Do you need reliable, large-capacity freezer storage to protect temperature-sensitive samples, vaccines, or reagents? Are you concerned about sample loss due to temperature fluctuations, power outages, or inadequate alarm systems? The MSLF25IN940SWISS Laboratory Freezer is a high-performance upright freezer engineered to meet the demanding needs of modern laboratories, biobanks, and pharmaceutical facilities. With a spacious 936-liter capacity, a stable temperature range of -10°C to -25°C, and a robust security and alarm system, this freezer provides the dependable storage environment your critical materials require, ensuring both safety and compliance.

Why Choose the MSLF25IN940SWISS Laboratory Freezer? Solving Sample Security, Reliability & Monitoring Challenges

Protect your valuable research materials with intelligent features that directly address common lab storage pain points.

• Eliminate Risk of Sample Loss from Temperature Excursions: A temperature spike can ruin months of work. This laboratory freezer features a powerful cooling system with dual SECOP compressors, ensuring rapid temperature recovery after door openings and uniform stability throughout the 936-liter chamber. The microprocessor controller with a digital display allows precise adjustment and monitoring of the temperature from -10°C to -25°C.

• Ensure 24/7 Protection with Comprehensive Alarms: Unnoticed door openings or power failures are a major cause of sample loss. The unit is equipped with a multi-faceted alarm system that provides both audible buzzing and visible flashing light alerts for:

• High/Low temperature deviations

• Power failure (with a 72-hour backup alarm system)

• Sensor malfunction

• Temperature controller malfunction

• Door ajar

• Ambient temperature abnormalities

• Abnormal voltage

• Maintain Stable Temperatures and Energy Efficiency: Fluctuations in room temperature or voltage can impact freezer performance. The MSLF25IN940SWISS is built with high-density CFC-free urethane foam insulation for rigidity and temperature stability. It also features wide voltage tolerance (187~242V/AC) , ensuring consistent operation even in areas with unstable power supply.

• Enhance Sample Traceability and Data Integrity: Meeting regulatory standards requires reliable data. The freezer includes a standard USB port for convenient temperature data logging. An optional temperature data logger and remote alarm connection provide additional layers of monitoring and traceability for GMP and clinical trial environments.
