Grant Instruments Controlled Rate Freeze Thaw (CRFT)

Controlled rate freezer and thawer that maximizes cell survival without using liquid nitrogen.

Applications

• Transgenic embryology research
• Stem cell research
• Clinical and research samples, e.g. lymphocytes and tissue cell lines in conventional cryovials
• Various mammalian cells including cardiomyocytes, adipose, liver and muscle
• Cord blood derived stem cells
• Adherent cells and stem cells in microplates
• Cell suspensions in numbered/barcoded arrays
• System integrations
• Suitable for applications in veterinarian IVF

Key features and benefits
