Labotemp Laboratory Freezer LDF-18 is designed as a high-performance -40 freezer for secure storage of vaccines, plasma, reagents, biological samples, and temperature-sensitive laboratory materials. Built for hospitals, research institutes, diagnostic laboratories, pharmaceutical facilities, and scientific research environments, this scientific freezer delivers stable temperature control from -20°C to -40°C with precise microprocessor regulation and 0.1°C accuracy. The direct cooling system combined with HC eco-friendly refrigerant ensures reliable low-temperature preservation while maintaining energy-efficient operation for continuous laboratory use.
Engineered for long-term reliability and sample safety, this medical freezer features a durable coated steel cabinet with multiple inner doors to minimize cold air loss during access. The digital display and intelligent alarm system provide real-time monitoring with protection against high/low temperature fluctuations, power failure, sensor error, and door ajar conditions. A built-in backup battery maintains alarm and temperature display during power interruptions, while password protection and door locking improve storage security. Adjustable shelves, low-noise operation, and heavy-duty castors support convenient day-to-day laboratory workflows.
