Laboratory Refrigerators and Freezers Are Designed To Safely Store Temperature-Sensitive Medical5/19/2023 Laboratory refrigerators and freezers store non-volatile reagents and biological specimens at stable, low temperatures. They help prevent bacterial contamination and volatile material explosions. They are used in pharmaceutical units, hospitals, blood banks, production facilities and material testing and diagnosing labs.
Choose from a variety of sizes and features. ENERGY STAR®-certified models save energy by using advanced cooling compressors and advanced temperature control systems. The ENERGY STAR program is an initiative by the Environmental Protection Agency and US Department of Energy to encourage the use of high-efficiency products. These products help reduce greenhouse gas emissions and air pollutants while saving energy costs and increasing product performance. The ENERGY STAR label is easily recognized with its bright teal color and the US government-backed energy efficiency logo. It is found on a wide variety of products including major appliances, office equipment and building materials. Laboratory refrigerators and freezers consume a significant amount of energy in a typical research university lab building. The ENERGY STAR specification is expected to lower energy utilization and life cycle cost for this important category of laboratory equipment. Helmer Scientific is proud to provide a selection of ENERGY STAR certified laboratory-grade blood bank, pharmacy and ULT freezer models. These products are a great way to help reduce the laboratory's carbon footprint while providing secure storage for critical samples and reagents. The refrigerators and freezers that medical facilities use are designed to maintain a tight temperature range. This is critical in order to protect biological materials and vaccines. The refrigeration systems in these appliances are more efficient than household units, and they can quickly respond to temperature excursions. Laboratory-grade refrigerators and freezers offer other features that help prevent contamination, including separate storage areas for different samples. Some of these appliances are also equipped with alarms that warn staff when the temperature reading changes or the door is open. Laboratory fridges and freezers that use Opti Cool cooling technology consume 50%- 60% less energy than conventional models, without compromising performance or functionality. Local and remote alarming systems signal temperature excursions beyond the set parameters, allowing labs or healthcare facilities to take action before the products lose their potency or patients experience re-vaccination or other negative side effects. Compared to standard refrigerators, medical-grade freezers offer superior temperature uniformity and quick recovery after door openings. They also feature self-closing doors with ADA-compliant full-length handles and internal circulation to minimize temperature variation within the appliance, which helps preserve the integrity of stored items. Medical-grade refrigerators and freezers typically come with microprocessor digital controllers for easy configuration of temperature settings, audible and visual alarms, alarm relay contacts and casters. These features improve storage conditions, reduce noise distractions for staff and increase energy efficiency. They also help keep temperature-sensitive materials and products safe even during power outages. The temperature-sensitive materials that medical laboratories, clinics and hospitals work with—including reagents, vaccines and culture media—deserve a stable environment to ensure their effectiveness. That means that these pharmaceutical-grade refrigerators have sophisticated digital monitoring systems to alert staff when temperatures are out of range. The technology behind this digital monitoring has improved tremendously from the old liquid thermometers that required staff to hand record refrigerator and freezer temperatures on a paper log sheet twice daily, a process that was subject to both measurement and transcription errors. Some of the more advanced laboratory refrigerators include thermal buffers around the probe, which eliminate the sudden air temperature changes that bare probes detect and can cause data to spike in the monitoring system. These buffers also help mitigate the normal cycling of the compressor, which can otherwise lead to erratic temperatures that trigger false alarms.
