratory work. The door hinge is permanently fitted on the right-hand side. Defrosting is carried out manually, which is standard for an appliance designed for such low temperatures, as automatic defrost cycles at -86 °C would be technically more complex and less suitable for sample safety. Typical applications The SUFsg 5001 is designed for scientific use and is suitable for laboratories that need to store enzymes, reagents, biological samples or other temperature-sensitive substances permanently at very low temperatures. Particularly when samples must remain unchanged for months or years, a stable, well-monitored cold chain is crucial; continuous temperature monitoring with visual and audible alarms ensures precisely this, without staff having to check the temperature manually. Research institutions and biobanks requiring long-term storage of sensitive samples Pharmaceutical development requiring a stable, monitored cold chain Clinical laboratories with long-term storage of reagents and biological material Sites wishing to switch to a water-cooled version (H72) if required Three-stage monitoring system In addition to visual and audible alarms in the event of a fault, an integrated 12-volt battery provides backup power for at least 72 hours in the event of a power cut, significantly longer than with most laboratory refrigeration units in the positive temperature range. Those requiring even more comprehensive monitoring can supplement the basic system with expandable features such as CO2 emergency cooling and online monitoring. The SUFsg 5001 is part of the SUFsg series from LT Laborhandel, which includes two further models, the more compact SUFsg 3501 and the larger SUFsg 7001, each featuring the same MediLine positioning and the same monitoring concept. Installation and connection With external dimensions of 196.6 x 92 x 108.2 cm (H x W x D) and a net weight of 254 kg, the SUFsg 5001 is designed for a permanent installation in the laboratory. The unit operates at 230 V with a connected load of 7.0 A and is supplied with a 2,800 mm long connection cable; a standard laboratory power supply is therefore sufficient. As the unit is 101.7 cm wide when the door is open, sufficient space for manoeuvring should be allowed for at the installation site. Given its weight of 254 kg, a sturdy, level access route is recommended for transporting the unit to its final installation site, particularly if the unit is not to be installed at ground level.

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.

Binder UF V 350 ultra-low temperature freezer, −90 °C to −40 °C, 402 l, 9020-0453
Samples requiring long-term storage at minus 80 degrees Celsius need an ultra-low temperature freezer that reliably maintains this temperature, even when the door is opened several times a day. The Binder UF V 350 covers the range from −90 °C to −40 °C and provides 402 litres of usable capacity in the most compact housing in the UF V series. The entire chamber is made of stainless steel and is cooled by a cascade compression cooling machine using the climate-neutral refrigerants R-290 and R-170. Climate-neutral cooling technology and insulation Cooling is provided by a two-stage cascade compression cooling machine using R-290 (propane) and R-170 (ethane) refrigerants. Both are considered climate-neutral and replace the partially fluorinated refrigerants previously used by Binder. Thermal insulation is provided by vacuum insulation panels (Long-life VIPs), which are significantly thinner than conventional foam insulation while providing the same insulating performance, leaving more usable capacity within the housing. At a setpoint of −80 °C and an ambient temperature of 20 °C, the UF V 350 consumes 7.5 kWh/d according to the data sheet, with an average heat output of 310 W. Starting from a room temperature of 22 °C, the freezer reaches −80 °C after 210 min, a value that can be factored into planning sample transfers from another unit. Construction and access to the chamber An outer door leads to two removable stainless-steel inner doors, which divide the chamber into compartments and allow only part of the cold air to escape when opened. An innovative door seal concept reduces ice formation on the seal, while an ergonomic door-closing lever facilitates closing even when wearing gloves. Three flexibly positionable stainless-steel shelves are fitted as standard. The chamber can be upgraded to accommodate up to eleven shelves if required. With the standard configuration of three racks per shelf level, the freezer accommodates up to 264 cryoboxes