An apparatus for dehydrating a liquid sample of biological material has a microwave waveguide that is open to the atmosphere. It has a microwave generator, means for introducing a container of the material into the waveguide, means for evacuating the container, means for rotating the container and means for removing the container from the waveguide. It can include means for moving the container through the waveguide and for sealing it. In a dehydration method, a container of the liquid sample is put into the open waveguide, evacuated, rotated at high speed and microwaved. The container of dehydrated material is then removed from the waveguide. The apparatus and method are particularly suitable for dehydrating vaccines.

La présente invention concerne un appareil permettant de déshydrater un échantillon liquide de matière biologique, ledit appareil ayant un guide d'ondes à micro-ondes qui est ouvert à l'air libre. Cet appareil comprend un générateur de micro-ondes, des moyens pour introduire un contenant de matière dans le guide d'ondes, des moyens pour faire le vide dans le contenant, des moyens pour mettre le contenant en rotation et des moyens pour sortir le contenant du guide d'ondes. L'appareil peut également comprendre des moyens pour déplacer le contenant à travers le guide d'ondes et pour le sceller. Selon un procédé de déshydratation, un contenant de l'échantillon liquide est placé à l'intérieur du guide d'ondes ouvert, mis sous vide, mis en rotation à grande vitesse et exposé aux micro-ondes. Le contenant de matière déshydratée est ensuite sorti du guide d'ondes. L'appareil et le procédé conviennent particulièrement bien à la déshydratation des vaccins.
