Long Term SupportA laboratory refrigerator typically maintains a temperature between 2°C and 8°C (36°F to 46°F). This range ensures safe storage for sensitive materials like samples, reagents, or medications without freezing them.
1. Remove All Contents
Before starting the defrosting process, transfer all items from the freezer into a backup unit. Ensure the backup freezer is maintaining the correct storage temperature for your samples to prevent temperature fluctuations that could compromise integrity.
2. Unplug the Freezer
Disconnect the freezer from the power supply to initiate the defrosting process. It’s best to do this in the morning so you can monitor and manage any ice or water runoff throughout the day.
3. Allow Ice to Melt Naturally
Ice buildup will take time to melt, so regular monitoring and cleanup are essential to prevent water from spreading across the lab. To speed up the process, start from the top and work your way down by gently applying warm water to the coils and shelves using a sponge or spray bottle. Set up a drainage system to direct the melting ice into a bucket or tray. Avoid using sharp tools to remove ice, as this can cause irreversible damage to the freezer.
4. Ensure the Interior is Completely Dry
Once all the ice has melted, thoroughly dry the interior of the freezer. Any remaining moisture can refreeze once the unit is restarted, leading to further ice buildup.
5. Restore Power
Move the freezer back to its designated position and plug it in. Allow sufficient time for the unit to cool down to the required storage temperature before reloading any samples.
6. Return Stored Items
After confirming that the freezer has reached its set temperature, carefully place all samples and inventory back inside, ensuring proper organisation and airflow.
By following these steps, you can effectively defrost your laboratory freezer while maintaining sample integrity and equipment longevity.
A laboratory refrigerator is designed to store temperature-sensitive items like vaccines, medications, biological samples, or chemicals. It provides precise cooling to maintain their integrity for research, medical, or scientific purposes.
The lifespan of a medical fridge can vary depending on several factors including usage, brand and maintenance. Regular maintenance and servicing can extend the lifespan of the fridge.
Regular cleaning of a vaccine fridge is essential to maintain hygiene and ensure the safe storage of temperature-sensitive medicines. The frequency of cleaning depends on usage levels and the type of vaccines stored, but a once a month clean is generally recommended.
A vaccine refrigerator is specifically designed to store vaccines and other temperature-sensitive medical supplies, ensuring they remain within a precise temperature range, typically between 2°C and 8°C. In contrast, a household refrigerator is designed for general food storage and lacks the specialised features required for medical applications.
Key Differences:
Temperature Stability: Vaccine refrigerators utilize advanced compressors and microprocessor-based controls to maintain consistent temperatures, quickly restoring the set temperature after door openings. Household fridges often experience temperature fluctuations, which can compromise vaccine efficacy.
Air Circulation: Medical-grade units employ forced air circulation to ensure uniform temperature distribution throughout the interior. This prevents cold or hot spots that could affect stored vaccines. Household refrigerators may not provide such uniformity.
Alarm Systems: Vaccine fridges are equipped with audible and visual alarms to alert users of temperature deviations, power failures, or door ajar situations, enabling prompt corrective actions. Standard household fridges typically lack these critical monitoring features.
Design and Storage: Medical refrigerators feature smooth, easy-to-clean surfaces and adjustable shelving to accommodate various vaccine sizes while minimizing contamination risks. Household fridges are designed for food storage and may not meet the hygienic standards required for medical environments.
While household refrigerators are suitable for everyday food storage, they do not meet the stringent requirements necessary for preserving vaccine potency and safety. Utilising a purpose-built vaccine refrigerator is essential to ensure the integrity of vaccines and compliance with health regulations.
Our large biomedical refrigerators come equipped with adjustable shelves and offer a spacious net capacity of 1381 litres. They measure 1440 x 860 x 1997 mm (WxDxH), providing ample storage for vaccines, medications, and other temperature-sensitive materials. For maximum storage needs, we also offer double-door models, ensuring optimal organisation and easy access while maintaining precise temperature control.
A medical fridge should be kept between +2°C and +8°C to ensure the safe storage of vaccines, medicines, and other temperature-sensitive supplies. Maintaining this range is essential to preserve the potency and effectiveness of stored products.
To prevent temperature fluctuations, it is important to:
– Monitor temperatures at least twice daily
– Use a calibrated temperature monitoring system
– Avoid overloading the fridge to allow proper airflow
Staying within the recommended medical refrigerator temperature range ensures regulatory compliance, prevents costly product wastage, and helps protect patient safety.
A malfunctioning medical fridge can compromise the potency of vaccines and medicines, leading to costly losses and potential risks to patient care. Follow these critical steps to minimise damage and restore proper storage conditions:
1) Keep the fridge door closed – This helps maintain temperature stability while assessing the situation.
2)Notify vaccine providers & coordinators – Contact your local incident reporting scheme for guidance.
3) Check the last reliable temperature reading – Identify when and why the temperature fluctuated.
4) Quarantine-affected vaccines – Store them separately, label them as “Quarantined,” and monitor temperatures.
5) Document the incident – Record all details, including follow-up actions, for future reference.
6) Dispose of compromised vaccines safely – Follow manufacturer guidance for proper disposal.
7) Repair or replace the fridge – Consult an engineer or invest in a new medical-grade refrigerator if necessary.
8) By acting quickly and following cold-chain management best practices, you can reduce losses, maintain regulatory compliance, and protect patient health.
A medical fridge should be checked at least twice per day, once in the morning and once in the evening, to ensure that temperatures remain within the required range for storing vaccines, medications, and other temperature-sensitive supplies. Regular monitoring helps prevent temperature fluctuations that could compromise the integrity of stored items. For added safety, you may choose to monitor and record temperatures more frequently. Using automated temperature monitoring systems can also provide real-time alerts for any deviations, ensuring compliance with health regulations and best practices.
