  • Publication number: 20240000663
    Abstract: A compact containment system comprises a mixing apparatus, a drying apparatus and a discharge apparatus. The mixing apparatus, which may be used to produce a slurry or solution mixture of solvent and dry powder during drug processing, comprises a dual compartment isolator for safely removing the dry powder from a dry powder container, a mixing vessel, and a negative cascading pressure controller. The drying apparatus comprises a drying unit, such as a thin film evaporator.

  • Publication number: 20220250013
    Abstract: A solids charging containment apparatus and method for mixing a solvent with a dry powder, comprising a dual compartment isolator for safely removing the dry powder from a dry powder container, a mixing vessel, and a negative cascading pressure controller. The dual compartment isolator comprises a staging compartment, a charging compartment and a raw material entry port, which is connected to the staging compartment and configured to isolate the dry powder container from the surrounding atmosphere. The mixing vessel includes a mixing chamber and a solids charging port fluidly connecting the mixing chamber to a containment valve in the charging compartment of the dual compartment isolator. The negative cascading pressure controller generates negative pressure in both the staging compartment and the charging compartment. The containment apparatus and method may be used to produce a slurry or solution mixture of solvent and dry powder during drug processing.

  • Publication number: 20220095610
    Abstract: Container system and method for freezing (and subsequently thawing) a liquid such as a drug substance, such that all containers in a set have a uniform width, hence uniform freeze-path length, in the widthwise direction and perpendicular to major walls of the containers, irrespective of the particular length, height, and volumetric capacity of the various containers in the set. This leads to uniform freezing performance and thereby reduces cryoconcentration. The system also eliminates or reduces ice-bridging, and the potential for containers rupturing during freezing and thawing operations.
