-20°C Freezers

-20°C Freezers are general-purpose laboratory freezers designed for the safe and reliable storage of temperature-sensitive materials such as enzymes, reagents, vaccines, and biological samples. At Wasteless Bio, we offer a wide selection of repurposed -20°C lab freezers that provide dependable performance for research institutions, diagnostic labs, clinical facilities, and pharmaceutical companies—while helping reduce costs and environmental waste through sustainable equipment reuse. Operating at a stable -20 degrees Celsius, these freezers are ideal for everyday laboratory storage needs that do not require ultra-low temperatures. They are commonly used to preserve molecular biology reagents, ELISA kits, buffers, chemicals, and short-term biological specimens such as DNA, RNA, or microbial cultures. Vaccine storage is another major use case, with many vaccines requiring stable -20°C conditions to maintain efficacy and cold chain integrity. Our inventory includes upright, chest, and under-counter freezer models, offering flexibility in storage capacity and lab layout. Many models come equipped with digital temperature displays, adjustable shelving, temperature alarms, and lockable doors to ensure both sample protection and security. These features are particularly important in regulated environments where sample integrity and documentation are critical. Wasteless Bio frequently lists units from trusted brands including Thermo Fisher Scientific, VWR, Eppendorf, Panasonic, and Liebherr. Each freezer is assessed for performance and functionality, and listings include key details such as internal volume, energy efficiency, compressor type, defrost mechanism, and compatibility with temperature monitoring systems. By sourcing surplus -20°C freezers from Wasteless Bio, you can equip your lab with high-quality cold storage while minimizing capital expenditure and contributing to circular lab practices. Whether you're preserving critical reagents, storing vaccine inventory, or managing research samples, our -20°C laboratory freezers offer the temperature stability, storage reliability, and operational efficiency your facility needs.
