Grant Controlled Rate Freeze Thaw (CRFT) is a liquid‑nitrogen‑free, controlled rate freezing and thawing system designed to maximise cell survival in cryopreservation workflows. Offering accurate, repeatable control of freezing and thawing rates, CRFT allows users to program, monitor, and export temperature profiles using free software, with interchangeable heads to support cryovials, straws, microplates, and flat plates. Ideal for gamete cryopreservation, embryology, and automated cryopreservation systems, CRFT delivers a safer, low‑running‑cost alternative to traditional liquid nitrogen‑based methods
