Labotemp -20°C to -40°C Laboratory Freezer LDF-24 provides 328 L of storage capacity for laboratories requiring reliable low-temperature preservation of samples. Operating from -20°C to -40°C at an ambient temperature of 10–32°C, this laboratory freezer features a microprocessor controller, digital temperature display, and NTC sensor for temperature monitoring and adjustment. Its electro-galvanized steel interior and exterior with antimicrobial powder coating support durability and routine cleaning.
Designed for organized sample storage, the LDF-24 features four shelves, lockable caster wheels, and a manual defrost system. The CFC-free R290 refrigerant supports environmentally conscious refrigeration, while the audible and visual alarm system alerts users to high or low temperatures and sensor errors. An optional USB port and remote alarm port provide additional monitoring connectivity when configured. With a power consumption of 330 W and a standard power-failure alarm backup of 8 hours, this freezer suits laboratories that need accessible, compartmentalized storage for temperature-sensitive materials.