in the 50 mm format. Each compartment can carry up to 40 kg, with a total permissible load of 160 kg. Monitoring and alarm functions An internal data logger continuously records temperature values and can be read via USB in an open file format without requiring manufacturer-specific software. The freezer can be integrated into a network via the Ethernet interface, while a volt-free alarm contact forwards faults to an existing building alarm system. Three 28 mm diameter access ports at the rear accommodate additional sensors or cables for external monitoring systems. A lockable door handle is available as an accessory. Water cooling is not available for the UF V 350, as this option is reserved for the larger models in the series. Installation and electrical connection The UF V 350 has a net weight of 226 kg and requires at least 100 mm clearance behind the housing and at least 250 mm clearance at the sides to allow air to circulate around the condenser. It connects to a 230 V AC, 50 Hz supply via a CEE 7/7 (Schuko) plug. The unit fuse is rated at 10 A and the rated power is 1.6 kW. With a width of 706 mm and a depth of 938 mm, the freezer fits through most laboratory doors without prior disassembly. UF V series sizes The UF V 350 is the smallest of three sizes in the air-cooled UF V series. If more capacity is required later, the UF V 500 with 501 litres and the UF V 700 with 736 litres are the next larger models. Both have the same temperature range and climate-neutral refrigerants, but are also optionally available with water cooling. This allows a laboratory to add a second freezer from the same series as sample volumes increase, without changing operating procedures. Typical applications With 402 litres of capacity, the UF V 350 is suitable for laboratories purchasing their first dedicated minus 80 degree freezer or wishing to store a smaller, clearly managed sample collection separately from a larger main freezer. Typical applications: Long-term storage of cell lines, plasmids and enzymes in molecular biology research Retained samples in quality assurance and pharmaceutical development A satellite location next to a larger central ultra-low temperature freezer, for example in an auxiliary laboratory Introduction to minus 80 degree storage for smaller institutes and start-up laboratories Technical details Temperature range−90 °C to −40 °C Spatial temperature deviation at −80 °C± 3.5 K Temporal temperature deviation at −80 °C± 4.0 K Cooling time from 22 °C to −80 °C210 min RefrigerantsR-290 and R-170 (climate-neutral) InsulationVacuum insulation panels (Long-life VIPs) Chamber materialStainless steel, removable inner doors Outer doors / inner doors1 / 2 Shelves (standard / maximum)3 / 11 Racks per shelf level3 50 mm cryoboxesup to 264 Maximum load per compartment40 kg Maximum total load160 kg Rated voltage230 V, 1~, 50 Hz Rated power1.6 kW Unit fuse10.0 A Plug typeCEE 7/7 (Schuko) Sound pressure level47 dB(A) Average heat output at −80 °C310 W Energy consumption at −80 °C / 20 °C ambient7.5 kWh/d Chamber volume402 l Internal dimensions W x H x D486 x 1,300 x 636 mm Housing dimensions W x H x D706 x 1,966 x 938 mm Net weight226 kg Wall clearance rear / sides100 mm / 250 mm InterfacesEthernet, USB (data logger) Scope of delivery 1 Binder UF V 350 ultra-low temperature freezer, item 9020-0453 3 flexibly positionable stainless-steel shelves 2 removable stainless-steel inner doors, pre-fitted Operating instructions The lockable door lock, battery-backed alarm system and foam-insulated compartment doors with seals are not included in the scope of delivery.

Memmert ULT Freezer ULT240eco, ultra-low-temperature freezer
The Memmert ULT240eco 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 full compliance with strict SOPs (Standard Operating Procedures). For procurement professionals in the pharmaceutical industry, this eco-model, with a net capacity of 244 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 ULT240eco 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 materials 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 humidity 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 ULT240eco 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 140 kg per shelf and 280 kg for the entire unit, the system is designed for dense sample loading of up to 162 standard 50 mm boxes. Cyber security and Lab 4.0 documentation For scientific quality management, the Memmert ULT freezer ULT240eco 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, 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.

