description	Device for metering powder, in particular in clean-rooms, which includes a vessel containing powder and a sealing head with a septum for the vessel, wherein the sealing head is connectable powder-tight with the vessel and the septum powder-tight with the sealing head and the device further includes a vessel holder, which serves to hold the sealing head of the vessel, and the vessel with its opening points downwards, so that the powder can flow out of the vessel, wherein a gap is provided between the sealing head and a holding bowl of the vessel holder, in which a gas flow between the holding bowl and the sealing head can be created. The invention also relates to a use of the device and a metered addition method.
