Abstract: Double chamber container for holding and combining, e.g., a lyophilizate and a liquid reconstitution medium, comprising an integral cylindrical body (15) with a closure (20, 60) at each of the two ends (5, 70), an upper movable closure (60) to the side of the reconstitution medium and a lower closure (20) to the side of the lyophilizate, a separating stopper (40) that can be moved in the cylindrical body (15) as a seal between the upper chamber (50) and the lower chamber (30), a bypass (35), arranged below the separating stopper (40), having a length L greater than the height H of the separating stopper (40), wherein at the lower end (5) in the wall of the cylindrical body (15) or in the lower stopper (20) there are provided means (21, 25, 28) that allow connection of the interior of the cylindrical body (15) to the environment during the lyophilization.

Abstract: The present invention relates to an apparatus for determining the shear sensitivity of particles in solutions and methods of determining the respective shear velocities or the respective shear stress.

Abstract: The invention relates to a method for preparing powder mixtures, one component consisting of spray-dried powder. The invention also relates to a method for coating spray-dried particles with nanoscale particles, a method for mixing spray-dried powder with microscale particles and a method for covering carrier substances with spray-dried particles.

Abstract: The invention relates to a double chamber container for holding and combining two separate components, at least one of which is liquid, comprising a cylindrical body (15) with a closure (20, 60) at each of the two ends (5, 70) of the body (15), an upper closure (60) at the liquid component end and a lower closure (20) at the solid component end, and a separating stopper (40) in the cylindrical body (15) as a seal between the two chambers (30, 50), the separating stopper (40) having a height H and the upper closure (60) at the liquid component end being movable by the application of pressure, and comprising on its underside a hollow needle (45) with a length L having at least one opening (42) which is provided at the end opposite the tip, where H <L.
