Abstract

An apparatus for drying microtitration filter tray cavities and filters configured therein using a flow of gas, the cavities each comprising an upper and a lower aperture and the microtitration filter tray being mounted on a chamber designed for the vacuum filtration of microtitration filter trays in a manner that a vacuum can be applied to the lower apertures of the cavities receiving the filters, and includes a heat exchanger which can be mounted on and later removed from the microtitration filter tray and can be heated and comprises at least one inlet aperture and at least one outlet aperture between which a flow of gas may move through the heat exchanger, the heat exchanger being designed to heat the gas flow and to guide it onto the upper cavity apertures, the gas flow being generated by a vacuum pump communicating with the vacuum chamber.
