  • Publication number: 20220268658
    Abstract: Disclosed is a method of integrity testing of a single-use system for processing a fluidic material. In the inventive method, a single-use system for processing at least one fluidic material is provided. The single-use system has at least one plastic component. A test gas is applied to a lumen of the single-use system. The test gas has one or more of spectral absorption or spectral emission properties in the infrared spectral range distinguishable from ambient air. At least a part of the single-use system is monitored using an infrared camera. A method of processing a fluidic material by using a single-use system and a test system for integrity testing of a single-use system are also disclosed.

  • Publication number: 20210147100
    Abstract: An inventive drug product filling device for filling a liquid drug product into containers is disclosed. The drug filling device includes a drug product preparer configured for preparing the liquid drug product and a filling station configured for filling the liquid drug product into the containers. The filling station is fluidly coupled to the drug product preparer. A degasser is fluidly interposed between the drug product preparer and the filling station. The degasser has a membrane configured for at least partially separating off gas from the liquid drug product. Methods of (i) filling a liquid drug product into containers, (ii) increasing the accuracy of the filling weight of a liquid drug product in a container, (iii) increasing the stability oxygen-sensitive active pharmaceutical ingredient in a liquid drug product, and (iv) reducing polysorbate aggregate formation in a liquid drug product are also disclosed.

  • Patent number: 7563412
    Abstract: A Reactor (1) for solid phase synthesis comprises a vessel (2), a plurality of filters (3) arranged in the vessel (2) and a plurality of filtrate outlets (4) for evacuating the filtrate out of the filters (3). Each filter (3) is connected to one filtrate outlet (4). The reactor (1) comprises means (3, 4) for delivering a gas into the vessel (2) in a region of the vessel (2) near to the bottom (24) of the vessel (2) and beside the filters (3).
