        MediPrep 820

        The MediPrep 820 series offers quick and easy preparation of up to 8 liters dissolution media in less than 15 minutes. In a single pass, the media for dissolution tests can be precisely mixed, heated, degassed and gravimetrically filled into vessels. Foaming media like SDS (Sodium Dodecyl Sulfate) can also be used.

        Filling can be done at the integrated dosing port or with the optional remote filling hand directly into the vessels.

        The MediPrep 820 provides one inlet for premixed media and one outlet for wastewater. In comparison, MediPrep 821 and 822 offer additional inlets for media concentrates or premixed media. To prevent cross contamination, an automated cleaning procedure is integrated.


        Flexible device for different use cases.
