The Laboratory Refrigerator series provides precise temperature control for storage of biological samples, reagents, and temperature-sensitive materials in research environments. Available in 628L and 1008L capacities, these units maintain the 2-8°C range required for vaccine storage, enzyme preservation, and biological specimen banking. The microprocessor control system delivers 0.1°C temperature accuracy with comprehensive alarm systems for temperature excursions, power failure, and door monitoring.
Engineered with polyurethane cyclopentane insulation and air-cooling refrigeration using R290 refrigerant, these units provide reliable storage conditions for laboratories requiring consistent cold chain maintenance. The dual-door design with integral foam construction minimizes temperature fluctuations during access while automatic defrost functionality ensures continuous operation without manual intervention.
How It Works
The refrigeration system operates through vapor compression cooling using R290 refrigerant in a closed-loop cycle. The compressor pressurizes refrigerant vapor, which condenses in the copper tube aluminum fin condenser, releasing heat to ambient air. The liquid refrigerant then expands through the evaporator coils, absorbing heat from the storage chamber interior and maintaining the specified temperature range.
Microprocessor control continuously monitors chamber temperature via integrated sensors, modulating compressor operation to maintain setpoint within 0.1°C accuracy. The polyurethane cyclopentane insulation provides thermal barrier properties while the automatic defrost cycle prevents ice accumulation that could compromise temperature uniformity. Air circulation ensures even temperature distribution throughout the storage volume, maintaining the specified ≤2°C uniformity across all chamber locations.

Practical Tips
Place calibrated temperature loggers in multiple locations throughout the storage volume during initial validation and quarterly verification.
Why: Temperature uniformity verification ensures all storage locations meet specification requirements for sample protection.
Clean condenser coils monthly using appropriate cleaning tools to remove dust and debris accumulation.
Why: Clean condenser surfaces maintain heat transfer efficiency and prevent temperature stability issues from reduced cooling capacity.
Allow adequate air circulation space around stored materials and avoid blocking internal airflow patterns.
Why: Proper airflow ensures temperature uniformity throughout the storage volume and prevents localized warm spots.
If temperature alarms activate, first verify door closure and check for any airflow obstructions before investigating mechanical issues.
Why: Most temperature excursions result from access-related causes rather than equipment failure, enabling rapid problem resolution.
Maintain continuous temperature monitoring records using independent data loggers for regulatory documentation.
Why: Independent monitoring provides validation data for storage conditions and supports regulatory compliance requirements.
Test power failure alarm functionality monthly and verify backup notification systems are operational.
Why: Power failure protection prevents sample loss during electrical interruptions which could compromise research materials.
Organize samples by access frequency, placing frequently used materials near the door to minimize opening time.
Why: Reduced door opening duration minimizes temperature fluctuations and maintains stable storage conditions for all samples.

Background reading relevant to this product:
What temperature validation procedures are recommended for qualifying this refrigerator for regulated storage?
Perform temperature mapping using calibrated data loggers positioned throughout the storage volume. Record temperature data for 24-48 hours under loaded and unloaded conditions to verify uniformity specifications and establish qualified storage zones.
How should the alarm system be configured for different types of stored materials?
Set high/low alarm limits based on specific storage requirements - typically ±1°C from setpoint for critical biologics, wider ranges for less sensitive materials. Test alarm notification systems including power failure backup functionality during qualification.
What maintenance schedule is required to maintain temperature performance specifications?
Perform monthly temperature calibration verification, quarterly condenser cleaning, and annual comprehensive performance qualification. Monitor defrost cycle frequency and clean door seals regularly to maintain thermal integrity.
Can this refrigerator accommodate standard laboratory storage containers and sample racks?
The internal dimensions of 1100×454×1325mm accommodate standard laboratory storage boxes, specimen racks, and sample containers. Adjustable shelving allows configuration for various container sizes while maintaining air circulation.
How does the automatic defrost cycle affect temperature stability during operation?
Automatic defrost operates during low-demand periods to minimize temperature impact. The system is designed to complete defrost cycles while maintaining storage temperature within specification limits through thermal mass and insulation properties.
What documentation is provided for regulatory compliance and validation purposes?
Consult product datasheet for specific documentation provided. Typical laboratory refrigerators include performance specifications, installation qualification protocols, and factory calibration certificates for validation support.
