A Controlled Rate Freezer (CRF) is a specialised piece of laboratory equipment designed to precisely manage the cooling and freezing of biological samples, cells, tissues, and other sensitive materials. It ensures a gradual and uniform reduction in temperature, preventing the formation of ice crystals that could damage delicate samples. Widely used in cryopreservation, CRFs are essential in medical research, IVF, stem cell storage, and biobanking. With programmable freezing profiles and accurate temperature control, they safeguard sample integrity and improve long-term storage outcomes. The automation of freezing protocols allows for reproducible, reliable results, ensuring consistency in sample preservation.
