Proven outcomes with controlled-rate freezing. Peer-reviewed workflows using a Grant controlled-rate freezer reported ~94% viable hiPSC-derived cardiomyocytes after cryo-recovery, versus ~60% with older approaches; CRFT brings this level of control to bench-scale iPSC and organoid banking.

Reproducible protocols, not folklore. Define cooling, seeding and thaw ramps (including three-zone “fast–slow–fast” freezing profiles) and lock them. Fewer restarts; less user to user variability, optimal cryo recovered patient derived cellular models. (https://pmc.ncbi.nlm.nih.gov/articles/PMC8909336/Ref)
Right tool for 3D biology. Organoid preservation is size and type dependent. Delicate stem cell and organoid structures need gradual, consistent temperature control during cryopreservation. CRFT offers programmable freeze/thaw profiles that safeguard structural and functional integrity minimising ice damage and maximizing recovery. CRFT standardises slow-freeze workflows (CPA equilibration holds; seed at −8 to −12 °C with Cryopen) where slow freezing is preferred/required for some organoids.

Water-bath-free thaw. Program warm-up to standardise recovery and support cleanroom practice; pair with validated dilution steps(e.g., ROCK inhibitor use for iPSCs as required). (https://pmc.ncbi.nlm.nih.gov/articles/PMC8909336/Ref)
Freeze/thaw without LN₂; store as you prefer. CRFT replaces -80Cfreezer or LN₂ in the process steps; long-term storage is typically in LN₂/vapour or ≤−150 °C per best practice. (https://pmc.ncbi.nlm.nih.gov/articles/PMC8909336/Ref)
