The Liebherr SFFfg 4001 is a high-capacity laboratory freezer with an interior free of ignition sources, purpose-built for the precise low-temperature storage demands of laboratories, research facilities, pharmaceutical environments, and cleanroom applications where the safe storage of flammable materials and consistent, reliable freezing performance are absolutely non-negotiable. With a 316L gross capacity and an adjustable temperature range of -9°C to -30°C, it delivers exceptional frozen storage volume with the precision and safety compliance that sensitive samples, specimens, flammable reagents, and laboratory materials demand.
The ignition-source-free interior eliminates the risk of ignition of flammable vapours inside the cabinet, making the SFFfg 4001 a critical safety solution for laboratories working with volatile substances that cannot be safely stored in conventional freezers. The monochrome display with touch-button controls provides straightforward, precise temperature management, while visual and audible alarms in case of malfunction and a power failure alarm upon mains power return ensure critical storage conditions are never compromised without immediate notification. The volt-free alarm contact enables seamless integration with external building management or alarm systems for comprehensive facility-wide monitoring.
The antimicrobial handle with opening mechanism minimises contamination risk during frequent access, while the mechanical lock and 1 x Ø 10mm access port support the monitoring and security requirements of regulated laboratory environments. Five adjustable glass shelves with a 40kg individual load capacity and a 270kg maximum total load provide flexible, high-capacity storage configuration to suit a wide range of laboratory workflows. Certified to ISO class 5 cleanroom standards and GMP class B, the SFFfg 4001 meets the strictest cleanliness and contamination control requirements for pharmaceutical and life science applications.
Connectivity via the integrated SmartModule with optional WLAN/LAN interface enables seamless integration with Liebherr SmartMonitoring, providing comprehensive documentation and monitoring of measurement and operating data, alarm messages, and appliance statuses — essential for regulated environments requiring detailed audit trails and compliance records. Running on R290 natural refrigerant and consuming just 384 kWh per year, the SFFfg 4001 delivers outstanding energy efficiency backed by Liebherr's decades of expertise in premium laboratory freezer technology.
