FIELD: medicine.
SUBSTANCE: method for preparing a frozen-dried material involves the use of a container enclosed by a capsule, has a permeable area, and contains a dispersed material in a carrier fluid, and said capsule having the permeable area is permeated with a penetrator to form a channel through the capsule to connect an internal part and an external part of the container when the penetrator has passed through the permeable area, evaporation of the carrier fluid from the container through said channel and removal of the penetrator from the permeable area. The penetrator contains an integrally tapered element with a hole adjacent to its top, an open base or a hole adjacent to its base, and with a channel passing through the penetrator, connecting these two holes so that the top of the penetrator can pass through the permeable area, and the carrier fluid vapour can be supplied into the top, pass through the hollow internal part of the taper and escape. Said method is implemented inside a sterile cover which temperature can be changed between ambient temperature and temperature whereat the carrier fluid freezes, and which atmospheric pressure can be changed between environment pressure and lowered atmospheric pressure.
EFFECT: simplification of the method.
