BioGnost’s CryoFix is an appropriate viscosity medium for embedding frozen samples during the process of sectioning in a cryostat. It contains a mixture of resins and glycols soluble in water. Freezing temperature of the mixture is optimal for sectioning in a cryostat and it fits the freezing point of water (0°C). It is used for permeating tissues and forming blocks. That enables sections that can be stained using standard histological techniques. It is conveniently packed for easier handling. It is available in various colors.
