Overview
Labotemp Laboratory Freezer LDF-15 is an ultra-low temperature freezer engineered for reliable storage of temperature-sensitive biological and medical materials. Offering 936 L usable capacity and a controlled temperature range from -20°C to -40°C with ±0.1°C accuracy, the LDF-15 is built for continuous operation in hospital, clinical and research laboratories. The unit combines dual SECOP compressors, 120 mm PURF insulation and a stainless-steel interior to ensure stable performance and easy maintenance.

Key features

• Large usable volume: 936 L for bulk sample and batch storage.
• Precise temperature control: microprocessor controller with PTC sensor; accuracy ±0.1°C; range -20°C to -40°C.
• Redundant cooling: dual SECOP compressors for improved reliability.
• High insulation: 120 mm PURF multi-layer insulation to minimize thermal loss.
• Stainless-steel interior and adjustable shelves for corrosion resistance and flexible organization.
• Direct cooling with manual defrost for controlled frost management.
• Comprehensive safety: audible/visual high-low alarms, sensor error alerts and 72 h power-failure alarm.
• Data & monitoring: USB data port and remote alarm interface; RS485 optional for system integration.
• Access control: password-protected operation and door lock for sample security.
• Lab-ready: low noise (50 dB), 4 castors for mobility and durable coated-steel exterior.

Applications

• Controlled storage of temperature-sensitive biological materials (plasma, vaccines, reagents, enzymes, prepared samples) requiring -20°C to -40°C stability.
• Suitable for hospital laboratories, blood banks, clinical testing facilities and research institutes for sample preservation, batch storage and QC under monitored conditions.
