Controlled Rate Freezer

Controlled Rate Freezers are specialized cryopreservation systems designed to precisely manage the cooling process of biological materials, ensuring sample viability and structural integrity during freezing. Unlike conventional freezers, which may expose samples to damaging ice crystal formation, controlled rate freezers allow researchers and clinicians to define exact temperature ramp rates for optimal preservation. At Wasteless Bio, we offer high-quality, repurposed controlled rate freezing systems that support cost-effective and sustainable biopreservation for research labs, fertility clinics, and biomanufacturing facilities. These systems are critical for the successful cryopreservation of stem cells, embryos, oocytes, sperm, blood products, and other sensitive biological samples. By gradually and uniformly lowering the temperature at programmable rates—often in the range of 1°C per minute—controlled rate freezers minimize cellular damage caused by intracellular ice formation, making them essential in regenerative medicine, reproductive biology, and cell therapy applications. Controlled rate freezers are typically equipped with advanced features such as programmable freezing protocols, integrated temperature sensors, real-time graphical data logging, and alarms for temperature deviations. Some models also support multi-sample freezing and remote monitoring, allowing for consistent and reproducible cryopreservation workflows in high-throughput or clinical-grade environments. Units available through Wasteless Bio vary in size, sample capacity, and freezing range, with configurations suitable for both benchtop and large-volume use. Listings include full technical specifications such as cooling ramp rates, final hold temperatures, programmable steps, sample compatibility (e.g., cryovials, bags, straws), and optional integration with cryostorage systems. By sourcing surplus controlled rate freezers from Wasteless Bio, your lab can reduce procurement costs while accessing dependable cryopreservation technology that extends the life of precious biological materials. Whether you’re preserving cell therapies, gametes, or research samples, our controlled rate freezing systems deliver the accuracy and consistency needed to protect sample viability for long-term storage.
