One of the most important parts of efficient lab management is selecting the right laboratory freezer. Finding a reliable used refrigerator that fulfills your specific needs can be difficult.
So, what factors do you need to consider when buying a used laboratory refrigerator? Some of the important ones have been discussed below. Check these out!
Understanding Laboratory Refrigerator
A laboratory refrigerator is a refrigeration device used to store temperature-sensitive items such as biological samples, chemicals, and reagents in research, medical, and scientific settings.
Unlike residential refrigerators, lab refrigerators are designed with precise temperature control and advanced safety & monitoring systems to ensure the integrity of stored specimens. Healthcare facilities and lab professionals use them to keep samples, specimens, vaccinations, and medications at a specified temperature to avoid deterioration.
Laboratory refrigerators exist in various sizes and specifications, but their purpose is the same- to keep objects at the proper temperature. In contrast to typical residential fridges, they continuously and reliably maintain a defined temperature range.
Factors to Consider When Buying Used Laboratory Refrigerators
Here are some factors you should consider while buying used laboratory refrigerators.
Safety Features
When purchasing a used laboratory refrigerator, it is critical to consider safety features like alarms, temperature monitoring, and electronic locks.
- Alarms notify you of potential difficulties like temperature variations, power outages, or system faults, averting the loss of important objects.
- Temperature monitoring is crucial for labs that handle sensitive materials such as vaccines, enzymes, and chemicals.
- Digital temperature monitoring systems offer exact and consistent temperature control, preserving stored items’ quality.
- Electronic locks restrict unauthorized access to sensitive materials and allow only authorized workers to open the unit.
These safety elements enable the secure and efficient storage of important commodities.
Air Circulation
The air circulation system of a used laboratory refrigerator must be evaluated to ensure optimal performance and temperature stability. Forced draft air circulation is advised for properly spreading cool air, keeping temperatures consistent, and reducing temperature variations.
Air circulation is critical for keeping temperatures consistent, especially when storing temperature-sensitive objects. Check the system to verify that it continues to perform optimally and provides stable storage for your lab’s demands.
Temperature Evaluation
When acquiring a used laboratory refrigerator, ensure the temperature control system is trustworthy. Look for a microprocessor controller to provide accurate regulation and inspect for calibration or wear issues. Unlike air circulation, which ensures even cooling, temperature control maintains the set range without fluctuation.
Confirm that vaccine storage supports the specified temperature range, and consider using a data logging device to monitor. Reviewing the unit’s maintenance history can also help assure long-term dependability.
Also, you need to get the machine calibrated after procuring it.
Check Maintenance History
When purchasing a used laboratory refrigerator, it is mandatory to understand the history and maintenance logs. The longevity and efficiency of the unit are determined by its maintenance, frequency of use, and environmental conditions.
Before purchasing, ask about any known difficulties and seek access to the logs, which can provide information about previous repairs, servicing, and calibration. It helps decide whether the used refrigerator is dependable for your lab’s requirements.
Check Build Quality
When choosing a used laboratory refrigerator, it is critical to consider the build quality and durability. Durability and corrosion resistance require high-quality materials such as stainless steel. Even after extensive use, the refrigerator’s stainless steel body emphasizes its durability.
The door seals should be intact and tight, as worn hinges can impair temperature regulation and energy efficiency. The refrigerator body should be inspected for evidence of deterioration or wear that may degrade performance.
A well-maintained old refrigerator with a sturdy construction can serve your lab for years. Investing in a strong, well-built, used laboratory refrigerator can save you money while delivering long-term value.
Laboratory Refrigerator Maintenance
Once you buy the refrigerator for your lab, taking care of it and maintaining its performance becomes important. Check out these points to know more.
Routine Cleaning
- Empty the unit and keep sensitive goods in a temporary place.
- Ensure debris-free seals for an airtight atmosphere inside the refrigerator.
Temperature Management:
- Ensure refrigerators and freezers are set at the correct temperature range.
- Monitor temperatures regularly using dependable logs.
Organisational Strategies
- Organise frequently used goods at the front for easy access.
- Keep longer-lasting goods at the back.
- To prevent cross-contamination, use freezer-safe containers and label them properly.
Energy Efficiency:
- Regularly check and maintain settings.
- Keep seals intact to reduce energy loss.
- Clean the vents and coils regularly to improve energy efficiency.
Conclusion
Buying refrigerators or any other equipment for a lab is a crucial operation. Especially when purchasing used laboratory refrigerators, you have to be more thoughtful.
Here in this blog, every vital aspect that should be considered when buying a used refrigerator has been discussed. So, check it out again, if needed, and make the right purchase.