Binder UF V 500 ultra-low temperature freezer, −90 °C to −40 °C, 501 l, 9020-0347
When a sample collection grows beyond the capacity of an initial minus 80 degree freezer, the Binder UF V 500 is the medium-sized model for the next step. This ultra-low temperature freezer covers the same temperature range from −90 °C to −40 °C as the other models in the series and provides 501 litres of usable capacity. Here too, the entire chamber is made of stainless steel and cooled using the climate-neutral refrigerants R-290 and R-170. Capacity for growing sample collections Three flexibly positionable stainless-steel shelves are fitted in the chamber as standard, and the configuration can be expanded to accommodate up to eleven shelves if required. With four racks per shelf level, the freezer holds up to 352 cryoboxes in the 50 mm format. Each compartment may carry a maximum of 50 kg, with a total permissible load of 200 kg, an increase compared with the UF V 350, which allows 40 kg per compartment. If the freezer is later upgraded to the maximum number of eleven shelves, cryobox capacity increases beyond the standard configuration of three shelves without requiring a larger housing. Cooling technology and thermal insulation Like the entire UF V series, the 500 model operates with a cascade compression cooling machine and climate-neutral R-290 and R-170 refrigerants. Thermal insulation consists of vacuum insulation panels, which achieve high insulating performance with low wall thickness. At a setpoint of −80 °C and an ambient temperature of 20 °C, energy consumption is 7.9 kWh/d according to the data sheet, while the cooling time from 22 °C to −80 °C is 360 min. In addition to the air-cooled standard version described here, Binder also offers the UF V 500 with water cooling. This item relates exclusively to the air-cooled standard version with a 230 V connection. Access, sealing and safety An outer door and two removable stainless-steel inner doors divide the chamber into compartments, while an innovative door seal concept reduces ice formation on the seal. The internal data logger records temperature values and can be read via USB in an open format. The freezer can be integrated into a network via Ethernet. A volt-free alarm contact forwards faults to an existing building alarm system, and three 28 mm diameter access ports at the rear accommodate additional cables. As the data logger stores measurements in an open format, records can be evaluated without manufacturer-specific software and incorporated into existing quality management or audit documentation. The freezer can optionally be factory-fitted with CO2 emergency cooling, which cools the chamber in the event of a power failure or cooling machine fault. Installation and electrical connection The UF V 500 has a net weight of 247 kg, while the housing is 826 mm wide and 938 mm deep. Allow at least 100 mm clearance behind the freezer and at least 250 mm at the sides to ensure the cooling machine receives sufficient air at the condenser. It connects to a 230 V AC, 50 Hz supply via a CEE 7/7 (Schuko) plug. The unit fuse is rated at 10 A. UF V series sizes The UF V 500 is positioned between the compact UF V 350 with 402 litres and the large-capacity UF V 700 with 736 litres. All three sizes share the same cooling technology, operating concept and interfaces, allowing a second freezer from the same series to be put into operation without retraining. Binder also offers the UF V 500 with water cooling for locations with an existing cooling-water connection, but this is not part of the standard equipment for this item. The choice between air and water cooling is generally determined by the heat load in the installation room. In air-conditioned server rooms or small ancillary rooms without dedicated air conditioning, the air-cooled standard version is usually the simpler solution. Typical applications The UF V 500 is suitable for laboratories whose sample volume has grown beyond the capacity of an entry-level model but has not yet reached the scale of a biobank. Typical applications: Central long-term storage of cell lines and DNA and RNA samples in research laboratories Retained samples and reference substances in pharmaceutical quality control Sample banks in clinics and diagnostic laboratories with medium throughput Replacement of or addition to a smaller ultra-low temperature freezer as sample volumes increase Technical details Temperature range−90 °C to −40 °C Spatial temperature deviation at −80 °C± 2.5 K Temporal temperature deviation at −80 °C± 1.5 K Cooling time from 22 °C to −80 °C360 min RefrigerantsR-290 and R-170 (climate-neutral) InsulationVacuum insulation panels (Long-life VIPs) Chamber materialStainless steel, removable inner doors Outer doors / inner doors1 / 2 Shelves (standard / maximum)3 / 11 Racks per shelf level4 50 mm cryoboxesup to 352 Maximum load per compartment50 kg Maximum total load200 kg Rated voltage230 V, 1~, 50 Hz Rated power1.6 kW Unit fuse10.0 A Plug typeCEE 7/7 (Schuko) Sound pressure level47 dB(A) Average heat output at −80 °C330 W Energy consumption at −80 °C / 20 °C ambient7.9 kWh/d Chamber volume501 l Internal dimensions W x H x D606 x 1,300 x 636 mm Housing dimensions W x H x D826 x 1,966 x 938 mm Net weight247 kg Wall clearance rear / sides100 mm / 250 mm InterfacesEthernet, USB (data logger) Scope of delivery 1 Binder UF V 500 ultra-low temperature freezer, item 9020-0347 3 flexibly positionable stainless-steel shelves 2 removable stainless-steel inner doors, pre-fitted Operating instructions CO2 emergency cooling, foam-insulated compartment doors with seals and access control are not included in the scope of delivery.

