摘要:
L'invention concerne une cellule de dissolution pour solides qui comprend:
un récipient (1) présentant
· une zone conique (6) portant des moyens d'entrée de liquide (9) et contenant un garnissage (10) pour repartir le liquide, · une première (7) et une deuxième (8) zones cylindriques, la première zone (7) étant d'une section inférieure à celle de la deuxième zone (8), les zones étant réunies par un épaulement (11), · la zone conique (6) et la première zone cylindrique (7) formant la chambre de dissolution (24),
un bouchon (2) comportant des moyens de sortie (15) du soluté, des moyens de filtration (3) maintenus entre le bouchon (2) et l'épaulement (11) et placés sur le trajet du soluté entre la chambre de dissolution (24) et les moyens de sortie (15) du soluté.
La cellule et l'appareil la comportant sont utilisés pour l'étude des cinétiques de dissolution des produits pharmaceutiques.
摘要:
A device (1) for preparing an aqueous solution of calcium chloride, particularly for use as a surface deicer, comprising a containment tank (2) which defines a body (3) for containing the water in which the calcium chloride in solid form is to be dissolved and at least one fill opening (4) for the calcium chloride in solid form, the device comprising means for mixing the water with the calcium chloride in solid form in order to obtain a solution of water and calcium chloride, characterized in that the mixing means comprise means (5) for the forced circulation of the fluid contained in the containment body (3) within the containment tank (2). It is also disclosed a device for distributing an aqueous solution for use as a surface deicer comprising a plurality of straight-jet nozzles (52) designed to direct, toward the surface onto which said aqueous solution is to be spread, a respective jet designed to strike a substantially point -like region of the ground.
摘要:
The proposed device for dissolving water-soluble polymer powders comprises a tube with an inlet end through which a polymer solution containing gel components is introduced, and an outlet end through which the polymer solution is removed. In the device, the gel content of the polymer solution is reduced without any reduction in the viscosity of the solution as the tube consists of a plurality of tube sections which can connect to each other and have filters.
摘要:
The present invention relates to a device for use in a cartridge (9), a cartridge, a use of a device in a cartridge and a system for preparing a liquid solution for a medical procedure. The device comprises a hollow body (24) defined by a wall (50) enclosing a cavity space of the body. The body (24) has a first end (52) and a second end (53), and is provided with a least one slit-shaped opening (55) extending through the wall. The first end is open and adapted for receiving liquid to be introduced into the cartridge. The liquid leaves the device through the slit-shaped opening in a flow direction. The slit-shaped opening has a first extension and a second extension substantially perpendicular to the flow direction and to the first extension. The second extension is significantly shorter than the first extension.
