    Leica EM AFS2 and FSP Freeze substitution system

    Leica AFS 2

    Leica EM AFS 2 is an automatic freeze substitution system for embedding of samples following high pressure freezing and other cryo fixation methods, or progressive lowering of temperature (PLT) to substitute and resin infiltrate chemically fixed specimens.

    The sample is polymerized under UV light and can be cut and immunolabeled for transmission electron microscopy. It is equipped with the Leica EM FSP automatic reagent handling system.

    The Freeze substitution unit has an automatic reagent handling system, giving a one step preparation, reduced workload, and increased reproducibility.

    It minimizes operators contact with toxic media and reduces the risk of losing specimens.