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 laboratory ultra-low temperature freezer, 382 l, -40 °C to -86 °C, 996965551
The safe storage of highly sensitive samples at extremely low temperatures requires a compact unit that nevertheless makes no compromises when it comes to monitoring. The Liebherr SUFsg 3501 is a laboratory ultra-low temperature freezer from the MediLine series, designed for a temperature range of -40 °C to -86 °C. With a net volume of 382 litres, it is the smallest of the three SUFsg models available from LT Laborhandel. The housing and door are made of steel, whilst the inner chamber is made of durable stainless steel. Extreme temperatures with verified stability The temperature is displayed digitally on the outside and can be set within the range of -40 °C to -86 °C, with a permissible ambient temperature of +16 °C to 32 °C. Temperature stability and consistency are tested in accordance with the EN 60068-3 test procedure. The natural refrigerant R 290 is used (charge: 150 g), an environmentally friendly choice with low global warming potential. Three-stage monitoring system The SUFsg 3501 immediately signals temperature, door or mains faults with visual and audible alerts. In the event of a power cut, an integrated 12-volt battery provides backup power for at least 72 hours – significantly longer than with most laboratory refrigerators operating in the positive temperature range. A LAN interface can be retrofitted, allowing the unit to be integrated into the laboratory or hospital network if required. Those requiring even more comprehensive monitoring can supplement the basic system with expandable features such as CO₂ emergency cooling and online monitoring. Interior design for continuous operation at –86 °C Foam-lined inner doors provide additional insulation and more stable temperature control inside the chamber; the inner chamber, as well as the shelves and inner doors, are made of stainless steel, which is easy to clean and withstands the demands of daily laboratory operation. Four shelving levels ensure organised storage; three of these are height-adjustable and can therefore be adapted to different container and box sizes. The solid aluminium handle with integrated opening mechanism facilitates operation even when wearing laboratory gloves, whilst the door – hinged on the right – is secured by a mechanical lock. Defrosting is carried out manually, as is standard for an appliance designed for such low temperatures. The most compact model in the SUFsg series With a net volume of 382 l, the SUFsg 3501 is the smallest of the three SUFsg models available from LT Laborhandel, being significantly narrower than the larger SUFsg 5001 and SUFsg 7001 models. For those who do not yet need to store large quantities of samples at –86 °C, or who require a second, physically separate unit for a smaller collection, the SUFsg 3501 offers a fully-fledged laboratory ultra-low temperature freezer with the same electronics, the same monitoring system and the same MediLine positioning as its larger counterparts, but with a smaller footprint in the laboratory. The more compact design also makes it easier to install in rooms with limited floor space, without compromising on the temperature range or battery buffering. Installation and connection With external dimensions of 196.6 x 79.7 x 108.2 cm (H x W x D) and a net weight of 226 kg, the SUFsg 3501 is designed for a fixed installation in the laboratory, whilst being noticeably narrower than the larger SUFsg models. The unit operates at 230 V with a connected load of 7.0 A and is supplied with a 2,800 mm long connection cable; a standard laboratory power socket is therefore sufficient. Given that the unit is 90.1 cm wide when the door is open, sufficient space for manoeuvring should be allowed for at the installation site. Typical applications The SUFsg 3501 is suitable for laboratories that need to store enzymes, reagents, biological samples or other temperature-sensitive substances permanently at very low temperatures, but do not require the capacity of the larger SUFsg models, such as in smaller research groups, biobanks or pharmaceutical development. A stable, well-monitored cold chain is crucial, particularly when samples must remain unchanged for months or years. If, for example, the cold chain must be maintained even during a brief power cut, the 72-hour battery backup provides significantly more time than a technician would normally need to rectify the fault. Newly established research groups, which initially build up only a manageable sample collection, also benefit from the compact design without having to compromise on safety or monitoring.

Binder UF V 700 ultra-low temperature freezer, −90 °C to −40 °C, 736 l, 9020-0348
For biobanks and central sample archives with high throughput, the Binder UF V 700 is the largest model in the series. This ultra-low temperature freezer covers the temperature range from −90 °C to −40 °C and provides 736 litres of usable capacity in a housing that, at 1,110 mm wide, still fits through standard door openings. The chamber and removable inner doors are made entirely of stainless steel and are cooled using the climate-neutral refrigerants R-290 and R-170. Large-volume storage with high cryobox capacity Three stainless-steel shelves are fitted as standard, and the configuration can be expanded to accommodate up to eleven shelves. With six racks per shelf level, the UF V 700 holds up to 528 cryoboxes in the 50 mm format, more than any other size in the series. Each compartment can be loaded with up to 50 kg, with a total permissible load of 200 kg. If the freezer is expanded to the maximum number of eleven shelves, cryobox capacity grows beyond the factory configuration of three shelves, an advantage for sample archives that continue to grow over many years. Cooling technology for a large chamber volume Cooling is provided by the same cascade compression cooling machine with climate-neutral R-290 and R-170 refrigerants as used in the smaller models, designed for the larger volume. At a setpoint of −80 °C and an ambient temperature of 20 °C, energy consumption is 8.1 kWh/d, while cooling time from 22 °C to −80 °C is 450 min, correspondingly longer than for the smaller models in the series. Thermal insulation using vacuum insulation panels keeps wall thickness comparatively low despite the large volume. As with the UF V 500, the UF V 700 is also optionally available with water cooling. This item describes the air-cooled standard version with a 230 V connection. Monitoring during continuous operation An internal data logger continuously records the temperature and can be read via USB in an open format. The Ethernet interface integrates the freezer into a network, while a volt-free alarm contact reports faults to an existing building alarm system. Here too, the data logger stores measurements in an open format, allowing records to be read without manufacturer-specific software and incorporated into an existing quality management system. For an investment of this scale, a factory-fitted CO2 emergency cooling system is often worthwhile. It provides interim cooling for the chamber in the event of a power failure or cooling machine failure, but increases the housing depth to 1,085 mm. Installation and electrical connection The UF V 700 has a net weight of 288 kg, the highest weight in the series. The housing is 1,110 mm wide and 938 mm deep. Allow at least 100 mm clearance behind the freezer and at least 250 mm at the sides. It connects to a 230 V AC, 50 Hz supply via a CEE 7/7 (Schuko) plug, and the unit fuse is rated at 10 A. When planning installation, it is worth considering the door hinge side and floor load capacity, as the empty weight rises further when fully loaded with up to 200 kg of additional load. UF V series sizes The UF V 700 is the largest of three sizes in the air-cooled UF V series. The UF V 350 with 402 litres and the UF V 500 with 501 litres are also available. All three models share the same cooling technology, the same operating concept via data logger and Ethernet interface, and the same safety features. Several freezers in the series can therefore be combined at one site without different operating procedures. Binder also offers the UF V 700 with water cooling for locations with an existing cooling-water connection, but this is not part of the standard equipment for this item. For a unit in this performance class, heat output in the installation room is more noticeable than with the smaller models, so it is advisable to check existing room ventilation or air conditioning before ordering. Typical applications The UF V 700 is designed for locations with high and continuously growing sample volumes.

Memmert ULT Freezer ULT750eco, ultra-low-temperature freezer
The Memmert ULT750eco 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 full compliance with strict SOPs (Standard Operating Procedures). For procurement professionals in the pharmaceutical industry, this eco-model, with a practical capacity of 750 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 ULT750eco 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 humidity by specifically increasing the speed. In steady-state operation, however, the system runs in an energy-optimised partial-load range, which drastically reduces energy consumption compared to conventional systems, minimises mechanical wear and extends the service life. Material science-based barrier function and ergonomics The structural boundary of the Memmert ULT750eco 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 internal vacuum that is created. With a maximum load capacity of 200 kg per shelf and 400 kg for the entire unit, the system is designed for dense sample loading of up to 576 standard 50 mm boxes. Cyber security and Lab 4.0 documentation For scientific quality management, the Memmert ULT750eco 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, 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, ensuring complete documentation of the cold chain for audits.
